As part of contracts and orders after prior approval by the Head of Laboratory. Tests are performed only by authorized personnel of the Laboratory.
Ion chromatography coupled with a mass spectrometer is widely used in environmental analysis. It gives great possibilities in the determination of species of selected elements, after the use of appropriate analytical columns, selection of eluents and operating parameters of the analytical equipment.
Depending on the parameter being analyzed and the sample matrix, it is possible to measure concentrations of the order of ng/L. Routinely, the limits of quantification range from tenths of µg/L to several µg/L.
