Solid phase extraction is a sample pretreatment developed from chromatography for extraction, separation, and concentration. It is mainly used for sample pretreatment of target compounds in various food, agricultural and livestock products, environmental samples, and biological samples. Solid phase extraction technology has been widely used in many national standards (GB/T) and industry analysis standards.

Thin layer chromatography (TLC) is a fast and convenient analytical technique for the separation, qualitative and quantitative analysis of substances. It is suitable for rapid identification testing in drug synthesis, monitoring and amplification of Flash and preparative chromatography, and quantitative analysis. High cost-effectiveness, capable of separating multiple samples simultaneously, and can safely and accurately identify compounds through various detection methods such as visualization and mass spectrometry (MS).

A liquid chromatography column is composed of a column tube, a pressure cap, a sieve plate, a column head, and packing. The packing, as the "heart" of the chromatography column, is the most important component. Bangkai has more than ten years of experience in producing silica gel packing, covering all processes from analysis to semi preparation and preparation. We can provide customized production of chromatography columns according to customer specific requirements.

Flash fast separation column product, with a column capacity of up to 10kg and a maximum sample loading capacity of 1000g, suitable for a wide range of solvents, and has the same excellent reliability and reproducibility as products in the same series.

As a widely used inorganic material, silicon dioxide is also a very useful pharmaceutical excipient in the pharmaceutical field. The excipient silica structure formula mSiO2·nH2O is a white powder with good fluidity, high purity and no pollution. It has the characteristics of small particle size, large specific surface area and many pores. At the same time, the silicon hydroxyl group distributed on the surface makes it have good adsorption performance. The addition of pharmaceutical excipients silica can effectively improve the quality and performance of pharmaceutical preparations, especially tablets, and greatly improve the market competitiveness of drugs.

In the food industry, silica can fundamentally solve the agglomeration caused by moisture absorption and compression in products, and has adsorption effect, making it an excellent flow promoter. It is mainly used to prevent the aggregation and clumping of powdered food, to maintain free flow, or to adsorb liquid spices, oils, vitamins, etc., making them into powder, such as powdered oils, solid spices, solid wine, etc.

There are two types of beer silica gel, one is hydrogel silica gel, the other is dry gel silica gel. While maintaining high water content, Bangkai silica gel ensures adsorption effect, activity, less bacterial colonies, higher cleaness. and solid waste, water consumption and operating expenses are reduced, so that each liter of beer needs less chemicals.
