Separations Products & Reviews

UCT's Enviro-Clean® Polymeric WAX Cartridges w/Polyethylene frits have been successfully utilized for the extraction of 26 diverse per- and polyfluoroalkyl substances (PFASs) in drinking water in addition to the 14 covered in the US EPA Method 537.  

Derivatization is often used to visualize specific substance classes after separation on HPTLC glass plates (20 x 10 cm). Due to its unique and patented “micro droplet” spraying technology, the fully-automated HPTLC PRO Module DERIVATIZATION ensures homogeneity and reproducibility in applying derivatization reagents.
