Scope
This part of ISO 17294 specifies the principles of inductively coupled plasma mass spectrometry (ICPMS) and provides general directions for the use of this technique for determining elements in water. Generally, the measurement is carried out in water, but gases, vapours or fine particulate matter may be introduced too. This International Standard applies to the use of ICP-MS for water analysis. The ultimate determination of the elements is described in a separate International Standard for each series of elements and matrix. The individual parts of this International Standards refer the reader to these guidelines for the basic principles of the method and for configuration of the instrument.
Purpose
In the last 16 years new developments for the metal analyses with inductively coupled plasma mass spectrometry (ICP-MS) took place. The use of the collision cell inductively coupled plasma mass spectrometer (CC-ICP-MS) and triple quad ICP-MS has increased in the laboratories. For this reason the text of ISO 17294-1 need to be adapted. Therefore many criteria in the text shall be modified and updated for use with the new instrumentation available. For the end-user of the ICP-MS, the criteria have to be clear and applicable to be of any value for the user of the ICP MS eg. for accreditation purposes.
