katharometer

A scientist uses a katharometer to analyze a gas sample.

Definition

Noun: A katharometer is a scientific instrument used to measure the thermal conductivity of a gas or gas mixture. It operates by detecting changes in the electrical resistance of a heated wire, which vary depending on the thermal conductivity of the surrounding gas.

Usage

The word katharometer is a technical term used primarily in scientific and industrial contexts, such as chemistry, physics, and process engineering. It is used to describe the specific device itself. * The katharometer is commonly employed in gas chromatography as a detector. * Researchers used a katharometer to analyze the composition of the unknown gas sample.

Examples
  • The sensitivity of the katharometer makes it suitable for detecting hydrogen in air.
  • A malfunctioning katharometer can lead to inaccurate readings of gas purity.
  • In the laboratory, the katharometer was calibrated using a standard nitrogen gas.
Advanced Usage
  • Katharometric analysis: Refers to the analytical technique that uses a katharometer.
    • Katharometric analysis confirmed the presence of helium in the natural gas stream.
Variants and Related Words
  • Katharometry (noun): The measurement or technique of using a katharometer.
    • Katharometry is a standard method for gas analysis in many industries.
Synonyms
  • Thermal conductivity detector (TCD) (This is the more common modern term for the same type of instrument.)
  • Hot-wire detector
Notes on Different Meanings

The word katharometer has a single, specific technical meaning related to the measurement of thermal conductivity. It does not have other general or figurative meanings.
