Atomic Absorption Spectrometer MGA-1000
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.
Key technologies
- Simultaneous measurement of total and background absorptions with Zeeman High Frequency Polarization Modulation (ZHFPM) background correction
- Electrodeless Discharge Lamps (EDL) provide low detection limits and direct As and Se determination at sub-ppb levels without hydride generation technique
- Stabilized temperature platform furnace (STPF) concept is implemented
- Quasi-double beam optics eliminate drifts and enable direct work with no warm-up needed
- Gas-phase dynamic dilution system expands the list of applications – analysis of trace elements as well as major components is possible
- Compact and effective cooling system in the starter-pack
- Cold Vapor/Hydride Generation apparatus is available
INDUSTRIES
MGA-1000 spectrometer is an excellent solution for reliable and accurate trace elements analysis and major cations determination in various fields:
- Environmental monitoring

Graphite Furnace Atomic Absorption Spectrometry (GFAAS) provides optimal combination of high selectivity and sensitivity with low running cost.
High analytical performance
- Simple direct analysis of samples with high salt and organic content: blood, body fluids, sea water, brines, food and soil digests, etc.
- With EDLs, determination of Sb, As, Bi, Cd, Se, and other elements doesn’t require pre-concentration and hydride generation technique
- Gas-phase dynamic dilution system and know-hows of Lumex Instruments enable analysis of Na, K, Mg, and Ca from sub-ppb to hundreds of ppm levels
