Weigh about 1g of sample (accurate to 0.1mg) in a small beaker. When there is about 1cm of mixed liquid on the top of the silica gel, immediately transfer the sample in the beaker into the column with the mixed liquid, and then rinse the column with the remaining mixed liquid. At the same time, replace the first eluent collection bottle under the column with the first eluent collection bottle, and control the rinsing speed at about 20 drops/min. When the mixed liquid has all entered the column and a small amount of solution is left on the top of the silica gel, immediately rinse the column with 220mL of acetone through a separatory funnel, and replace the second eluent collection bottle under the column. After elution is completed, evaporate the solvent in the collection bottle on a hot water bath, then use ether to transfer all the residue in the collection bottle to two 50mL beakers with constant weight, evaporate the solvent in the beaker on a water bath, wipe the outer wall of the beaker dry, place it in a 105℃ oven to dry for 0.5h, transfer it to a dryer to cool for 0.5h, and weigh it.

The main drafters of this standard are Xu Shuyi, Fan Ping, Zhao Fusheng, and Jia Chunyao. 4202 According to the batch size, determine the sample size according to Table 4, and randomly select barrel samples from the batch. Table 4
Batch (number of barrels)
Sample size (number of barrels)
51～150
6.2.3 Slowly insert the glass sampling tube to the bottom of the barrel, fill the glass sampling tube with samples, cover the upper mouth of the pipette, take out, put the sample into the mixing bottle, take out similar samples from each barrel to make the total amount about 3kg, mix thoroughly, and pack them into three clean, dry containers with lids, seal them, label them and indicate: sample name, type, grade, batch number, production unit, sampling date and sampler. The samples are inspected by both parties to the delivery, and the third copy is kept by the delivery party for arbitration. The storage period is one month. 6.3 Determination of inspection results
6.3.1 Inspection of packaging quality should be carried out at the delivery location, and packaging that does not meet the requirements should be replaced. 6.3.2 The results of physical and chemical index inspections are used to determine whether the product is qualified or unqualified by the rounded value comparison method. If one index does not meet the requirements of this standard, double sampling should be conducted from the delivery batch to retest the unqualified item. If the retest results are still unqualified, the batch of products is judged to be unqualified. 6.3.3 When the delivery parties have objections to the product quality inspection results, they can negotiate to resolve the issue. If necessary, they can jointly select an arbitration agency for inspection and ruling.
