✦ Synopsis

Duplicate samples containing ~5.0 pg I:. Each pilir was included in a tliffcrcnt cxpcrimcnt, thus these results reprcscnt the precision obtained over a period of several months.

by including a pair of G pug F standards in seven different esperiments (Table II). Of many standard curves constructed over several months, no point has deviated by more than 10% from the resultant line. Although insufficient samples have been analysed to allow a meaningful statistical analysis, it is apparent that samples run in duplicate should not deviate by more than 5% from the true value. Precision appears to improve in the range IO--20 pg l?, but little work has been clone at these concentrations.
