Warwick Analytical Service has announced the availability of an analytical service note describing its testing methods for micro-determination of sulphur.
The analytical service note, available at Warwick Analytical Service's website, has been set up to give scientists information on a range of commonly used laboratory analytical testing methods.
Each PDF note includes a background to the laboratory analytical test, typical sample requirements, an overview of the analytical methodology used and typical results achievable by Warwick Analytical Service.
The analysis of sulphur is carried out by combustion of an accurately weighed sample in a silica oxygen flask over an accurately measured volume of aqueous peroxide solution.
Combustion of the sample in oxygen yields water-soluble inorganic compounds.
Percentage sulphur is determined by titration with barium perchlorate using thorin screened with methylene blue as an indicator.
Sets of work typically include certified reference materials or organic analytical standards to monitor detection trends in the method.
Operating in an ISO 17025 and GMP accredited environment, Warwick Analytical Service 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 sulphur.
From extensive method validation typical results are within the +/- 0.3 per cent absolute limits considered acceptable for micro-chemical analysis.
The Warwick Analytical Service method has been fully validated and is linear from 0.006mg to 1mg sulphur.
The company has developed special procedures to remove interferences from samples containing fluorine, chromium, arsenic and metals.
The accurate micro-determination of sulphur in organic and inorganic compounds is of interest to an array of industries including chemicals, petrochemicals, pharmaceuticals, biotech, environmental monitoring and geochemistry.
