Hole digester with 36 holes or 48 holes can be used for atomic absorption spectrometry---Nanjing Binglab

Graphite digester is one of the direct, effective and economical sample pretreatment methods for elemental analysis.


Graphite Furnace Atomic Absorption Spectrometry Method


1.Product introduction

Graphite digester is a representative hole-type digestion device, which uses graphite block as heat conduction medium. It heats the sample with a surrounding heating method, which effectively increases the utilization rate of heat energy. At the same time, it occupies the front end of conventional digestion equipment with the advantages of higher temperature control accuracy, small difference between holes, high digestion efficiency, energy saving, and environmental protection.


2. Application case

Ø Weigh 25ml of water sample, put it into a 50ml polytetrafluoro tube, and shake well.

Ø Put the sample tube into the graphite digestion apparatus for digestion.

Ø After the digestion is completed, the sample will be fixed and tested on the machine.

(Sample addition: 2ml nitric acid; heating: temperature 140°C, heating time 20min, holding time 2h; cooling: 5min; constant volume: 25ml.)


3.Parameters of graphite digester

Package product PTFE digestion tube, PFA digestion vessel

4.Advantages of graphite digester

Advantage 1: High temperature resistance, acid and alkali resistance and organic solvent corrosion, good stability;

Advantage 2: The speed of digesting samples is fast, and samples can be processed in batches;

Advantage 3: Fully enclosed design, while preventing heat loss to a great extent, it can also effectively avoid the intrusion of acid mist and damage to equipment components;

Advantage 4: Clean and corrosion-resistant: using a special spraying process, the coating is uniform, firm, and will not fall off after long-term use;

Advantage 5: Efficient: Adopt advanced integrated surround heating method, all parts of the sample are heated evenly, and the digestion is fast and thorough;

Advantage 6: Convenient operation, environmental protection and energy saving, saving economic cost;

Advantage 7: PID temperature control system, excellent performance, high temperature control accuracy, up to ±1°C;

Advantage 8: The heating rate can be adjusted, the temperature can be programmed to rise and the heating holding time can be controlled, and the heating rate is stable.


We advocate safe, healthy and efficient experiments!
