Industry news

Warwick Analytical Service (WAS) now offers a routine service for precise determination of sulfur from ppm to % levels using Inductively Coupled Plasma - Optical Emission Spectrometry (ICP-OES). The Sulfur method is covered by the company's ISO 17025 and UKAS accreditation.

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 nebulizer 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.

Atomic Absorption / Emission SpectroscopyAtomic absorption spectroscopy (AAS) and atomic emission spectroscopy (AES) — also called optical emission spectroscopy (OES) — are used to detect the elemental constituents in samples. Both techniques involve the atomization of a sample. Atomic absorption spectrometers may use a flame or furnace to create an atomic vapor of the sample before irradiation with spectral light. Optical emission spectrometers may use a flame, inductively coupled plasma (ICP), microwave plasma (MP) or spark arcs to atomize and excite the sample. At higher excitation energies, electrons can be emitted instead of photons, which can be useful for samples that can’t be atomized and for surface analysis. Explore electron spectroscopy equipment such as Auger spectrometers and photoelectron spectrometers for surface elemental analysis of samples.
