Question

What is the difference between a concentration-sensitive and a mass-sensitive detector? Is the mass or concentration of the following detector sensitive?

($a$) thermal conductivity.

($b$) atomic emission,

($c$) thermionic,

($d$) electron captive,

($e$) flame photometric,

($f$) flame ionization.

Short answer

They differ in how they detect analyte mass or concentration. $B),c),e),f)$are mass-sensitive detectors, whereas $a$) and $d$) are concentration-sensitive detectors.

Step-by-step solution

Analyte the sample.

Mass-sensitive detectors, as their name implies, are sensitive to mass, detecting the mass of an analyte present in the sample, whereas concentration-sensitive detectors sense the concentration of the analyte that enters the detector. That is the fundamental distinction.

Find the detector consider.

$a$) Thermal conductivity detector is considered a concentration sensitive detector.

$b$) Atomic emission detector is considered a mass sensitive detector.

$c$) Thermionic detector is considered a mass sensitive detector.

$d$) Electron captive detector is considered a concentration sensitive detector.

$e$) Flame photometric detector is considered a mass sensitive detector.

$f$) Flame ionization detector is considered a mass sensitive detector.
