Special Nano Silica Layer for PAH Analysis

This is silica gel impregnated with caffeine for the analysis of polycyclic aromatic hydrocarbons. This plate is ready to use for the method recommended in the German standard DIN 38407, part 7, because the layer already contains the required electron acceptor.

The Nano-SIL-PAH HPTLC plate is coated with our well-known nano-silica with 60 Å pore size and 2 – 10 µm particle size. Due to the outstanding separation performance of Nano-SIL-PAH, the six PAHs can be very well quantitated.
