M-7600 – CVAA

The QuickTrace® M-7600 Cold Vapor Atomic Absorption (CVAA) Kwik Analyzer easily achieves an ultra-low detection limit of <0.5 ng/L, which is needed for those laboratories using various European standards, such as Din ISO 16772, EN-13806, EN-1483, and ISO 12846. The QuickTrace® M-7600 is ideal for measuring samples in a very wide range from ultra-low to sub-mg/L mercury concentrations. The M-7600 is suitable for various types of laboratories such as environmental labs, industry, and universities.

Description

The QuickTrace^® M-7600 Cold Vapor Atomic Absorption (CVAA) mercury analyzer combines the proven technologies of its predecessors together with modern techniques for ultra-fast data collection. The M-7600 is used to measure samples with various matrices after digestion, such as: water and wastewater, soil and sediment, biological tissue and fluids.

The QuickTrace^® M-7600 mercury analyzer is also versatile enough to measure samples with high concentrations (>500 μg/L) without dilution. The M-7600 is capable of switching between low mg/L and ng/L analysis without having to change hardware or pump hoses. Using the proven and reliable CVAAS technique and combined with the multi-tasking Windows-based software, the QuickTrace^® M-7600 is the most stable and sensitive atomic absorption analyzer on the market. For ultra-trace analysis, we recommend our sample changer housing (ENC-560) to protect the samples from contamination from the laboratory environment. The ENC-560 (with extraction) also protects your investment against the aggressive acidic vapors that are normally present in and around acid-digested samples.

Performance

You can expect excellent short and long term stability from the QuickTrace® M-7600 CVAAS analyzer. Instrument detection limits of less than 0.3 ng / l are typical for this analyzer, with less than 4 minutes sample time and less than 25 ml sample required.

Ultra-trace detection limit (< 0.5 ng/L IDL)
Linearity better than 4 orders
Dynamic range < 0.5 ng/L (ppt) to > 500 μg/L (ppb)
The automatic flush technology is activated after detection of concentrations > 1 mg/L
Short-term precision (%RSD @ 95% Reliability) < 1.2% @ 20 ng/L, n=5
Short-term precision (%RSD @ 95% Reliability) < 6.0% @ 5 ng/L, n=5
