Gradient Chromatography Grade
In addition to very high transparency in the ultraviolet-visible range, Gradient liquid chromatography solvents must contain very small amounts of water, acid, alkali, and solid residue after evaporation. To achieve such accurate specifications, high quality raw materials and advanced distillation equipment are used to produce gradient liquid chromatography solvents and make them available to users. Passing through a 0.2 micron filter is an essential process in the production of chromatographic solvents that takes place just before the packing process. These solvents are suitable for a variety of liquid chromatography techniques.
Isocratic Chromatography grade
The solvents in this category have the purity of gradients. Because the sensitivities of the isocratic chromatography method are less than those of the gradient type, special solvents of isocratic chromatography are provided in such a way that in addition to low operating costs, they provide high-resolution separation.
