Abstract
Apparatus for monitoring chemical reactions occurring on a slide, cartridge or other reflective carrier in which the nature of the reaction is determined quantitatively by means of a change in color. The reaction products are illuminated by radiant energy of a known wavelength and the reaction is detected and/or monitored by the reflection of the radiant energy from the sample where the reaction is occurring. A plurality of samples carried on such slides is disposed in alignment in a circle or a line and a rotor or carriage carrying plural photometers or a single photometer producing plural beams at different wavelengths is moved relative to the samples, the beams being directed at the samples. Each sample is scanned at least once as the carriage moves or the rotor rotates and the reflected radiant energy is captured by photo-responsive devices and channeled to a computer where the data is processed and information acquired concerning the respective samples with regard to end points and kinetic characteristics of their reactions.
