| 摘要 |
The present invention relates to the detection of an analyte species. The invention provides, inter alia, apparatus suitable for use in the immunological detection of an analyte species in a gaseous medium, or the detection of a particulate species in a gaseous medium, which apparatus includes means for applying a sample containing analyte species to a carrier means (12) the carrier means being such that, in operation, the sample may be applied to a portion thereof and such that the portion may be presented to a detector (27) for detecting interaction of the sample, or a constituent thereof, with a reagent or reagents so as to permit successive analysis of samples for analyte species. The apparatus may also include means (21, 22, 23) for obtaining from the gaseous medium a sample containing analyte species, for application to the carrier. The analyte species may be, for example, an airborne species such as a drug or an environmental pollutant. |
