CETAC M-7600 Mercury Analyzer Operator's Manual

1 Introduction
Overview
The CETAC QuickTrace M-7600 mercury analyzer measures trace levels of
mercury in aqueous solution by Cold Vapor Atomic Absorption Spectrometry
(CVAAS). CVAAS does not require heating the sample with a flame, plasma, or
furnace. The mercury analyzer’s modular design permits remarkably easy
maintenance access and a reduced countertop footprint. Sturdy construction,
drift-stabilized double beam optics, thermal and electro-optical lamp
stabilization, and an unusually stable “non-foaming” Gas-Liquid Separator (U.S.
Patent #5,792,663) collectively afford exceptional structural integrity and
signal stability. The QuickTrace M-7600 exhibits a high signal-to-noise ratio
and ultra-trace detection limits for an absorbance system that is fully
compliant with EPA CVAA methods such as 245.7, 245.1, 245.5, SW846 7470
and 7471.
