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.

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.

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⁻).

By using the WatchGas rechargeable motor-driven ATEX pump, a diffusion-type gas detector can easily be converted into a sampling-type gas detector, allowing for gas detection even in areas inaccessible to users. Furthermore, by connecting additional probes, accidents can be prevented before entering confined spaces. It is extremely user-friendly, as it can be operated with the push of a button. The LED indicator allows for easy monitoring of operational status, enabling real-time responses to pump issues. Additionally, it can be charged via USB Type-C, requiring up to 7.5 hours for a full charge, and can operate for over 20 hours after being fully charged. With an explosion-proof design, it has obtained KCs, IECEx, and ATEX certifications, making it safe to use in environments where flammable gases are present.
