Assay Technology’s 546 High Capacity Organic Vapor Badge is excellent for all day monitoring of Organic Vapors that have high PELs (greater than 200 ppm).  The 19 hole sampling face greatly reduces the possibility that the collection media becomes saturated, making a second wafer inside the badge unnecessary in most environments.  The 8 hour reporting limits are different for each chemical, but they are about 0.5 ppm, which is well below most PELs.  Check our sampling guide for the chemical you are interested in.  The 546 badge is not usually recommended for STEL (15 minute) monitoring.

Why Prepay for the Analysis

Customers can purchase samplers with the analysis at AT Labs’ AIHA-LAP, LLC accreditated laboratories already pre-paid.  Since both the monitor and analysis is sold at the same time, the price is significantly lower than buying them separately. The -1 products come with the analysis of one chemical prepaid. The -4 products come with the analysis of up to 4 chemicals. This  satisfies most needs.

However, at times, a customer will need more chemicals than they have prepaid for. When this happens, a customer can simply request the additional chemical and will be billed for it after the report is completed.
