| Standard SPE Procedure for CHROMABOND® SA (SCX, strong cation exchanger) | Method: | Matrix | Application-No.: | SPE |
| 304520 | | | | | Substances: | | amines; amino acids | | Column: | | CHROMABOND® SA, 3 ml, 500 mg | | Phase: | | CHROMABOND SA | | MN catalog number: | | 730108 | | | | | | Sample pretreatment: | | Sample is adjusted to pH 2-7 in relation to the cationic 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 AcOH / water (5:95, v/v) impurities are removed. Washing 2 (Elution 1): With 3 ml methanol / water (20:80, v/v) neutral and acidic compounds can be removed (eluated).
Elution 2: Compounds are eluted with 2 x 2 ml methanol/acetone (1:1, v/v) + 5% NH3 or with 2 x 2 ml methanol/acetone (1:1, v/v) + 20% AcOH
