ICP-MS is a multi-element technique by which the concentrations of elements and isotopes at sub-ppb level can be determined. The paper begins with a description of the operating principles and continues with a presentation of the basic parameters for correct operation of the instrument. These include: (i) instrument base; (ii) sensitivity (intensity of the signal); (iii) vacuum values; (iv) stability of the intensity of the signal in time; (v) calibration of the mass number; (vi) resolution; (vii) limit of detection. The paper concludes with a discussion of data acquisition and also semi-quantitative and quantitative analysis.
