Atomic Absorption Spectrometer MGA-1000
MGA-1000 is a graphite furnace atomic absorption spectrometer based on the patented Zeeman High Frequency Polarization Modulation (ZHFPM) technique.
MGA-1000 is intended for determination of a wide range of elements in various types of samples (water, soil, foodstuffs, fodders, pharmaceuticals, etc.).
The instrument performs high selectivity and sensitivity of analysis.
MGA-1000 is intended for determination of a wide range of elements in various types of samples (water, soil, foodstuffs, fodders, pharmaceuticals, etc.).
The instrument performs high selectivity and sensitivity of analysis.
Graphite Furnace Atomic Absorption Spectrometry (GFAAS) provides optimal combination of high selectivity and sensitivity with low running cost. The unique ZHFPM background correction technique ensures effective compensation of intense and rapidly changing spectral interferences and brings routine analysis of complex samples to new heights.
ZHFPM background correction is effective in all spectral range
MGA-1000 optical scheme
- Simultaneous measurement of total and background absorptions
- Simple direct analysis of samples with high salinity and organic content: blood, body fluids, sea water, brines, food and soil digests, etc.
- Smart 47-position autosampler supports standard centrifuge-type tubes
- Effective cooling system included
- Stabilized temperature platform furnace (STPF) concept implemented
- No flammable gases nor air compressor needed, argon only is used for operation
- Standard graphite tubes (28 mm) of both Massman and L’vov types are available, tube lifetime is prolonged
- Quasi-double beam optics eliminate drifts and enable direct work with no warm-up needed
- Low detection limits and direct determination of As, Se, and other elements at levels from 1 ppb without hydride generation technique or preconcentration
- Analysis of Na, K, Mg, and Ca from sub-ppb to hundreds of ppm levels
- 6-lamps turret supports both hollow cathode lamps and electrodeless discharge lamps (EDL)
- Compact size of instrument and noiseless operation: fits in regular lab, no requirements for separate room
- Cold Vapor/Hydride Generation accessory for Hg analysis
