Aug 01, 1970  A simple method for the direct determination of the K + concentration in undiluted blood serum is described. The reproducibility of single determinations using the readings after 60-sec contact of a valinomycin liquid-membrane electrode with the sample is 0.07 mequiv/1 K + (standard deviation). No corrections are needed for the presence of other ions in the sample solutions.

1. First, despite their name, many of them are not entirely ion-specific. For example, the sodium electrode you will use also responds to potassium ions, although not with the same sensitivity. This means that Na+ will be overestimated if a high concentration of K+ is present. Mathematical techniques have been devised to compensate for this. 2.
