Warwick Analytical Service (WAS) is able to offer a routine service for precise determination of sulphur from ppm to % levels using Inductively Coupled Plasma - Optical Emission Spectrometry (ICP-OES) with good precision and accuracy. The Sulfur method is covered by the company's ISO 17025 and UKAS accreditation.
Rapid Analysis of the Sulfur Content of Inorganic & Organic Samples
Measuring Sulfur by ICP-OES measures the total sulfur, 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 sulfur content is then measured using emission lines around 182 nm..
Traditionally Sulfur 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. Offering multiple analyte analysis with excellent speed, sensitivity and large linear dynamic range.
