GB/T 6682-2008 analytical laboratory use specifications and test methods (ISO 3696. 1987, MOD)
3 Method summary
Sample is placed in a weighing bottle, at 180 ℃ ± 5 ℃ electric oven dried to a constant mass in order to reduce the mass of the sample is calculated
Moisture content.
4 General Provisions
This part of the reagents and the water did not indicate when the other requirements are specified analytical reagent refers to 6682-2008 and GB/T 's
Three water.
5 instruments and equipment
5.1 electric oven. the temperature can be controlled at 180 ℃ ± 5 ℃;
5.2 weighing bottle. diameter 50mm, height 30mm.
Step 6 Analysis
Weigh about 2.0g sample, accurate to 0.0001g. Has been placed at 180 ℃ ± 5 ℃ drying to constant mass weighing bottle immediately cover
On weighing bottle, the weighing bottle was placed in the electric oven, weighed on the weighing bottle caps oblique. The temperature of the electric oven
Low temperature was gradually raised to 180 ℃ ± 5 ℃, and incubated 2h. Open electric oven, immediately close the weighing bottle, moved into the weighing bottle and dried
Vessel, place 40min after weighing. Re-weighing bottle into the electric oven, the weighing bottle diagonally on the weighing bottle in
180 ℃ ± 5 ℃ baking 1h, covered weighing bottle immediately removed, placed in a dryer placed after 40min weighing. Repeat this step until Quality
Constant.
7 Results Calculation
Moisture mass fraction w1 and its value is expressed in%, according to equation (1).
