The QuickTrace™ M-7500 Cold Vapor Atomic Absorption mercury analyzer is ideal for low ppt to sub-ppm mercury quantitation. The QuickTrace™ M-7500 is designed for routine use in a variety of settings, including environmental laboratories, industry, and research institutes, for virtually any aqueous acidified sample.

The QuickTrace™ M-7500 mercury analyzer easily achieves the trace mercury detection limit of < 1.0 ppt demanded by customers employing performance based EPA method 245.7. The QuickTrace™ M-7500 is also versatile enough to analyze samples > 500 ppb without dilution. The QuickTrace™ M-7500 is used throughout the world to analyze samples in the broad spectrum of mercury samples from clinical / biological to seawater samples. Some of the common applications include water and waste-water, soil and sediment, and biological tissues and fluids. The QuickTrace™ M-7500 is capable of switching between low ppm and ppt analysis without hardware or tubing configuration changes. Using the proven and reliable cold vapor atomic absorption (CVAA) technique combined with peltier stabilized detectors and multi-tasking Windows-based QuickTrace™ software package, the QuickTrace™ M-7500 is the most stable and sensitive mercury absorbance analyzer available today. For low level ppt analysis we recommend our autosampler enclosure (ENC-500) to protect the samples from determinate errors such as dust particles. The ENC-500 will also protect your investment from the harsh acid gases normally present in and around digested samples.

Testimonials

“The M-7500 mercury analyzer is everything as advertised. I am particularly impressed with its reliability. Our unit is 2½ years old and aside from pump tube replacement and cleaning the GLS we have not had any problems. The performance today is as good as the day it was installed.”
Robert Porter - Nassau County Department of Health, Hempstead,  NY

“From my experience, CETAC has not only excelled in developing a quality analyzer, but also has created the most user-friendly software around.  On top of this, their customer care is second to none.  I wish all of my instruments came with the same satisfaction that the M-7500 has delivered.”
Kent Krieg - Chemist - Analytical Services Division, SC Department of Health and Environmental Control, Columbia, SC

"I cannot say enough good things about CETAC's service and support. They are always quick to respond when there is a problem and the ease of maintenance on the CETAC M-7500 means we are able to fix most of the problems without having to send the instrument in for repair."
Troy Goehl - Microbac Laboratories, Inc., Merrillville, Indiana

Performance

Excellent short and long term stability are found in our QuickTrace™ M-7500 CVAA analyzer. Less than 0.5 ppt instrument detection limits are typical for the QuickTrace™ M-7500 utilizing less than 10 ml of sample. We consistently achieve instrument detection limits of less than 0.3 ppt utilizing less than 3 minutes of total analysis time per sample.

• Sub-ppt detection limits (< 0.5 ppt IDL)
• Linearity greater than 4 orders of magnitude
• Dynamic range < 0.5 ppt to > 500 ppb
• Without employing our smart rinse technology the system is ready to accurately measure a sample within four minutes following the ingestion of a 1 ppm sample
• < 2% RSD short term precision (5 samples @ 5 ppt)
