Preparation of gel-type liquid chromatography packing and method for detecting sodium gluconate, saccharide and white sugar in water reducing agent compound liquid by using the same |
| abstract |
The invention discloses a preparation method of a gel-type liquid chromatography filler and a method for detecting sodium gluconate, saccharide and white sugar in a water-reducing agent compound liquid by using the same. In the present invention, methyl acrylate, acrylamide and 1,10-undecanadiene are copolymerized on the surface of a solid material to obtain a silica microsphere chromatography filler with moderate hydrophilic-hydrophobic surface modification. Acrylamide and methyl acrylate in the chromatography packing have moderate polarity and 1,10-undecanadiene has a significant non-polar character, making the hydrogel-coated silica packing effective for saccharide analytes. They all have good separation selectivity, and can quickly and accurately obtain the content results of sodium gluconate, saccharide and white sugar in the superplasticizer compound solution at the concrete construction site, providing reliable and efficient evaluation and analysis of the concentration of superplasticizer on site. method of analysis. |
