Exeter Analytical has announced that it recently installed a Model 440 CHN/O/S elemental analyser at European contract analytical service laboratory - Butterworth.
Frank Judge, principal analytical chemist at Butterworth Laboratory, said: 'We have used a manual Exeter Analytical Model 440 system for some years.
'After a detailed evaluation of the commercially available instruments we decided upon a new generation Model 440 with autosampler and linear regression plus software.
'We have found that the Model 440 with autosampler has given us much tighter precision on the third percentage decimal point.
'The linear regression plus software has achieved a level of CHN accuracy and precision we have not experienced before.
'The Model 440 gives accurate, reliable results with wide ranging sample types from low level screening of inorganics for carbon right through to high levels in graphite, as well as confirmation of novel synthetic compounds,' he added.
Drawing upon wide ranging industrial sector knowledge and expertise in classical wet chemistry, spectroscopic, chromatographic and elemental microanalysis techniques, Butterworth Laboratory is able to offer routine analysis, stability testing, method development, validation, verification and other customer specific requirements.
It is Ukas accredited for CHN determination and is routinely inspected by regulatory and accreditation authorities to ensure that its quality system continues to meet the requirements for GMP, GLP and ISO17025.
