论文部分内容阅读
本栏原以家庭实验做目标的,现在对於化学品的制造拟暂时不谈,而以家庭间几种常见物品的简单检验法略予介绍。这是一种常识,对於读者是需要的。本期的“基本化学讲座”栏又齐巧讨论到“化学分析”,读者如能互相参证,当然更有益处。吾们出相当代价,购到的药物、化妆品、包装食品或其他物品里面,不免有搀假之品。这可说是司空见惯的,如果要检查出来,它的方法却也简便。譬如在化妆水、生发水或他种化妆品里面,往往搀入甲醇或称木酒精。
This column was originally designed to do the home experiment, and now for the manufacture of chemicals to be temporarily talked about, but to a few common items in the family simple test method to be introduced.

This can be said to be commonplace, but if you want to check it out, its method is simple. For example, lotion, hair water or other cosmetics inside, often mixed with methanol or wood alcohol.
