Maintaining High Quality CHN Microanalytical Data
Product News Jul 01, 2009
Exeter Analytical has launched a new scheme whereby customers receive free-of-charge training for the lifetime of a newly purchased Model 440 CHN analyzer.
Determining the Carbon, Hydrogen, Nitrogen, Oxygen and Sulphur content of unknowns is one of the most basic and essential needs for any chemist. Removing sources of variability from these analyzes is a critical step in ensuring data quality.
As a company dedicated to elemental microanalysis, Exeter Analytical's 25 years of involvement with CHNOS instruments, consumables and supplies has allowed them to better understand the whole problem facing microanalysts.
Exeter Analytical explains, the aim of its scheme is to empower new customers with training in every aspect of running their samples thereby enabling laboratories to routinely achieve the highest quality of data irrespective of sample type. Not only does the scheme enable new customers to get up and running as soon as possible - but the lifetime pledge covers them also if staff change. In such circumstances Exeter Analytical will retrain new users at no extra cost.
The Model 440 uses thermal conductivity detection to measure Carbon, Hydrogen and Nitrogen, after combusting and reducing a sample. Inherently more stable than gas chromatographic based systems the Model 440 delivers performance and sampling over a very wide range of elemental content.
Horizontal sample injection enables automatic removal of sample residue after each analysis, avoiding memory effects and gas flow problems.
