The NexLeaf CBX for Potency is a superficially porous particle (SPP) C18 column designed for HPLC analysis of cannabinoids in various cannabis and hemp matrices. The smaller dimensions are ideal for use with any of our LCMS-8030/8040/8045/8050/8060 detectors. Guard column 220-91525-72 and holder 220-91525-73 are recommended to protect the analytical column from matrix components and prolong its lifetime.
