将三氯甲烷加入到饱和的氯化钠甲醇溶液中得到的悬浮液通过玻璃毛细柱,氯化钠的微粒沉积在柱内壁上。氯化钠的表面沉积量无论在软质玻璃上还是在硬质玻璃上都大于用氯化氢气体蚀刻方法所产生的氯化钠的量,因而有利于涂渍不同极性的固定液。
The suspension obtained by adding trichloromethane to saturated sodium chloride methanol solution was passed through a glass capillary column and fine particles of sodium chloride were deposited on the inner wall of the column. The amount of sodium chloride deposited on the surface is greater than the amount of sodium chloride produced by the etching with hydrogen chloride gas, both on soft glass and on hard glass, thereby facilitating the application of fixatives of different polarities.
