以烧碱石棉为吸收剂,在柱上吸收样品中酸性组份,分离出不皂物直接用氢火焰检测器测定,每次测定时间3—5分钟,比化学法操作可提高效率数十倍。
Absorb the acid component in the sample on the column with the asbestos absorbent, and directly detect the non-soaps with the hydrogen flame detector. Each measurement time is 3-5 minutes, which can improve the efficiency by several times than the chemical method.
