Instrument Main Specifications, Feature 3. 1 Main Specifications l Power input：1500W l Numbers of digestion hole : 36 l Temperature control range: ambient temperature－210℃ l Temperature control accuracy: ±0.2℃ l Temperature difference of hole: ±1.5℃ l Controlling temperature time: 0－24 hours l Heating block: Telfon plating graphite block 3. 2 Feature l Heating module is made of graphite block, temperature control accuracy is ±0.2℃ . l Good temperature uniformity, temperature difference of hole is ±1.5℃, ensure good digestion consistency. l Teflon (PTFE) coat prevent graphite block from eroding by strong corrosive substance and ensure its long service life. The anticorrosion design of whole structure ensure it can adapt to all kinds of wicked environment. l Corrosion resistance reduce sample contamination. l Digestion time can be adjusted, depending on sample type and digestion method.
5 l Ten heating step can be edited, rising time and stable time can be set in each heating step. For the sample difficult to digest, heating step is set flexibly and made to a method database, maintained conveniently. l Temperature control range is between room temperature to 210℃, built in overheating protector. Internal temperature measurement mode or external temperature measurement mode can be selected, temperature control accuracy is well. l According to EPA method 200.2, 200.7, 200.8, 200.9, 245.1, 365.1 and 3050B. l Calibrated Class “A” digestion tube, the sample digested can be diluted to a volume immediately without transfering. l Networking function, eight instruments can be controlled by PDA at the same time.
