Features of a detector:

The following features are indicative of the usefulness of a detector.

i)  Adequate selectivity

ii) Sensitivity and detectability

iii) A linear response to solutes over various orders of magnitude

iv) Operative within a temperature range from room temperature to at least 400ºC

v) High reliability and ease of operation

vi) Short response time that is independent of flow rate

vii) Similarity in response towards all solutes

viii) Nondestructive for solutes

ix) Noise and minimum detectable quality.
