What's the difference between direct reading spectrometer and X ray fluorescence analyzer, and other ones are elemental analysis. What are their differences?
Elemental analysis instrumentation: atomic absorption, ICP (plasma emission spectrometer (ICP-MS), plasma mass spectrometry (GD), glow discharge spectrometer) and GD-MS (glow discharge mass spectrometer), DC arc spectrometer. All of the above elements analysis component main users in the sample, of course these are just the spectral series, series of chromatographic analysis the instrument can also be part of the element contentIn addition to the above instruments, there are some main elements such as CHNSO metal analyzer, detection of five elements in total organic carbon analyzer, detection TOC analyzer, detection of food and environmental samples of mercury in mercury analyzer and so onAll of the above mentioned instruments are determined by the total amount of elements, and the elemental valence states can not be analyzed,
Direct reading spectrometer can be divided into three types: vertical, desktop and mobile, and the stability and precision of analysis are descending in turnX ray fluorescence is mainly divided into three types: wavelength, energy and portable. The accuracy of analysis is also descending according to the order in sequence. The function of these elements is followed by the analysis of elements content, semi quantitative qualitative analysis and qualitative analysis
Direct reading spectrometer and X ray fluorescence belong to emission spectrum, not the absorption spectrum that you call. It belongs to portable moving spectrometer by dolly. It is one kind of direct reading spectrometer
