An inexpensive system of automated flame photometry of serum sodium and potassium.

An inexpensive automated flame photometry system has been produced by utilising an I.L. 143 flame photometer fitted with an analogue output connected to a sampler (Auto Analyzer or other). The pump of the I.L. 144 dilutor is used to aspirate the sample and a variety of single or two pen recorders can be used to record the results at the rate of 60 specimens an hour.
