以硅胶或氧化铝的薄层层析已被广泛用于农药残留量、水质、食品及生化样品中有害物质的分离和测定,但一般的薄层板存在有下列一些缺点:(1)制成的薄层板非常脆弱,只能使用一次;(2)每次需制薄层板,硅胶或氧化铝的消耗量大,对于人力物力都不经济。奥村保等首先提出了用玻璃粉与氧化铝或硅胶可以按各种不同比例混合制成烧结薄层板,此板不仅具有普通薄层板的优点,而且便于携
Thin-layer chromatography with silica gel or alumina has been widely used for the separation and determination of harmful substances in pesticide residues, water quality, food and biochemical samples, but there are some disadvantages of conventional thin-layer plates as follows: (1) Of the thin plate is very fragile, can only be used once; (2) each need to be made of thin plates, silica gel or alumina consumption, for human and material resources are not economical. Okumura Paul first proposed the use of glass powder and alumina or silica gel can be mixed in various proportions made of sintered laminates, this board not only has the advantages of ordinary laminates, but also easy to carry
