等離子體質譜純級試劑（ICP-Mass Pure Grade）:絕大多數(shù)雜質元素含量低于0.1ppb，適合等離子體質譜儀（ICP Mass）日常分析工作。
等離子體發(fā)射光譜純級試劑（ICP Pure Grade）:絕大多數(shù)雜質元素含量低于1ppb ，適合等離子體發(fā)射光譜儀（ICP）日常分析工作。
原子吸收光譜純級試劑（AA Pure Grade）:絕大多數(shù)雜質元素含量低于10 ppb ，適合原子吸收光譜儀（AA）日常分析工作。
一般化學試劑的品級：一級試劑 二級試劑 三級試劑 四級試劑
國內標準名稱：優(yōu)級純（保證試劑）、分析純、化學純 、實驗試劑
國內標簽顏色：綠色 紅色 藍色 中黃色
純度及用途：純度高質含量低，適用于研究和配制標準液； 純度較高，雜質含量較低，適用于定性和定量分析 重量略低于二級試劑，用途近似二級試劑
