the sample support consists of reference substances which can easily be scanned for such position calibration the white sample spots 9 are reference substances which allow an overall quality control the black sample spots 8 are the unknown analysis samples the sample supports according to this invention conform precisely in their size to the microtiter plates they can then be introduced and processed in commercially available processing stations for microtiter plates these stations have become established in biochemistry for parallel processing of many samples they are commercially available the body size of these plates is 80 by 125 millimeters with a usable surface of 72 by 108 millimeters on which today usually 384 reaction wells vials are solidly recessed into the plastic in a 4 5 mm grid if microtiter plates with 864 reaction wells in a 3 mm grid are introduced in the future these may also be used since they are the same size then the multipipette units and sample spot array for the sample blocks must be changed loading will then be faster since 864 samples each can be transferred at the same time if 96 tip multipipettes are used these can readily handle 864 well microtiter plates if only the shaft diameter is smaller than the well diameter nine sample transfer processes are then needed for each of the microtiter plates the invention is based upon the already introduced parallel processing of large numbers of samples in biochemistry and molecular genetics.
