Overview
Ethylenediamine-N-propyl silane silica gel is a silica gel bonded ethylenediamine-N-propyl phase containing both primary and secondary amines. He is a weak anion exchanger with pKa values of 10.1 and 10.9. In terms of selectivity, it is similar to the ammonium propyl solid-phase extraction phase (NH2), but due to the presence of secondary amines (0.98-1.05 meq/g), it has a larger capacity.
Product Details
ethylenediamine-N-Propylsilane silica gelIt is ethylene diamine bonded with silicone gel-N-propyl phase, containing both primary and secondary amines.He isWeak anion exchangers with pKa values of 10.1 and 10.9In terms of selectivity, it is compared to the solid phase extraction of aminopropyl(NH2) is similar, but due to the presence of secondary amines (0.98-1.05)meq/g）So the capacity is larger.
ethylenediamine-N-Propylsilane silica gelWhen used for the analysis of multi residue insecticides in food, its strong affinity and high capacity can be used to remove fatty acids, organic acids, some polar pigments, and sugars. At the same time, it can reduce the influence of matrix enhancement effect during the process of food gas chromatography analysisGC-FID and GC-MS test its excellent purification effect.
