Densitometer for quantitative determination of the content of a sample spot on a TLC plate or the like, wherein dualwavelength zigzag scanning is conducted on the spot. Light reflected and transmitted by the sample is received by photometers, and compensation based on Kubelka-Munk's theoretical equations is made on the photometer output so that the output is substantially proportional to the quantity of the substance in the spot being scanned. |
