    摘要： A chromatographic device is disclosed. The device comprises in combination a housing, a strip of bibulous material non-removably confined in the housing. The strip 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 attached thereto for supportively confining the strip in the housing. The strip is confined so that (1) the front and back of the strip are essentially free from contact with the walls of the housing and (2) the capillary action of the strip remains substantially unchanged, and (3), where the strip is paper, the strip is allowed to expand as it is traversed by the liquid medium. The bottom end of the housing contains means for enabling contact of a portion of the strip with the liquid medium. The housing further contains means for visually observing the strip and can also contain indicating means cooperative therewith to assist in determining the result of a chromatographic test. The present device has particular application in immunochromatography for the determination of the presence of an analyte suspected of being present in a sample.
