SVDV is a configuration used in ICP-OES instruments that enhances the analytical capabilities of the technique. In traditional ICP-OES, the sample is aspirated and atomised within the inductively coupled plasma, and the emitted light is collected by a single optical path and passed through a single optical grating system to measure the emitted spectra.
SVDV introduces two simultaneous views (axial and radial) of the plasma emission, which provides distinct advantages: Axial view is optimised for the detection of low concentration elements and trace metals, providing a longer path length for the emitted light, increasing sensitivity for trace analysis and Radial view which measures high concentration elements and major components. It provides higher spectral resolution and lower background noise for elements that emit strong signals. SVDV-ICP-OES is a technique used for the detection of elements at trace (parts of million) levels in numerous sample types, which provides a highly reliable technique due to good stability, limited spectral interferences and low matrix effects.
Atomic Absorption Spectroscopy (AAS) is a sensitive and selective technique designed for the quantitative determination of metallic elements within a sample. By measuring light absorption at element-specific wavelengths, AAS delivers quantitative accurate and reproducible results across a wide range of sample types. It is a proven, industry standard approach for elemental analysis in pharmaceutical and life science applications, including complex and organic solvent matrices.
AAS supports regulatory driven testing for Assays and elemental impurities in line with regulatory and pharmacopeial requirements. The technique offers high sensitivity combined with strong elemental selectivity to ensure reliable results covering a range from % to ppb. Its flexibility enables efficient testing of raw materials and finished products while rapid, consecutive analysis supports streamlined QC and R&D workflows in regulated environments.
RSSL offers a comprehensive suite of Atomic Absorption Spectroscopy (AAS) techniques to support routine and trace elemental analysis across Food, Pharmaceutical and Life Science applications.
Using Flame AAS for efficient ppm-level testing, Graphite Furnace AAS for enhanced ppb-level sensitivity in complex matrices, Hydride Generation AAS for high-performance analysis of elements such as arsenic and selenium, and Cold Vapour AAS for ultra-trace mercury determination, our capabilities deliver accurate, selective and regulatory-ready results across a wide range of sample types.
