KromasilWe have a complete set of packing systems from analytical to preparation types. Currently, we can provide packing bonding phases including C18, C4, C8, SI, NH2, CN, Phenyl, Diol, as well as chiral packing TBB and DMB. There are three types of apertures: 60A, 100A, and 300A, which meet different analysis conditions. The particle size of the filler can be provided in six types: 3.5um, 5um, 7um, 10um, 13um, and 16um. It can be said that the variety is complete and the quality is high· Kromasil has high carbon content, low surface polarity, and high separation degree due to its high column efficiency and good peak symmetry. He passivated almost all hydroxyl groups, greatly reducing the severe tailing phenomenon of alkaline substances on the silicone matrix, and making the peak shape have good symmetry· The surface of Kromasil has good chemical stability and is composed of silicon hydroxyl groups (single functional groups). It has a high coverage of silane and is not easily hydrolyzed or decomposed under high or low pH conditions. It can be used in a solvent with a pH between 1.5-9.5 as the mobile phase· Kromasil is a high-purity, spherical silica gel filler with high chemical purity. The extremely low content of metal impurities reduces the chelating effect of some chelates on the silica gel matrix· High mechanical strength and high load mechanical strength are crucial for the lifespan and operation of fillers. Kromasil can operate normally under high pressure of 6000psi (400bar), with stable column efficiency and long service life. Due to its high specific surface area, i.e. high load capacity, it is suitable for the determination of high concentration samples.
