ORBO sorbent tubes (W,W,W separators, O.D. × L 7 mm × 110 mm) contain two beds of the same selective adsorbent separated by glass wool or foam, for gas and vapor sampling. The dual-layer or two-bed construction of the tube allows for any sample breakthrough to be captured in the smaller back-up bed.

Giornale italiano di medicina del lavoro, 10(4-5), 201-205 (1988-07-01)
A laboratory study, using generated atmosphere containing 0.14/23.3 mg/m3 of Benzene, was conducted to adapt an existing industrial hygiene monitoring method for measuring low concentrations of Benzene. This method was developed to determine concentrations of Benzene in the ambient air
In-community non-invasive identification of asthma-specific volatile organic compounds (VOCs) in exhaled breath presents opportunities to characterize phenotypes, and monitor disease state and therapies. The feasibility of breath sampling with children and the preliminary identification of childhood asthma markers were studied.
La Medicina del lavoro, 81(2), 107-118 (1990-03-01)
Benzene is a widely diffuse solvent (atmosphere, cigarette smoke, some foods); in the industrial environment benzene is currently present at concentrations of ppm. A valid method of biological monitoring that is easy to perform is needed for assessing occupational and

Benzene concentrations in urine samples (Cu, ng/L) from 110 workers exposed to benzene in chemical plants and gasoline pumps were determined by injecting urine supernate into a gas chromatograph. The urine was saturated with anhydrous N2SO4 to facilitate the passage
The construction and testing of a unique instrument, the Paleobiosphere, which mimics some of the conditions of the ancient earth, is described. The instrument provides an experimental testing system for determining if certain microbes, when provided an adequate environment, can
