SG是特定级,specific grade的缩写,化学试剂分为以下几种:MG(Medical grade)医药级,FA(food additives)食品添加剂,GR(guaranteed reagent)优级纯,AR(analytical reagent)分析纯,CP(chemical regent)化学纯,IND(indicators)指示剂,PT(primary reagent)基准试剂,BR(biological reagent)生物试剂,LR(laboratory reagent)实验试剂,SG(specific grade)特定级,EP(extra purity)超纯,BS(biological stains)生物染色剂。至于具体的纯度和杂质限量是怎么要求的我就不清楚了
