Inductively coupled plasma mass spectrometer
Icp-ms, or inductively coupled plasma mass spectrometer, is an analytical instrument that combines ICP technology with mass spectrometry. ICP using places strong power on the inductance coil of high frequency radio frequency signal of high temperature plasma is formed within the coil, and through the gas drive, ensure the balance of plasma and ionization, in icp-ms, ICP have the effect of ion source, high temperature plasma makes most of the elements in the sample knock off an electron to form a plus. Mass spectrometry is a mass screening and analyzer, which can detect the strength of a certain ion by selecting ions with different mass/nucleus ratio (m/z), and then analyze and calculate the strength of a certain element, which can measure the content of trace elements in the solution below PPB.
Low detection limit, high precision, high sensitivity, fast analysis speed, quantitative analysis, semi-quantitative analysis, qualitative analysis.
