Dyes and intermediates are non-volatile organic substances and so best suited for HPTLC analysis. HPTLC analysis is very low cost and results are “visible”.
HPTLC is a most versatile analytical technique which offers a great separation power using precise sample application, software-controlled chromatographic steps,
The Iatroscan TLC/FID chromatograph is manufactured by Mitsubishi, Japan and sold in India by Anchrom since 1978. It combines the advantages of separation by TLC (of non-volatiles) with detection by FID (popular detector in GC).
An entirely new generation of HPTLC System, specifically for Q.C. lab applications has been launched by CAMAG, Switzerland. There will be up to 5 identical looking instruments side by side with conveyerised movement of plates. Each instrument will perform one step of HPTLC procedure.
