A porous collection disk supports the matrix and closes a lower end of a wall of the cartridge. The collection disk being sandwiched between the lower end and a base cap. An air channel extends between a first air opening at a top end of the cartridge and a second air opening positioned above the collection disk and opposite a base cap air opening. The collection disk is between the second air opening and the base cap air opening. At least one of the first air openings and the base cap air opening comprises a connection to a supra-atmospheric or subatmospheric pressure air source. The second air opening and the base cap air opening guide an air flow to provide evaporation and analyze concentration at specific locations of the collection disk, thereby improving detection limits."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Sensor cartridge for chemical assays of a liquid sample containing analyte molecules","description":"A sensor cartridge contains a porous matrix for passing analyte molecules of a liquid sample.
