Abstract: A spectrophotometer for measurement of the derivative spectra of substances, comprising a monochromatic light source having a spectral bandwidth, a beam divider for dividing the light from the light source into two beams, masks separate from and positioned optically downstream from the beam divider for partially masking the beams so that the unmasked portion of each of the beams has a nominal wavelength different by a predetermined value from that of the unmasked portion of the other beam, a sample container so arranged as to receive the unmasked portions of the light beams and a detector to measure the intensities of light beams transmitted through the sample cells.

Abstract: 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.
