A powerful, straightforward method for determining sample purity

A new technical paper is available from Exeter Analytical that demonstrates how CHN microanalysis offers a powerful and straightforward method for determining sample purity by providing a precise and accurate analysis of percentage carbon, hydrogen and nitrogen content.

Laboratories tasked with characterising samples today have a wide range of analytical techniques at their disposal. However no one analytical technique can provide the full information to characterise a sample. A key aspect of sample characterisation is often determination of sample purity.

The paper examines a range of sample types that pose problems for determining sample purity using popular analytical techniques such as Mass Spectrometry (MS) and Nuclear Magnetic Resonance (NMR) Spectroscopy. Using example analyses from industrial and academic customers the authors demonstrate 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 microanalyser, such as the Exeter Analytical Model CE440, is a powerful complimentary tool to MS and NMR for analysts seeking to reliably characterise samples.
