Title:
METHOD OF, AND APPARATUS FOR USE IN, THE DIGESTION OF LIQUID SAMPLES
Document Type and Number:
WIPO Patent Application WO2003014706
Kind Code:
A3
Abstract:
Apparatus for digesting a liquid sample has sealed housing (18) containing a source (20) of ultra violet radiation, such as a medium pressure mercury discharge lamp, for irradiating a liquid sample being conveyed through a conduit (24) also in the housing (18). The source (20) emits ultra violet radiation, in a first frequency band, for generating ozone in the sample and in a second, lower frequency band for breaking chemical bands, and creating free radicals in the sample. The apparatus may include an analyser, such as an ion chromatograph (12) connected to the sample digester.
