| Summary: | allows one the flexibility of sampling at 3 5 to I 00 mL/@n and long-term limits with only negligible modifications to and starvation effects occurring at the samplers' inlet face, been designed to monitor short-term exposure limits (STEL) charcoal tube and badges are possible concentration gradients chromatograph comparisons were inconclusive. Factors which depending on the vapors being sampled. The OVM I badge has device which is capable of taking samples of gas or vapor Diffusive Badge in measuring short-term benzene exposures Diffusive badges continue to flood the industrial hygiene field conditions. It is hoped that the contents of this gas chromatograph analyses. The results of the study indicated that a) no significant concentration differences interested in the OVMI badge and for those whose line of work interference from other competing vapors, and an involve passive sampling. linear regression; and c) the results of the Tedlar baga̓s market as an alternative means to charcoal tubes for sampling maximum uptake rate. Collectively, the outcomes of this measuring organic vapors. This dual sampling rate feature might have contributed to the discrepancy between the of the Gilian TRACEAIR Organic Vapor Monitoring I (OVMI) only diffusive sampler that offers dual sampling rates for organic vapors. overestimated badge sampling rate when sampling at the OVM I badges, an SKC charcoal tube, and a Tedlar bag used for performance comparisons were highly predictable based on physical process such as diffusion through a static layer. pollutants from the atmosphere at a rate controlled by a research serve as an useful aid for those specifically research suggests that a correction factor in the badge's sampling rate might prove useful as a means of correcting for short-term overestimations when sampling for benzene under the badge housing. Side-by-side benzene STEL concentrations the charcoal tube on average by 54%, although their The objective of this research is to evaluate the performance The OVMI badge has been on the market since 1990, and is the under field conditions. In general, a diffusive badge is a were found between the badges; b) the badges overestimated were measured in a Texas Gulf Coast refinery implementing two |
