Abstract |
The U.S. EPA and Research Triangle Institute, are developing a test method for the collection and measurement of acrylics from stationary source emissions both upstream from (or in the absence of) a control device, where concentrations in the parts-per-million (ppm) range are expected, and downstream from a control device, where concentrations in the parts-per-million (ppm) range are expected, and downstream from a control device, where concentrations in the parts-per-billion (ppb) range are expected. The sampling train for the collection of acrylics at high concentrations (ppm) consists of a heated sampling probe, two condensate traps in an ice bath, followed by two sorbent tubes packed with 3 grams (front) and 1.5 grams (back) of Carbopack(R) B. For collecting acrylics at low concentrations (ppb), the sampling train contains a single sorbent tube packed with 0.45 grams of Carbotrap(R) (front) and 0.45 grams of Carboxen(R) 1000 (back). |
