Warwick Analytical Services is providing a routine service for precise determination of sulphur.
WAS determines sulphur from ppm to % levels using Inductively Coupled Plasma - Optical Emission Spectrometry (ICP-OES).
Measuring sulphur by ICP-OES measures the total sulphur, both organic and inorganic.
Due to the sensitivity of the technique a broad range of sample weights can be used making the method applicable to a wide cross section of samples.
The sample is digested, typically using microwave digestion. The sample solution is then passed though a nebuliser and aspirated into the plasma.
The sulphur content is then measured using emission lines around 182 nm. Traditionally sulphur is measured by a variety of methods many of which are time consuming and suffer from interferences.
However using ICP-OES can provide a rapid analysis with simple sample preparation.
