3M monitors are made to allow sample desorption directly in the monitor itself. The monitor comes with a snap-on elution cap that permits the desorbing solvent to be injected into the monitor. The solution is then poured into sample vials for analysis. 3M monitors use standard analytical methods: gas chromatography for the organic vapor monitor and ethylene oxide monitor, and colorimetry for the formaldehyde monitor.
