Warwick Analytical Service (WAS), the analytical division of Exeter Analytical (UK), has further refined its accurate method for the automated micro-determination of chlorine and bromine.
Offered by WAS as an analytical service, the determination of individual or mixed halogens (chlorine and bromine) is carried out using a single automated titration analysis.
Operating in an ISO 17025- and GMP-accredited environment, WAS has developed proprietary analytical procedures to enable accurate and precise data to be produced for all types of samples, including samples with trace levels of halogens.
From extensive method validation, typical results are within the +/-0.3 per cent absolute limits considered acceptable for micro chemical analysis.
Rebekah Vine, laboratory manager, said: 'While techniques such as ion chromatography offer ease-of-use benefits, they cannot match the accuracy and precision achievable by our titration methods.
'Titration plays a key role in sample testing in many industries and, although manual tests provide good levels of accuracy, it is labour intensive and time consuming.
'Typically, manual titration offers no means of ensuring total consistency in analyses between different analysts.
'Our auto-titration service eliminates this source of error,' she added.
