Zusammenfassung:Method and apparatus for photometrically testing for a constituent of a droplet of a discrete liquid sample having an arcuate surface and having a planar surface resting on or suspended from a surface and wherein light rays from a source are directed into the droplet through the planar surface thereof. Light energy as a measure of absorbance, light scattering or fluorescence is transmitted through the planar droplet surface to a photodetector for analysis of the sample which analysis may be qualitative or quantitative or indicate an end reaction. Such analysis may be automated.
