    摘要: A method of operating an electrochemical gas sensor includes: a) exposing, for a first predetermined duration, the electrochemical gas sensor to an atmosphere containing a target gas while the gas reaction capability of the electrode assembly is substantially reduced from a working level, such that target gas is collected within the housing; b) increasing the gas reaction capability of the electrode assembly to a level at which it consumes collected target gas and thereby outputs a signal to the sensing circuit, including an initial transient decay signal; c) monitoring the transient decay signal; and d) analysing the rate of decay of the transient decay signal to determine whether the performance of at least one component of the electrochemical gas sensor is within acceptable limits. An apparatus for operating an electrochemical gas sensor, adapted for connection to an electrochemical gas sensor via a sensing circuit for control thereof, can carry out the disclosed method(s).

    摘要: Mannitol in certain weight percentages can be used to produce lyophilized beads of consistent size, consistent morphology, and reduced moisture content. These mannitol-containing lyophilized beads are useful in a variety of biological applications where precise reagent amounts are required or moisture-sensitive components are utilized. PCR technologies represent one biological application where mannitol-containing lyophilized beads can be used.
