3 Method summary

The sample after 105 ℃ ± 5 ℃ oven dried to constant weight, measured losing quality material.

4 Instrument

4.1 Analysis of balance. a sense of the amount of 0.1mg. 4.2 flat glass weighing bottle. diameter 60mm ~ 70mm, height 35mm or less. 4.3 Electric oven. Maximum temperature range 300 ℃.

5 Sample

The sample was simple, rapid mixing, and sealed in plastic bags, used as a moisture measurement. Step 6 Analysis 6.1 Sample Weigh about 5g sample, accurate to 0.0001g. Independently carry out two measurements, the results of the arithmetic mean. 6.2 Determination The sample (see Chapter 5) placed by the 105 ℃ ± 5 ℃ constant weight of glass weighing bottle, lid, moved into an oven from room temperature 105 ℃ ± 5 ℃ maintained 2h. Remove and close the lid, moved into the dryer to cool to room temperature and weighed. Repeat dried to constant weight. Poor quality does not exceed 2mg twice before and after is a constant weight.
