Photometry is the measurement of light absorbed in the ultraviolet (UV) to visible (VIS) to infra-red (IR) range. This measurement is used to determine the amount of an analyte in a solution or liquid. Photometers utilize a specific light source and detectors that convert light passed through a sample solution into a proportional electric signal.

WebFor example, photometric measurement is useful for testing with a 96 or 384 multi-probe head since all transfers can be performed and measured at the same time. Each well in a 96- or 384-well plate corresponds to a channel on the multi-probe head. Since an absorbance value is collected per well, the transfer volume can be determined per channel. http://iarc.uncg.edu/elight/learn/design/lc_sub/photodis.html
