909 UV digester is an advanced digestion equipment that can preprocess samples through UV photolysis. Organic molecules in the sample can interfere with the measurement of heavy metals, especially for voltammetry and spectrophotometry based measurementsICPandAASMeasurement interference is significant. Based on validated ultraviolet technology, the new model909 UVUV digesters can effectively eliminate organic components in liquid samples and provide fast and concise sample pretreatment, especially for easily handling highly contaminated samples.
909 The UV digester is capable of fully automatic digestion of samples. Its core component is the ultraviolet lamp, which can provide the necessaryUVRay. The air cooling system can eliminate the heat generated by ultraviolet lamps. In order to ensure that the UV digester can operate under controlled conditions, during the sample testing processPt1000The temperature sensor measures the digestion temperature. Embedded microprocessor controls digestion temperature and time.

The relevant standards for sample pretreatment using ultraviolet photolysis include:
• DIN 38406，Part 16Detection of Zinc, Cadmium, Lead, Copper, Thallium, Nickel, and Cobalt by Voltammetric Polarography
• DIN 38406，Part 17Determination of uranium in surface water, raw water, and drinking water by adsorption stripping voltammetry
