Diol HPLC Column And C30 HPLC Column
Hawach HPLC column has become one of the most important laboratory tools for separation and purification technology, whose main function is to separate each substance in the sample. HPLC technology has been widely used in the fields of chemistry, medicine, food safety, etc. Generally, there are mainly three types of HPLC columns satisfying customers’ various requirements.
By employing the high-purity silica gel as the matrix, the Diol HPLC column uses unique bonding technology to make itself more stable and durable in aqueous media. The detailed information of the column would be described as follows.
Lutein and vitamin E are common nutrient enhancers in foods. The analytical methods for these two types of substances are clearly defined in the food nutrition enhancer use standards. The separation of isomers is also specifically illustrated. The C30 HPLC column is a specially designed column for the separation of carotenoid isomers.
First of all, the Diol HPLC column has higher selectivity than the normal-phase separated silica gel, since the hydrophilicity of the diol group is weaker than the one of pure silica gel. The polarity of its stationary phase is slightly less than the unbonded silica gel, which provides moderate positive phase retention and excellent selectivity. Besides, its high-performance silica gel and special bonding technology could stabilize the diol bonded phase in the aqueous medium without loss of column service life. Also, it has high inertness and durability.
