Getting to Know Leeman Labs CVAFS and Direct Analysis Combustion Mercury Analyzer

Posted by Betsey Seibel on Jan 18, 2016 11:30:00 AM

Teledyne Leeman Labs offers a family of fully automated mercury analyzers that address the analysis of solids, semi-solids and liquids. Our high performance instruments help lab technicians, chemists and lab managers to complete the myriad of task required in today’s modern laboratories.

 

We recently released a Practical Guide for Selecting the Best Technique for Mercury Measurement where we describe in detail each of our mercury analyzers and how they work. In a previous post, we covered our two CVAAS systems. Below is a summary of the information included in the guide about Leeman Lab’s Cold Vapor Atomic Fluorescence Spectroscopy and Direct Analysis Combustion systems. The complete guide can be downloaded at TeledyneLeemanLabs.com.

How to select the Hg technique for your analytical needs (Part I)

Posted by David Pfeil on Feb 10, 2012 1:30:00 PM

 

Selecting the right Hg technique really depends on your analytical needs. For some labs, the decision will be driven solely by the need to comply with a specific regulatory method. For example, if your lab is required to analyze samples using EPA Method 245.1, then you will need to use the technique of cold vapor atomic absorption spectroscopy (CVAAS). If you are required to follow specific regulatory methods, you may find the following information helpful.
