Instran Online Nitrate Concentration Meter

Instran Online Nitrate Concentration Meter

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⁻).

Instran Online Nitrite Concentration Meter

Instran Online Nitrite Concentration Meter

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.

Instran Online Copper Ion Concentration Meter

Instran Online Copper Ion Concentration Meter

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.

Instran Online Low Concentration Iron Ion Concentration Meter

Instran Online Low Concentration Iron Ion Concentration Meter

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.

Instran Online Sodium (Na) Concentration Meter

Instran Online Sodium (Na) Concentration Meter

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

Application Example: Greenhouse Gas Concentration Measurement - Ultrasonic Gas Concentration Meter

An ultrasonic gas concentration meter that is actively used in a wide range of fields, including healthcare, electronics, and industry. We have compiled a collection of case studies highlighting selected examples of its adoption.

As greenhouse gases, carbon dioxide, methane, and sulfur hexafluoride (SF6) are mentioned, among which sulfur hexafluoride is widely used in power-related processes and as an insulating gas in semiconductors. In terms of global warming potential, if carbon dioxide is set at 1, sulfur hexafluoride is 22,800. In recent years, efforts have been made by various companies to prevent the release of sulfur hexafluoride into the atmosphere by installing recovery devices and other measures. Our ultrasonic gas concentration meter is incorporated into such recovery devices and is also used for portable measurement of SF6 concentration. Additionally, in Japan, our ultrasonic gas concentration meter is used for measuring the concentration of alternative refrigerants, which are required to be recovered after use under the Freon Recovery and Destruction Law, as it can measure concentrations that other methods cannot.

Case Study: Marine (Tanker) Zirconia Oxygen Analyzer

Active in a wide range of fields including electronics, industry, and healthcare. We have picked up selected cases and compiled them into a case study collection.

When transporting heavy oil with a tanker, friction between the heavy oil and air inside the tank can cause an explosion due to turbulence during operation. To prevent this, tankers mix nitrogen or inert gases with the air to avoid explosions. Nitrogen is generated using a nitrogen generation unit, and inert gases are reused from boiler exhaust. This is called the Inert Gas System (I.G.S). Our oxygen meters are incorporated into the I.G.S, measuring the O2 concentration in the exhaust gas, and are actively used worldwide to prevent explosions during operation, as well as during loading and unloading. Achievements: Over 1,000 vessels. Target models: TB-2F series *There are many other industries where our products are actively used. Please download our case study collection and consult with us.
