# AnalyticalCard: A chromatography card used for drug testing.
pad:AnalyticalCard a owl:Class ;
    rdfs:label "Analytical Card" ;
    rdfs:comment "A record of a PAD card as imaged after development. The physical card is typically 3″ x 4″, printed with wax barriers forming 12 lanes, with reagents pre-applied below the swipe line; a sample (drug) is applied and the card developed by immersing its lower edge in water, so the reagents react to produce a Color Barcode used for identification. The physical card is identified by its QR number, carried here as hasSampleId. A developed card is usually imaged several times - under different lighting and on different devices, to make downstream models robust - so several records normally share one QR number and differ in their capture details (hasCameraUsed, hasCreationDate, hasRawImage, hasProcessedImage)." ;
