    • Subject matter of the invention is a method for detecting surface contamination by an analyte by wiping the analyte off the surface with the aid of a wiping surface, eluting the analyte from the wiping surface with an eluant, and detecting the analyte in the eluate in an immunological detection reaction, characterized in that: a) the surface to be tested for the analyte is wiped with a wiping surface, b) the wiping surface is brought into contact with the planar surface of a capillary active, chromatographic test strip which has an eluant application zone at its one end and a target zone at its other end whereby contact is made in an area between these two zones, c) eluting liquid is applied onto the zone provided for this purpose, said liquid moving toward the target zone passes the contact site with the wiping surface as a consequence of capillary forces, whereby analyte is taken up by the eluant, and d) in the target zone, the analyte is measured in an immunological binding reaction. The method is particularly suitable for the detection of drugs on surfaces.
    • 本发明的主题是通过擦拭表面擦拭分析物离开表面的方法,用分析物检测表面污染物的方法,用洗脱液从擦拭表面洗脱分析物,并用洗脱液检测洗脱液中的分析物 免疫学检测反应,其特征在于:a)待分析物的表面用擦拭表面擦拭,b)擦拭表面与具有洗脱剂的毛细管活性色谱测试条的平面接触 在其一端的应用区域和其另一端的目标区域,由此在这两个区域之间的区域中进行接触,c)将洗脱液施加到为此目的设置的区域上,朝向目标区域移动的所述液体通过接触 作为毛细管力的结果,由于分析物被目标区域中的洗脱液和d)吸收,所以在免疫结合反应中测量分析物。 方法特别适用于检测表面上的药物。
