Does anyone know where one can purchase 500 mg bed SAX SPE columns with the high-capacity triethylammonium bonded divinylbenzene base?
I have been working with some B&J P/N 9084 columns that have since been discontinued and I need a replacement. Silica-based columns have not been effective.
The application is removal of carboxylic acids from the solution - the tighter they bind the better! I must able to recover the analyte (hydrazine) from the column.
Thanks
