Improved design with a dual wall housing (Glass and Plastic). Glass prevents diffusion, ensuring a leak and contaminant free system (Glass and Plastic).
1 mL Methanol
1 mL DI Water
Pretreated sample, pH 6-7
1 mL 25 mM Ammonium Acetate Buffer, pH 6-7
1 mL Methanol, dry under vacuum for 2-5 min
1 mL 5% Formic Acid in Methanol
Based on 100 mg/1 mL sorbent mass. The above is a convenient starting point for SPE
method development, further optimization may be required to tailor the method for your
specific extraction needs.
