Ultra Passive Samplers - The passive alternative for ppb level VOCs

Ultra I - Prefilled for ppb-level detection

Patented SKC Ultra Passive Samplers provide reliable sampling of low level volative organic compounds (VOCs) without the use of a pump. Target chemicals diffuse from the atmosphere into the sampler at a fixed rate. Analysis is by highly sensitive thermal desorption with gas chromatography (GC)
