Description
Atomic absorption spectrometer with flame atomization Kvant-2m with built-in hydride system
High Performance Elemental Analysis
The spectrometer is designed for quantitative determination of metal impurities in liquid samples of various origin and composition by atomic absorption and emission spectra.
The spectrometer includes a built-in hydride system for quantitative elemental analysis using atomic absorption spectra of hydride-forming elements, such as, for example, arsenic, antimony, selenium, tellurium, and mercury.
