There are various types and models of ICP-MS spectrometers and many reasons for their failure and inaccurate operation. The basic thing when dealing with such situations is knowing the company's instructions for the use of a given spectrometer model. If this is not enough to find and remove the cause of a given malfunction, it is best to use the help of a person who is familiar with this measurement technique and uses the same or a similar spectrometer model, first remotely (using e.g. TeamViewer or similar software). As a last, if this does not help, you should seek help from the spectrometer manufacturer's service centre. You also need to be sure that the solutions used to regulate the spectrometer are prepared correctly, which is where you should start.
