NJbinglab Graphite Digestion System, Made To Order, For ICP-MS

Ürün detayları

1. Product Introduction. The graphite digestion system is a very representative hole-type digestion device that uses graphite blocks as heat-conducting media. It heats the sample in a surrounding heating method, effectively increasing the utilization rate of thermal energy. At the same time, it occupies the front end of conventional digestion equipment with its advantages of higher temperature control accuracy, small differences between holes, efficient digestion, energy saving and environmental protection. 2. Application Cases. 1. Weigh 25ml of water sample, put it into a 50ml PTFE digestion tube, and shake it well. 2. Put the sample tube into the graphite digestion instrument for digestion. 3. After the digestion is completed, put the fixed volume sample on the machine for detection. (Sample addition: 2ml nitric acid; heating: temperature 140 degrees Celsius, heating time 20min, holding time 2h; cooling: 5min; fixed volume: 25ml.). Parameters: Model: XJ-24R. Temperature control: range Room temperature-220 degrees Celsius. Temperature control: accuracy 0.1 degrees Celsius. Heating material: High-quality graphite + Teflon anti-corrosion coating. Number of sample holes: 16, 24, 36, 48, 54, 63, 100 (can be customized according to customer requirements). Control and display mode: PID temperature control digital display. Power supply: 220v/50Hz.
