Micro-Wave Digestion Model 8250

Elemental techniques such as AA, ICP-OES, ICP-MS or XRF. Most of these techniques, require the sample to be dissolved prior to analysis. As analysis techniques continue to improve and become more sensitive, an even greater emphasis is being placed on methods of  sample preparation that avoid risks of contamination.

Microwave digestion is now recognised world wide as the most robust sample prep technique for AA, ICP-OES, or ICP-MS analyses. Microwave digestion involves combining the sample matrix and acids in a pressurized container and elevating the solution past the boiling point of the acid which significantly accelerates the digestion. Given the high operating temperatures and pressures, microwave digestion can be applied to a wide range of samples particularly environmental, agricultural, soils, food, feed, pharmaceutical products to name but a few. Thus producing a fully uniform dissolved sample simply, quickly and safely.

Product Description

Micro-Wave Digestion

PG Instruments Model 8250 is our entry level Micro-Wave Digestion system which offer the preparation of  SIX OR TEN Samples each of up to 60ml at one time (other models with both larger sample volumes and sample capacity available). The 8250 has been specifically developed for use with Atomic Absorption Spectrometer, Inductively Coupled Plasma OES and Mass Spec, Flame Photometers, UV Visible Spectrophotometers, Atomic Fluorescence, XRF to name but a few.

The 8250 is simple to use, has an Administration mode, 10 pre-set analytical programs for samples such as foods, waters, agricultural products, medicines, soils, sediments, oils, biological and botanical materials and a further 255 programs for the chemist to use for his own samples.

The method of Micro-Wave Digestion is the very versatile and has been well proven. It allows variations in reagents and methodology, making it ideal for a variety of matrices and elements. The variability of this method also requires a basic understanding of digestion chemistry.
