Abstract A code system for the identification of a sample group to be measured in a multi-channel photometer or in any other multi-channel analysis equipment, e.g. in a spectrophotometer, fluorometer, luminometer, turbidometer, nefelometer, cell counter, or isotope counter. The samples to be measured have been fitted in the matrix form into cuvette sets, sets of test tubes, or pit plates, and the measurement takes place preferably in the vertical direction. The sample group to be measured is provided with a related code piece, such as a code plate, containing the measurement points to be ready by means of the analysis equipment. According to the invention, the measurement points of the code piece are in the same order and with the same relative distances as compared with the measurement channels of the said multi-channel photometer or any other multi-channel analysis equipment, or with a part of or a multiple of said channels. The code piece is arranged so as to be readable by means of the measurement channels of the multi-channel photometer or any other multi-channel analysis equipment in one or several subsequent steps without using a separate code reader.
A coding system for multiple channel optical analysis equipment comprising: a sample holder including a plurality of specimen wells into which the specimens to be analyzed are disposed, said specimens wells being arranged in a matrix; and a code piece mounted on said sample holder for indicating the measurement points to be read by said optical analysis equipment, said code piece including optical indicia means for reading by said optical analysis equipment, said indicia means being arranged in the same order and with the same relative distances as at least one row of said matrix of said specimen wells and said measurement channels of said optical analysis equipment.
