ISOLUTE Sodium Sulfate Drying Cartridges
The use of sodium sulfate (Na 2 SO 4 ) for drying water immiscible sample
extracts prior to analyte derivatization or analysis is well documented.
Traditionally this is achieved by adding loose material to the extract, followed
by filtering or pipetting off the dry solvent.
ISOLUTE Sodium Sulfate Drying Cartridges are designed for efficient in-line
drying of water immiscible extraction solvents. The cartridges feature a
female Luer inlet and male Luer outlet, allowing them to be attached to the
outlet of any SPE column. Elution solvents are dried as they pass through
the cartridge.
The cartridges contain 2.5 g of high purity sodium sulfate, with capacity for
up to 1.2 mL of water per gram. For additional capacity, two or more cartridges
can be joined in series.
