Standard SPE Procedure for CHROMABOND® PS-OH- (strong anion exchanger on PS/DVB)

Method:	Matrix	Application-No.:
SPE	-	304035

Substances:
Column:		CHROMABOND® PS-OH-, 3 ml, 200 mg
Phase:		CHROMABOND PS-OH-
MN catalog number:		730396
Sample pretreatment:		Sample is adjusted to pH 7-11 in relation to the anionic compounds
Conditions:		Column conditioning: 3 ml methanol, then 3 ml water. (Do not let run the column dry.) Sample aspiration: The prepared sample is passed through the column by vacuum or pressure (max. 1000 ml sample volume) Washing 1: With 3 ml 5% NH3 in water acidic impurities are removed. Washing 2 (Elution 1): With 3 ml methanol / water (20:80, v/v) neutral and basic compounds can be removed (eluated). Elution 2: Compounds are eluted with 2 x 2 ml methanol/acetone (1:1, v/v) + 5% AcOH or with 2 x 2 ml methanol/acetone (1:1, v/v) + 20% NH3

Legend:		All solvent volumes are based on the amount of adsorbent (200 or 500 mg) and have to be adjusted according to the size of used cartridge. This protocol is a suggestion for standard procedures and should be optimized (solvents, volumes, adsorbent amount, ....) due to necessity of the investigated sample or compound and subsequent analysis (GC, HPLC, ...).
