    A Study of DryDisk® Background Contamination

    The DryDisk® Separation Membrane was designed to replace conventional sodium sulfate in the drying of sample extracts. The DryDisk® is a hydrophobic membrane, consisting of a GORETEX ® process filtration media based on polytetrafluroethylene (PTFE). The hydrophobic property of the membrane allows the extracting solvent to pass through it, while retaining any water in the sample extract on the membrane's surface.
