OVS Tube with Cal louts

OSHA Versatile Sampler
OSHA originally designed OSHA Versatile Sampler (OVS) Tubes to overcome the inconveniences of earlier methods. OVS Tubes contain a filter to trap aerosols and a two-section sorbent bed to adsorb vapors in one specially constructed glass tube. Only cleaned and verified materials are used in OVS Tubes to ensure low background interference. A flow rate of 1 L/min provided by a personal sample pump is typically used to obtain volumes ranging from 60 to 480 liters. Samples are solvent extracted and analyzed by GC or HPLC with detector

For mixed-phase sampling using a true inhalable sampler that meets ISO 7708/CEN, see IFV Pro
