This means that caution should be taken when interpreting iTLC results obtained with larger needles.The determination of free pertechnetate in partially reduced eluate as a function of volume spotted for iTLC showed a trend towards an apparent decline of the free pertechnetate fraction with increased sample volume: from 1.57 ± 0.20% when spotted with 2 μL and up to 0.23 ± 0.03% when spotted with 20 μL.
