CETAC QuickTrace M-7600 Mercury Analyzer
Chapter 1: Introduction
System Features
The QuickTrace M-7600 incorporates the following features to form an
automated, integrated mercury analysis system.
‣ Computer-controlled four-channel high-performance peristaltic pump
(12-roller pump head).
‣ Ozone-free Hg Lamp. No lamp ventilation is needed.
‣ Thermally controlled Hg lamp housing (for a stabilized Hg vapor lamp).
‣ Stable high performance Gas-Liquid Separator (GLS). (U.S. Patent
#5,792,663). Non-foaming/non-bubbling “thin liquid film” GLS design,
which allows trouble-free direct analysis of blood, urine, and fish tissue
digests as well as standard water and waste analysis.
‣ Rigid, shock and vibration-isolated optical rail (mounting the Hg lamp,
collimator lens, absorption tubes, camera, CCD detector, and A/D
converter).
‣ Precise, self-aligning optical mounts, no optical alignment required,
maximizing the convenience of instrument baseline zeroing. This design
extends maintenance intervals without loss of performance.
‣ Long path (220 mm) absorbance cells.
‣ Hg lamp electro-optical feedback beam utilizing a high-performance solidstate
detector for ultra-fine lamp stabilization.
‣ Fixed optical interference filters, three each (254 ± 2 nm wavelength, 20%
T, 12.7 mm dia.). No moving parts.
‣ Standard Perma Pure ® dryer cartridge eliminates the need for Mg(ClO 4) 2
drying agent.
‣ Stabilized double beam optics - traditional double-beam (sample and
reference) with a CCD detector.
‣ Internal ADC (Analog-to-Digital Conversion).
‣ High-rate data sampling.
‣ Computer controlled system shutdown/standby routines.
‣ Integrated optional autosamplers for accommodation of calibration
standards and up to 720 samples.
‣ Ethernet communications.
‣ Gas exhaust Hg vapor safety trap (solid crystalline KMnO 4).
