美国药典-重金属检查方法里的一段内容:
Procedure— To each of the tubes containing the Standard Preparationand the Test Preparation,add 2mLof pH3.5Acetate Buffer,then add 1.2mLof thioacetamide–glycerin base TS,dilute with water to 50mL,mix,allow to stand for 2minutes......
译文:

操作—向每一个管子内加入pH值3.5醋酸盐缓冲液2mL,然后加入硫代乙酰胺-甘油溶液1.2mL,以水稀释至50mL,混匀,静置2分钟.....

请问这里的thioacetamide–glycerin base TS(硫代乙酰胺-甘油)如何配制?操作方法在哪有说明呢?

Thioacetamide TS —Dissolve 4 g of thioacetamide in 100 mL of water.

Glycerin Base TS —To 200 g of glycerin add water to bring the total weight to 235 g. Add 140 mL of 1 N sodium hydroxide and 50 mL of water.

Thioacetamide–Glycerin Base TS —Mix 0.2 mL of thioacetamide TS and 1 mL of glycerin base TS, and heat in a boiling water bath for 20 seconds. Use the mixture immediately.

请问Glycerin Base TS 中的base如何翻译,是碱性吗

加了140 mL of 1 N sodium hydroxide,应该是碱性的吧,我把Glycerin Base TS 翻译成甘油碱试液了
