Atomic absorption spectrometer with electrothermal atomization MGA-1000

The third generation of spectrometers of the MGA series. Intelligent diagnostic system. Silent atomization.

Electrothermal atomization of a sample in a heated graphite tubular cell with a Lvov platform , with correction of non-selective spectral noise based on the use of the Zeeman effect for objects with pronounced non-selective absorption.

Designed to measure the content of elements in a wide range of objects. This device has the highest efficiency in the analysis of samples with a complex matrix composition: sea water, blood, urine. It is possible to directly analyze samples without preliminary preparation and determine selenium (Se) and arsenic (As) at the level of tenths of MPC without using a mercury-hydride attachment.

The atomizer and cuvette are protected from overheating.

Main applications:

  • environmental control: measurement of the content of elements in water, soil, bottom sediments, atmospheric air, as well as tissues of plant and animal origin;
  • medicine and veterinary laboratories : analysis of tissues and fluids of biological origin (blood, urine, hair, animal products, etc.)
  • controlling and certifying laboratories : analysis of food and feed, analysis of waste, natural, drinking water and air;
  • quality control of alcoholic products : the content of a wide range of elements in alcoholic beverages and the determination of authenticity;
  • forensics : identification of impurities and trace elements.

It is also used in geological exploration, metallurgical industry, scientific research.

The basic equipment of the MGA-1000 includes:

  • automatic monochromator;
  • automatically adjusted six-lamp turret;
  • autosampler;
  • local cooling system.

The spectrometers can be equipped with a RGP-915 mercury-hydride attachment for the analysis of mercury and hydride-forming elements.

Hollow cathode lamps and high-intensity electrodeless discharge lamps are used as light sources. Hollow cathode lamps and electrodeless lamps can be installed in the turret at the same time.

Spectral interference correction

High selectivity is associated with the use of Zeeman modulation polarization spectrometry. This correction of non-selective absorption (background signal attenuation) is recognized throughout the world as a “reference method” for the determination of small contents of elements in samples of complex composition.
