Graphite digester for tetra-acid digestion method Atomic fluorescence atomic absorption...

Sample Preparation - Graphite Digestion Apparatus

Graphite digestion instrument is one of the direct, effective and economical sample pretreatment methods for elemental analysis. The application of new digestion technology has the advantages of rapid heating, program control, complete digestion, and temperature equilibrium. Graphite digestion is often used in sample preparation for atomic absorption, atomic fluorescence, ICP, ICP-MS, polarography, etc.

​7 major advantages make sample pretreatment no longer difficult

1. Fully enclosed design, which greatly prevents heat loss and effectively avoids the invasion of acid mist

2. High-quality graphite three-dimensional wrapping heating, the sample is heated evenly

3. Unique spraying process, the coating is uniform, firm, and will not fall off after long-term use

4. The digestion speed is fast, the efficiency is high, and the samples can be processed in batches

5. PID temperature control system, excellent performance, high temperature control accuracy, temperature difference ± 1 ℃

6. Easy operation, environmental protection and energy saving, cost saving

7. Split type: The controller can be placed outside the fume hood to reduce acid gas corrosion and have a longer service life
