Fast clean extracts High recoveries Largest range of SPE columns Custom columns service SPE Accessories
The Q-SPE range of Solid Phase Extraction Columns are available in all the chemistries in use today, as columns, discs, cartridges and 96-well plates. The bonded particles have hydrophilic characteristic, resulting in broader analyte selectivity via retention of both hydrophobic and hydrophilic moieties. The high purity 60A, 50 micron silica has the least Silanol activity compared to many other silicas, producing rapid, accurate, sensitive and reproducible results. Q-SPE Columns are available in sizes from 1mL to 60mL with sorbent weights from 50mg to 10gms. Our custom column service is available for customers requiring specific sizes of columns or weights of sorbents. We also work with clients on specific projects requiring special packings and column treatments; please contact us to discuss your requirements.
