Warwick Analytical Service can investigate and precisely measure the percentage carbon, hydrogen and nitrogen content of samples with an accuracy of better than +/-0.3% for a wide range of samples
CHN analysis provides a quick and inexpensive method to check sample purity, and in conjunction with mass spectrometry and NMR data, can be used to characterise a compound.
Samples (0.5-2.0mg per analysis) are analysed using two Exeter Analytical CE 440 instruments.
This model of analyser has been demonstrated to be number one in terms of accuracy and precision in recent independent studies performed by the Royal Society of Chemistry (Micro Analytical Group).
All samples are weighed using the latest ultra microbalances.
Warwick Analytical Service's method for the determination of carbon, hydrogen and nitrogen is covered by Ukas ISO17025 accreditation.
Warwick Analytical Service (WAS) have the experienced staff and instrumentation to provide a fast, accurate and precise CHN service for a wide range of sample types, including polymers and volatile samples.
Analysis of air sensitive compounds can be reliably performed as the sample is prepared and completely sealed in a high specification glove box prior to analysis.
