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.  While the 8-hour reporting limits are different for each chemical, they are generally around 0.5 ppm, which is well below most PELs.  For specific information about your chemical of interest, check our Sampling Guide.  The 546 badge is not usually recommended for STEL (15-minute) monitoring.

Why Prepay for the Analysis?

Saves You Time and Money

Customers can purchase samplers with the analysis at AT Labs’ AIHA-LAP, LLC accredited laboratories already prepaid.  Since both the monitor and analysis are 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, while the -4 products come with the analysis of up to 4 chemicals prepaid. These two choices satisfy most customers’ needs.

At times, customers will need analysis for more chemicals than they have prepaid for. When this happens, they can simply request the additional chemical on the lab request form and will be billed for it after the report is completed.  The price will vary depending on the type of analysis, but you can search for your chemical on our Sampling Guide to view analysis costs. Once you’ve found your chemical, expand its information by pressing the “+” button; the analysis cost for an additional chemical should be listed on the “Analysis Price, Same Test Group, 2nd Chemical” line (Hint: the item code will end with an X, e.g. A705-X).  You can also view our Price List to determine the price per extra chemical.  If you need any help determining pricing, feel free to contact our customer service team.
