- Model MGA-1000 - Atomic Absorption Spectrometer


The MGA-1000 series of graphite furnace atomic absorption spectrometers crystallizes intuitive technology and exceptional handling. The unique High Frequency Zeeman background correction system ensures effective compensation of intense and rapidly changing spectral interferences and brings routine analysis of complex samples to new heights.

  • Zeeman High Frequency Polarization Modulation (ZHFPM) background correction
  • Simultaneous measurement of total and background absorptions provides accurate background correction even for complex sample matrices
  • High intensity electrodeless discharge lamps (EDL) ensure lower detection limits compared to traditional hollow cathode lamps (HCL) and make possible direct As and Se determination at ppb and sub-ppb levels without hydride generation technique
  • The stabilized temperature platform furnace (STPF) concept realized
  • Instrument drifts arising from various sources e.g. spectral lamps, electronics, are effectively compensated by quasi-double beam optical system. No warm-up needed
  • Cold Vapor / Hydride Generation technique available
  • Noiseless operation and small size

Graphite furnace atomic absorption spectroscopy (GFAAS) is an excellent solution for trace element analysis in various fields:

  • Environmental monitoring
  • Water treatment
  • Food and Beverages
  • Agriculture
  • Pharmaceutics and Life science
  • Medicine and Biochemistry
  • Forensics and Clinical research
  • Petrochemistry and Refineries
  • Process control and Material analysis
  • Science and Research

For laboratories with low-moderate sample throughput, GFAAS secures optimal combination of high selectivity, sensitivity and low-cost analysis.

  • Simple and direct analysis of samples with high salt and organic content including blood and biological fluids, sea water and brines, some food and soil digests, etc.
  • Lower detection limits for the elements for which EDLs are available. Thus Sb, As, Bi, Cd, Pb, P, Se, Te, Tl, Sn and Zn can be determined in variety of complex samples without pre-concentration and hydride generation technique

  • Plug & Measure convenience
  • User-friendly software for setting operating conditions, results storage and processing
  • PC controlled 6-lamp turret designed for main types of Hollow Cathode Lamps and Electrodeless Discharge Lamps
  • Smart autosampler with all routine functions
