ELIS-121 (NO3) Electrode

Add to comparison


Laboratory solid-contact nitrate-selective electrode. Suitable for operation with various modern laboratory ion-meters. An ion-selective electrode is coupled with a reference electrode.

Nitrates measurement is quite widely used in analytics. Note that each research subject requires a separate analytical method which implies preliminary sample preparation. In calculating the final contents of nitrates, these methods use special coefficients which take account of the sample mass, volume of the extractive solution, dilution, extraction rate, etc.

Choosing an ion-selective electrode, first of all make sure the measurement technique is applicable to the specific conditions. In case of any problems, contact the experts or developers of the measurement methodology. Remember that most ion-selective electrodes do not offer high selectivity and demonstrate a fairly narrow measurement range which makes up 4 to 6 orders of concentrations. While making decision to purchase a specific electrode, it is important to thoroughly estimate its specifications, recommendations for use and impeding ions.
