Evaluasi Lempeng HPTLC Daur Ulang untuk Analisis Kualitatif dan Kuantitatif
ABSTRACT: The eficiency
chromatography of HPTLC plate is better than conventional TLC plate but it more
expensive. Due to the higher price of HPTLC plate compare to conventional TLC
plate, the application of ";re-used"; HPTLC plate has been tested.
After being used for analyzing samples, the plates were developed again with
the mobile phase, then dried for 60 min before using for the next measurement.
The qualitative chromatography profile showed that ";re-used"; HPTLC
plate has less contaminant than new HPTLC plate and the RSD of the precision
quantitative testing of the plates reused
three times showed a value > 2%.
