Proximate Analysis of Biomass

Sample Preparation

Crush & Grind the sample to size ≤ 1mm, then insert the sample into furnace under 815℃ to burn completely ,then grind the ash to the size ≤ 0.1mm

Instrument

5E-MAG6700 Proximate Analyzer - TGA

Instrument Settings

Set the temperature of M/VM/A in software before analysis;

Set the keeping time of M/VM/A in software before analysis;

Set the temperature rising speed of VM/A in software before analysis;

Special Modifications to Unit

None

Procedure

1. Weigh 0.6g±0.1g for Moisture and Ash in M&A part according to the instruction manual. Make sure sample in crucible is flattened before you start analysis.

2. Weigh 0.6g±0.1g for Moisture and Ash in VM part according to the instruction manual. After sample weighing, cover the lid on crucible.

3. click start , results will be given automatic after analysis.
