Atomic Absorption Spectrometer MGA-915MD
The MGA-915MD series is where sensitivity meets economy. Productive and easy-to-handle graphite furnace atomic absorption spectrometer.
Experience simplicity of complex samples analysis with unique High Frequency Zeeman background correction technology.
KEY TECHNOLOGIES
- Zeeman High Frequency Polarization Modulation (ZHFPM) background correction
- Accurate spectral interference correction even for complex sample matrices thanks to simultaneous measurement of total and background absorptions
- Direct As and Se determination at ppb and sub-ppb levels without hydride generation technique is possible due to bright and stable electrodeless discharge lamps (EDL)
- The stabilized temperature platform furnace (STPF) concept realized
- Pseudo-double beam optical system compensates for drifts of various nature e.g. spectral lamps, electronics. No warm-up required
- Cold Vapor / Hydride Generation technique available
INDUSTRIES
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.
HIGH ANALYTICAL PERFORMANCE
- Complex samples with high salt and organic content injected to the furnace without pretreatment. Simple and direct analysis of beverages, biological fluids, sea water and brines possible
- A number of elements for which EDLs are produced e.g. Sb, As, Bi, Cd, Pb, P, Se, Te, Tl, Sn and Zn, can be determined at lowest levels without pre-concentration and hydride generation technique
LOW-COST ANALYSIS
- Standard graphite tubes (28 mm) of both Massman and L’vov type are available
- The autosampler accommodates standard plastic vials and Eppendorf®-type tubes
