Atomic absorption spectrometer with flame atomization Kvant-2AT

The spectrometer is designed for quantitative determination of metal impurities in liquid samples of various origin and composition by atomic absorption and emission spectra. With automatically adjusted six-lamp turret and automatic monochromator. Determines up to 70 chemical elements. Limits of detection from 0.05 µg/l.

Areas of use

Monitoring of environmental objects (water, air, soil)

Analysis of food products and raw materials for their production

  • Agrochemistry
  • Medicine and pharmacology
  • Geology and geochemistry

Chemical, petrochemical, metallurgical and other industries

  • Scientific research

Optical system

Monochromator with holographic diffraction grating and automatic wavelength setting

  • A photodetector based on a silicon photodiode with an original signal amplification circuit that provides a high signal-to-noise ratio, high sensitivity in a wide range of the spectrum, and linearity of the photometric characteristic.

Basic Analysis Modes

direct absorption with flame atomization

atomization in a quartz cell (methods of cold vapor and volatile hydrides)

atomic absorption with flow-injection concentration

atomic emission

The delivery set of an atomic absorption spectrometer must include:

1) computer and software for instrument control and processing of measurement results;

2) the compressor is oil-free.
