Answer #1

An IR detector is not used in HPLC..

Before that lets see what are the ideal properties of the detector used for HPLC

  • high sensitivity, good stability and reproducability
  • A linear response to solute
  • negligible base line noise
  • should be inexpensive
  • capable of providing information on the identity of the solute
  • A short response time independent of the rate of flow
  • high reliability and ease of operation
  • It should be non destructive and independent of mobile phase composition
  • Temperature range from room temperature to atleast 400 degrees

Infrared detectors are used in military and civilian purposes.Millitary applications include target acquisition and surveillance,night vision and tracking and civilian purposes include scientific observations

All the other detectors are used in HPLC
