ICPMS is a technique used to find elements in a sample by ionizing and measuring their mass-to-charge ratios.

• ICPMS stands for Inductively Coupled Plasma Mass Spectrometry.

• It involves ionizing a sample using an inductively coupled plasma source.

• The ions are then separated based on their mass-to-charge ratios using a mass spectrometer.

• The detected ions can be used to identify and quantify the elements present in the sample.

• ICPMS is commonly used in various fields such as enviro...read more
