Abstract

This invention relates to devices for providing vapour samples of volatile components of a solution and apparatus for allowing such samples to be tested. Two different sample containers (10 and 52) are described. In each, a volatile solution is retained so that the volatile component equilibrates with a headspace from whence it can be drawn off into testing apparatus. In the device (10), the volatile component is retained by a gas-permeable-hydrophobic membrane (14), whilst in the device (52) the solution is retained in absorbent material (56). The device (10) has associated apparatus (26), whilst the device (52) is complete in itself. In each case, when the testing apparatus is located on a sampling outlet port, it causes a valve to open allowing sampling to occur.
