Complex of equipment «Clean workplace» for sample preparation during trace elements analysis: a new development of the «ANALIT «company

Abstract

Most of the errors in determining the trace contents of the elements are attributed to contamination at the stages of sample preparation and preparation of calibration solutions. One of the main sources of contamination is the laboratory air containing detectable impurities in the form of dust and aerosols. Reagents, dishes, dispensers and chemist himself may also act as sources of pollution. Background contents of the elements in a laboratory can be rather significant and lead to serious accidental and systematic errors, especially for wide-spread elements: Al, Si, Ca, Mg, Na, Fe, Zn, Cu, P, etc. A new development of the ANALIT company «Clean workplace» intended for sample preparation for trace spectral analysis is designed to solve the aforementioned problems.
