Document Type and Number:
Japanese Patent JP2590059
Kind Code:
B2
Abstract:
A chromatographic device (20) comprises a housing (22), a strip (24) of bibulous material non-removably confined in the housing (22). The strip (24) has a length and width only slightly less than the length and width of the inner walls of the housing. The inner walls of the housing have means for supportively confining the strip in the housing. The strip is confined so that (i) the front and back of the strip are essentially free from contact with the walls of the housing and (ii) the capillary action of the strip remains substantially unchanged, and (iii), where the strip is paper, the strip is allowed to expand as it is tranversed by the liquid medium. The bottom end of the housing has an opening for enabling contact of a portion of the strip with the liquid medium. The housing further has a slot for visually observing the strip and can also have a scale (56) and opening (58) to assist in determining the result of a chromatographic test. The present device has particular appliction in immunochromatography for the determination of the presence of an analyte suspected of being pesent in a sample.
