Using CHN Microanalysis To Determine Sample Purity

Exeter Analytical Inc. have produced a technical report that reviews the benefits that CHN microanalysis offers laboratories for determining sample purity by providing a precise and accurate analysis of percentage carbon, hydrogen and nitrogen content.

The report examines a range of sample types that pose problems for determining sample purity using other popular analytical techniques such as Mass Spectrometry (MS) and Nuclear Magnetic Resonance (NMR) Spectroscopy. The report describes how, with modern horizontal furnace CHN microanalysis instrumentation, precise and accurate results without constant system optimisation can be obtained for a wide range of samples types from organic compounds, through organometallic species to proteins and peptides.

The report concludes that a horizontal furnace design CHN microanalyzer, such as the Exeter Analytical Model 440, is a powerful complimentary tool to MS and NMR for analysts seeking to reliably characterise samples.

As a company dedicated to elemental microanalysis, Exeter Analytical's nearly 30 years of involvement with instruments, consumables and supplies has allowed them to better understand the whole problem facing microanalysts. As a consequence whether you are a regular or an occasional purchaser - experienced and knowledgeable staff are always available to provide free informed advice.
