    • The invention relates to a device for preparing the qualitative and quantitative analysis of substance spots on a ductile thin-film plate (1) using thin-film chromatography. The device has a rinsing head (2) which can be placed on the thin-film plate (1), the latter being coated with the dried sorbent (4) and which is provided with a projecting, closed ring cutter (3) by which means the sorbent (4) can penetrate as far as the top surface of the thin-film plate (1) and be sealed against the surrounding sorbent. At least one supply line to the cavity (5) formed inside the ring cutter (3) is connected to the rinsing head (2). An elution liquid for eluting the substance making up the substance stain can be introduced through said cavity.
    • 本发明涉及一种设备,用于制备物质污渍的定性和定量分析在所述薄层色谱延性薄板(1)。 该装置包括一个清洗头(2)中,涂布在(4)的薄板(1)设置有附连的突出,封闭轮缘切割干燥的吸附剂(3)与该吸附剂(4)到顶部 薄板(1)能够被穿透并相对于周围吸附剂密封。 此外,供给线到轮辋边缘(3)形成的空腔(5)的内部被连接到所述冲洗头(2)至少通过一个物质洗脱,贴片洗脱液体的物质被引入。
