    摘要: Disclosed herein are methods for measuring the concentration of volatile air treatment chemicals in the air. These methods can be used to evaluate the effectiveness of, and/or optimize, dispensers that dispenses a volatile air treatment chemical into a test area. One runs side by side sampling of air using both sorbent tube and solid phase micro extraction fiber collectors to develop a correlation curve between air treatment chemical concentration results from the sorbent tube sampling and amount readings from the SPME sampling. One then uses SPME collectors to measure in a passive manner the performance of the volatile dispensers.

    摘要: Disclosed are dispensers for volatile materials. There is a container in the form of a well having an internal cavity, a volatile chemical positioned in the cavity, and a multi-layer covering enclosing the cavity. The covering has a lower section that is gas permeable, and an upper section removably bound to the lower section that is not. Embodiments include when (a) the lower section has a top layer that is a blend of high density polyethylene and low density polyethylene; the upper section has a bottom layer that has a mixture of polypropylene and a propylene/ethylene copolymer; and/or the lower section has an upper layer that has low density polyethylene but the lower section does not contain ultra low density polyethylene. These features help prevent premature leakage at the bond between the upper section and lower section.
