A photometer simply measure the total lumens of a light source, while a spectrophotometer will measure a whole spectral of that same light source. Hence a spectrophotometer will give us more details...
The difference is complexity. Either may be used for quantitative or absorbency purposes depending on the situation. Also of note, each may have a single or double beam integrated into it. For...
Colorimeters and photometers use filters to obtain a monochromatic light. Spectrophotometers use a monochromator (prism or grating). Of course, a spectrophotometer is a more advanced, accurate and...
The UV/Vis passes light through the sample, measuring the light the sample absorbs; the AA aspirates the sample by exciting the molecules at a specific wavelength that allows you to measure only the...
