The HPTLC is an effective tool to verify the fingerprint of plant material against a reference plate. We are able to confirm the profile of a plant thanks to this tool and ensure the right material is being used.
With an HPTLC, individual components of a mixture are separated on a thin glass-coated plate, which is then placed in a developing chamber. The TLC plate is placed under ultraviolet lamp, and bands of the different components are visualized. Unlike a standard TLC, with an HPTLC many tasks are automated via robotics, eliminating uncertainty from samples being applied to plates by hand.
We use the HPTLC to detect if products have been contaminated by mycotoxins, a dangerous class of toxin that can develop on plant matter in humid conditions.
