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 organic samples with trace
levels of Fluorine.
From extensive method validation typical results are within the ±0.3% absolute
limits considered acceptable for micro chemical analysis. The WAS method can
detect 0.01ppm fluoride which is equivalent to 0.02% in a 10mg sample.
WAS has developed special procedures to remove interferences from samples
containing boron, calcium or sulfur.
Offered by Warwick Analytical Service (WAS) as an analytical service, analysis
of Fluorine is carried out by combustion of an accurately weighed sample in a
silica oxygen flask over an accurately measured volume of water and TISAB
buffer solution. A fluoride ion selective electrode is used to directly
measure the potential of a range of fluoride solutions. The potential of
the combusted samples are measured under the same conditions. The
concentrations of the sample solutions are calculated from the derived
calibration curve. Sets of work typically include certified reference materials
or organic analytical standards. Results from these standards and the
electrode response are monitored to detect trends in the method.
The accurate micro determination of fluorine in organic compounds is of
significant interest to a wide array of industries including food and
beverages, environmental monitoring, medical, pharmaceutical and polymers.
Warwick Analytical Service (WAS) is a company dedicated to providing analytical
excellence at a realistic cost. Through experienced staff, the latest
