Animal feed analyzer MGA-1000

soilwatersalinity

Overview
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 provides high selectivity and sensitivity of analysis.

Key technologies
Graphite Furnace Atomic Absorption Spectrometry (GFAAS) combined with the ZHFPM background correction technique enables effective compensation of intense and rapidly changing spectral interferences and routine analysis of complex matrices.

Features and advantages

• Simultaneous measurement of total and background absorptions
• Direct analysis of samples with high salinity and organic content: blood, body fluids, sea water, brines, food and soil digests
• 47-position autosampler compatible with centrifuge-type tubes
• Closed-loop water cooling for the atomizer
• Stabilized temperature platform furnace (STPF) implementation
• No flammable gases or air compressor required; high-purity argon only
• Standard 28 mm graphite tubes of Massman and L’vov types available with extended lifetime
• Quasi-double-beam optics reduce drift and allow operation without warm-up
• Low detection limits and direct determination of As, Se and other elements down to ~1 ppb without hydride generation or preconcentration
• Analysis of Na, K, Mg and Ca from sub-ppb to hundreds ppm
• 6-lamp turret supporting hollow cathode lamps and electrodeless discharge lamps (EDL)
• Compact dimensions and quiet operation for placement in standard laboratories
• Optional RGP-915 cold vapor / hydride generator for Hg and hydride analyses
