The mechanism by which sulfurous gas and sulfur dioxide gas (SO2 gas) affect the human body.
Volcanic accidents remind us of the disaster caused by the eruption of Mount Ontake in 2014. However, in terms of the number of volcanic incidents, accidents due to volcanic gas poisoning are overwhelmingly more frequent and are reported every year. Additionally, with the revision of the Active Volcano Law, local governments are obligated to ensure the safety of tourists, increasing the importance of monitoring volcanic gases. This time, I will explain the mechanisms by which volcanic gases (sulfur dioxide and sulfurous gas) affect the human body. <Sulfurous Gas and Sulfur Dioxide (SO2)> Harmful gases such as sulfurous gas and sulfur dioxide (SO2) damage the epithelial lining of the airways. This damage leads to the accumulation of inflammatory cells in the airways, causing inflammation. Due to this inflammation, the airways become sensitive, leading to airway constriction and triggering asthma attacks. The type of inflammation varies among individuals, resulting in allergic asthma or COPD. It is believed that various factors, including genetic and environmental influences, contribute to these types. Therefore, individuals have different tolerances to the gas, and there have been reports of asthma patients experiencing attacks even at low concentrations of around 0.2 ppm. Additionally, it is said that there are many undiagnosed asthma patients who are unaware of their condition.
The mechanism of the impact of volcanic gases (SO2) on the human body and the importance of early detection.
In the field of disaster prevention and crisis management, responses to unexpected natural disasters are required. In particular, accidents caused by volcanic gases not only evoke memories of the Ontake Mountain eruption disaster but are also reported every year, making their risks significant. With the revision of the active volcano law, local governments are mandated to ensure the safety of tourists, increasing the importance of monitoring volcanic gases. Our product helps understand the mechanisms by which volcanic gases (sulfur dioxide and sulfurous gas) affect the human body and supports rapid responses. Sulfur dioxide and sulfurous gas can damage airway epithelium and trigger inflammation, potentially leading to asthma attacks. Since individual tolerance to gases varies and effects can occur even at low concentrations, early detection and information sharing are essential. 【Usage Scenarios】 - Monitoring areas around volcanoes - Understanding gas concentrations during evacuation guidance - Safety management for tourists 【Benefits of Implementation】 - Early detection of rising gas concentrations, contributing to swift evacuation guidance - Supporting accurate situational judgment through gas information sharing among stakeholders - Reducing the risk of volcanic gas poisoning accidents

Fluorine concentration can be measured with a wide range and high precision from a minimum of 0 to 0.5 ppm to a maximum of 0 to 100 ppm!
We adopt the SKA method to calculate concentration based on the difference in concentration between a standard solution of known concentration and the sample. By comparing the potential differences, we can minimize the impact of the measurement environment on the results. During measurement, reagents are used to adjust the pH. This removes interference from ions other than fluoride, enabling high-precision measurement of fluoride concentration.

Continuous measurement of total chlorine concentration in water using an ion-selective electrode method!
Advantages This method is a very simple chlorine measurement technique. It consumes a small amount of reagents, and chromate ions, which interfere in amperometric methods, do not cause interference here. Conductivity and calcium, which are significant interferences in the DPD method, do not interfere either. Measurement Principle – ISE Electrode Analysis is performed using the Standard Known Addition (SKA) method. Two measurements are taken, and the concentration is calculated from the difference between the two and the slope during the calibration curve creation. The reference for calculating the results is not an absolute value but the relative difference in mV, so any changes that may occur in the matrix sample are corrected by both of these lectures. This allows for the avoidance of external interference. Measurement Method It is based on the measurement of iodide. Through the reaction of chlorine, buffer solution, and potassium iodide reagent, chlorine reacts with potassium, releasing iodide. Chlorine displaces iodide. Subsequently, the ISE electrode measures the iodide, and the amount of iodide measured corresponds to the chlorine in the sample.
It is a colorimetric online chlorine measuring device. It allows for regular sampling and analysis of total chlorine concentration.
Measurement Principle Potassium iodide reacts with chlorine in acidic media, producing a yellow color. When a sufficient amount of titrant is added, it becomes colorless again, allowing the concentration of chlorine to be calculated based on the amount of titrant used. Features Potassium iodide reacts with chlorine in acidic media, producing a yellow color. When a sufficient amount of titrant is added, it becomes colorless again, allowing the concentration of chlorine to be calculated based on the amount of titrant used.
Continuous measurement of water hardness is possible!
Method – Colorimetric Analysis After adding the reagent and setting appropriate conditions for the sample, the titrant is filled. Thanks to the minimum addition amount of the module syringe driver being controlled in 0.015 mL increments, very high precision is achieved. Furthermore, the software has been improved to speed up the initial dosing, and as it approaches the inflection point, the titrant is added slowly, enhancing accuracy.
Continuous measurement of nitrate concentration in water is possible!
Method - Ion Selective Electrode Reagent 1 is added before analysis to activate the electrode. After that, the first measurement is taken. Next, a small amount of a high-concentration nitrate solution is added, and a second mV measurement is performed to calculate the results. If an extraction solution is used, cleaning with an ammonia-based cleaning solution is necessary after analysis to prevent cross-contamination. Many probes are affected by interference from nitrite and chloride, but in this method, using the extraction solution at the beginning of the analysis completely removes the influence of these two ions. Therefore, the only ion affecting the measurement is the nitrate ion (NO₃⁻).
High-precision measurements are possible while eliminating the influence of magnesium!
After adding the reagents to prepare the sample under specified conditions, the injection of the titrant is performed. The minimum injection volume (0.015 ml) achieved by the module's syringe driver ensures very high precision, with a maximum difference of only three drops even in two consecutive measurements using the same standard sample. Additionally, improvements in the software have accelerated the injection of the titrant in the initial stages, while slowing down the injection rate as it approaches the endpoint, ensuring even higher accuracy. This method is a modification of the method developed by Reilly (published in Analytical Chemistry). By adjusting the pH of the solution, magnesium precipitates and is not included in the titration target. It is specialized for calcium even in the presence of large amounts of magnesium. The measurement wavelength is adjusted to the calcium–calcon (Ca–Calcon) complex, while the reference wavelength is set to the EDTA–calcon complex, allowing for accurate and reproducible detection of the endpoint.
Even at a concentration of 100 ppb, which is often considered the legal limit in drinking water, a significantly high absorbance can be obtained.
After adding the sample to the measurement cell, several reagents are added to adjust the solution conditions (such as pH and the atomic valence of elements). Subsequently, a blank measurement is performed to correct for the effects of temperature and turbidity. Then, the final reagent is added, which reacts with the solution to produce color and is measured at the appropriate wavelength. Thanks to the photometer used, results can be obtained with very high accuracy. This method is based on the reaction in which nitrous acid generated from nitrite ions undergoes a diazotization reaction with sulfanilamide, forming a vivid colored diazo dye.
Continuous measurement of copper ion concentration in water is possible!
Method - Colorimetric Analysis After adding the sample to the measurement cell, several reagents are added to adjust the conditions of the solution (such as pH and oxidation state). Subsequently, a blank measurement is performed to correct for the effects of temperature and turbidity. Then, the final reagent is added, which reacts with the solution to produce a color that is measured at the appropriate wavelength. The photometer used allows for highly accurate measurement results. This method is based on the reduction of copper(II) to copper(I) in acidic solutions. The neocuproine reagent specifically reacts with cuprous ions (Cu⁺). If present, iron can also be reduced to iron(II) (Fe²⁺) and may react with neocuproine. This method is specific to copper, and the cuprous-neocuproine complex has a clear and relatively strong absorbance, allowing for the measurement of low concentrations of copper at the ppb level. The influence of iron can be removed with additional reagents.
Continuous measurement of low concentrations of iron ions in water is possible!
Method - Colorimetric Analysis After the sample is introduced into the measurement cell, several reagents are added to adjust the solution conditions (such as pH and the valence of elements). Subsequently, a blank measurement is conducted to correct for the effects of temperature and turbidity. Then, the final reagent is added, which reacts with the solution to produce a color that is measured at the appropriate wavelength. Depending on the photometer used, the results are obtained with very high precision. Trivalent iron (Fe³⁺) is reduced to divalent iron (Fe²⁺) by hydroxylamine hydrochloride. The divalent iron ions react with ferrozine in a buffer solution adjusted to a pH range of 5 to 7, forming a pink complex. This method allows for the measurement of very low concentrations of iron. The reagents used are stable. If it is necessary to measure total iron, the stirring time can be extended to ensure that the iron is completely dissolved in an acidic medium.
Continuous measurement of silica concentration in water is possible!
Method - Colorimetric Analysis After introducing the sample into the measurement cell, several reagents are added to adjust the solution conditions (such as pH and valence elements). A blank measurement is then performed to correct for the effects of temperature and turbidity. Next, the final reagent is added, which reacts with the solution to develop color, and this is measured at the appropriate wavelength. Depending on the photometer used, the results are obtained with very high precision. Silicon (silica) reacts with molybdate reagent in an acidic environment to form a yellow silicomolybdic acid complex. This complex is reduced by ascorbic acid, resulting in a blue color known as "molybdenum blue." The concentration of this blue color is proportional to the silica concentration. The developed blue color is very intense, providing excellent accuracy and reproducibility. This method can also measure very low concentrations of less than 50 ppb. *Interfering Factors Phosphates and tannins: can be removed by oxalic acid Hydrogen sulfide and large amounts of iron: cause interference
Continuous measurement of low concentration silica in water is possible!
Method – Colorimetric Analysis After adding the sample to the measurement cell, multiple reagents are added to adjust the solution to the specified conditions. Next, a blank measurement is performed to correct for the effects of temperature and turbidity. After that, the final reagent is added, which reacts with the solution to produce color, and this is measured at the appropriate wavelength. The photometer used allows for measurements with high precision. This method exclusively forms B-type molybdoceric acid, enabling the highly sensitive measurement of trace silica in high-purity water, as required in power plants and the electronics industry. Furthermore, the new formulation of reagent 1 has reduced the time required for the reaction to complete. Although reagent 1 is relatively expensive, the amount needed for use is very small, making it economical.
Continuous measurement of sodium concentration in water is possible!
Method - Ion Selective Electrode Analysis is performed using the Standard Known Addition method (SKA). This process involves two measurements. The difference between the two and the slope obtained during calibration are used to calculate the concentration. By using both measurement values, changes in the matrix sample are corrected, and the calculation of results is based on the relative mV difference rather than absolute values. This helps to avoid external interference. Measurement Principle The sample is adjusted to pH 8-11 using an Ion Strength Adjuster (ISA). After that, the first measurement is taken. Next, a small amount of high-concentration sodium solution is added. Finally, a second mV reading is taken, and the results are calculated. The advantage of this method is that the rapid response of the electrode allows for quick analysis. The main interfering cations are either absent or present in very small amounts. Furthermore, the ISA solution prevents these interferences. *Interfering factors: Lithium, Potassium, Rubidium, Ammonia, Silver, Thallium
