- ๐ฌThe pretreatment column SPE C18/H/Na/Ba/Ag for ion chromatography is developed based on the principle of solid phase extraction. With materials of high cleanliness and the principle of reverse phase adsorption and ion exchange, it can effectively remove impurities such as organics and impurity ions from the sample, avoiding the pollution of impurities on the ion chromatographic column and the impact on separation
- ๐ฌIt is specially used for ion chromatography detection. The method is simple and easy to operate. It can push the liquid sample or extract directly through the column with pressure to achieve purification effect
- ๐ฌC18 and RP are commonly used reversed-phase pretreatment columns, both of which can purify hydrophobic compounds in the sample matrix. However, due to its nature, C18 filler is not suitable for the case where the pH of sample matrix is too high or too low. RP is C18 with special treatment, and the applicable range of PH can reach 0-14.0
- ๐ฌH-type and Na type are mainly used to purify alkaline earth metal ions and transition metal ions in the matrix. H-type can also purify carbonate ions and neutralize the strong alkalinity of the sample matrix. Ag type is mainly used to purify Cl -, Br -, I -, AsO4-3, CrO4-2, CN -, MoO4-2, PO4-3, SeO3-2, SO3-2, SeCN -, S-2, SCN -, WO4-2 and other anions in the sample matrix. Ba type is mainly used to purify SO4-2 in ion chromatography sample matrix
- ๐ฌThe treatment column is a disposable consumable, and it is not recommended to reuse it, so as to avoid that after the first use, the column has been saturated, and there is no purification effect subsequently, which will affect the analysis results
