    Abstract:

    Intracavity laser quenching has been used to detect 9 x 10(7) atoms of Cs vapor. An enhancement factor of about 2000 over the sensitivity for single-pass detection is observed. Known techniques should make it possible to increase the sensitivity level to near 10(6) atoms.

    Gas Chromatography: Types of Detectors-I

    There are different types of detectors used in gas chromatography, each with its own specific properties that make it suitable for detecting certain types of analytes. The most commonly used detectors in GC are thermal conductivity detector (TCD), flame ionization detector (FID), and electron capture detector (ECD).
    TCD is the earliest and most widely used detector that operates by measuring the changes in the thermal conductivity of the carrier gas. When a sample compound enters the detector,...
