Overview
YMC Company produces a wide variety of fillers with complete specifications, especially reverse phase fillers, making it one of the few manufacturers in the world that can simultaneously provide such a rich variety of fillers. There are two types of fillers: spherical and irregular, each with a wide variety of varieties. Spherical fillers can be used for analysis and preparation of chromatographic columns. Compared to irregular fillers, due to its high uniformity, it has higher column efficiency, better loading reproducibility, and low pressure drop. Irregular packing is commonly used in the preparation of chromatography columns and open chromatography columns.
Product Details
For all fillersYMCThe company has implemented thorough quality management and achieved inter batch(Lot-to-Lot)Reproducibility. It has been adopted by many customers in the fields of medicine, chemistry, food, etc. both domestically and internationally.

YMC*GELCharacteristics of chromatographic packing materials: ☆ Already registered in the United StatesFDAThe drug master file（DMF）In addition, it has obtained safety certification for fillers; ☆ The particle diameter is10um、15um、20um、50um、75um、150umof6Planting and implementing strict quality management; ☆ For large-scale preparation (column diameter size)50mmAbove), the particle diameter distribution is narrow and the performance is high. The particle diameter is20um、50um、75um、150umThe filling material is the most effective; ☆ YMCThe preparation of spherical fillers includes reverse phase, normal phase, optical isomer separation, etc., and the types of functional groups are very rich. Selection criteria for chromatographic packing materials:
