Measurement of low concentrations of halothane in the atmosphere using a portable detector
A Leakmeter, available from Analytical Instruments Limited, designed for detection of low concentrations of volatile halogenated hydrocarbons in industrial situations, proved suitable for measurements of halothane in the atmosphere. The Leakmeter consists of three components, an electron capture detector housed within a handpiece and fitted with a probe, a control unit which processes the signal from the detector and displays the output on a meter, and an argon carrier gas supply. The power supply is either mains or rechargeable battery operated. The whole instrument is compact and easily portable.
