| 摘要 |
This invention relates to a device for the simultaneous qualitative or quantitative determination of several analytes in a liquid sample, comprising a membrane ( 2 ) with a charging zone ( 5 ), for the application of the liquid sample, at least two indicator zones which can interact with the analyte(s) and at least one absorption region ( 3 ), which accepts the fluid after passing through the indicator zones, whereby the indicator zones lie between the charging zone ( 5 ) and an absorption region ( 3 ), characterized in that the flow directions (flow tracks) are essentially parallel from the application zone ( 5 ) through each indicator zone to an absorption region ( 3 ) and at least two different flow tracks are present. The invention further relates to a method for the determination of several analytes or derivatives thereof in a liquid sample, comprising: application of the sample to the charging zone ( 5 ) of a membrane of the device as given in claims 1 to 8, whereby said sample is present in sufficient amounts to permit the sample fluid to flow in the direction of the absorption region ( 3 ) through the indicator zones and to permit the analytes or derivatives thereof in the liquid sample to form a complex in the indicator zone.
