Abstract
Abstract A liquid sample analysis arrangement comprising a liquid sample receiving, holding and transferring strip medium made from an elongated tape having a plurality of spaced liquid sample absorbing locations on one face thereof, and an analyzing strip medium comprising an elongated tape which is divided into a plurality of discrete analyzing portions; said arrangement may be used in conjunction with an analyzing apparatus comprising means for dispensing liquid sample to the receiving medium and means for causing transfer of the dispensed liquid sample to a plurality of the discrete portions of the analyzing medium, whereby a separate analysis of a single liquid sample may be performed on each of the discrete portions of the analyzing medium; an alternate embodiment of analysis arrangement has sample dispensed to the receiving medium and has a reagent on each discrete portion of the other strip medium, with the reagent from each portion of the latter medium being transferred by the analyzing apparatus to the former medium so that discrete analyses are performed on the former medium; in a still further embodiment, the sample-receiving medium is also divided into a plurality of discrete portions, so that back transfer of each reagent, as in the alternate embodiment, is only to one discrete portion of the receiving medium.
