Which is NOT an appropriate detector for a spectrophotometer?

Question

Quizplus · Accepted Answer

Thermal conductivity is not an appropriate detector for a spectrophotometer as it measures changes in temperature rather than changes in light intensity. The appropriate detectors for a spectrophotometer include photomultiplier tube, photodiode array, charged coupled device, and phototube, as they are all capable of detecting changes in light intensity at different wavelengths.
