Elemental analyser claims four of the top five positions in an independent study to access current proficiency of microanalysis
In a recently published report from the Royal Society of Chemistry (MicroAnalytical Group), assessing the current proficiency of microanalysis in end user laboratories, four out of the top five laboratories used the CE440 elemental analyser from Exeter Analytical.
The evaluation exercise, that took in results from 21 laboratories equipped with CHN analysers from all the major suppliers, was essentially a repeat of previous studies run by the MicroAnalytical Group in 1997, 1994 and 1974.
The objectives of the exercise were to access current proficiency of microanalysis, to identify significant factors in achieving high accuracy/precision and to determine underlying trends in reported results.
The study concludes that the 2004 performance evaluation concurs with the previous exercises in that horizontal sample injection systems consistently have come out top in terms of data quality.
Further it was noted that the top three laboratories in the study maintained tight control of variance in sample weighing.
Designed to give accurate, reliable results, over the widest range of sample types presented for analysis the Exeter CE440 gives unmatched operating accuracy and precision, the company says.
The CE440 uses thermal conductivity detection to measure carbon, hydrogen and nitrogen, after combusting and reducing a sample.
Said to eb inherently more stable than gas chromatographic based systems the CE440 delivers superior performance and sampling precision 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.
