  • Highly sensitive and selective room temperature NH3 gas

    Jul 12, 2004 · Abstract. A new ammonia gas microsensor was developed, based on the large resistance change of an ionic conductor (CuBr) film when exposed to low NH 3 concentrations. The detection is based on specific interactions between ammonia molecules contained in the gas atmosphere and mobile copper ions in the copper (I) bromide layer.

  • Room temperature flexible NH3 sensor based on polyaniline

    Mar 01, 2021 · The test chambers of different concentrations of NH 3 were prepared by mixing different volume of standard NH 3 with air. First, the test chamber was filled with fresh air using an air pump, then a certain amount of standard NH 3 was injected into the chamber via a special airlock of the chamber using a syringe which made the NH 3 distribute evenly in the chamber.

Many of the methods described in this article can be performed as an acceptance or maintenance test, depending on conditions such as the test voltageapplied or duration of test. The objective of any diagnostic test is to identify problems that may exist with a cable - in a non-destructive way - so that preventative measures can be taken to avoid potential failureof that cable when in service. Diagnostic assessments may apply to cable systems comprising of the cable itself and the associated accessories such as splices and terminations.
