Evaluation of the Olli C + D biochemical analyser after over a year of use in enzymology

with carry-over or drift. Automation of these RIA assays has halved the man-hours normally required and eliminated the many errors which can occur in the manual analysis and clerical reporting of large batches of specimens. One of the drawbacks of the system is that complete shutdown occurs when there is a printer failure. This failsafe system is not essential when the analyser is connected to a laboratory computer. Another feature that could be improved is the sampler. A 40 specimen sampler is too small when large batches are being proceesed. Fewer plate changes would be required if the sampler size was increased to hold 60 or preferably 100 samples.
