title: Reduction of sample size on the Technicon SMA 6/60 continuous-flow analyzer.
abstract: The manifold of the Sequential Multiple Analyzer SMA 6/60 (4 + 2) has been modified to decrease serum sample size to 90 mul, by using a common diluent for all six channels and recycling the discard of each dialyzer into the next one. The modification can be made in less than 4 h without the need for any additional parts; the modified manifold requires one-third fewer pump lines and fewer reagents, thus reducing operating costs and simplifying instrument maintenance, while retaining the same precision, speed, low carryover, and linearity of the production model.
