The Origin of Cat Litter
Cats have natural instincts to bury and cover their waste in the soil in hope of hiding their presence and scent from predators in the wild.

Endcapping is most often used with reversed-phase HPLC columns. Endcapping of the HPLC Column minimizes silanol interaction by reducing residual silanol group.

Chromatography is a process for separating components of a mixture and is widely applied in fields of fine chemistry, analytical chemistry, Organic Chemistry, Biochemistry, food safety, biomedicine, plant extraction, scientific analysis, environmental monitoring, petrochemicals, and many other fields.

In thin-layer chromatography (TLC), the stationary phase is a thin layer of solid material, usually silica-based, and the mobile phase is a liquid in which the mixture of interest is dissolved. Thin-layer chromatography comes with the advantage of photographing well, making its output easy to digitize.

In applicaiton, sensible choice of right solid phase or packing material is the core of Chromatography, for it plays a significant role in the results and efficiency of extraction and purification process. Qingdao Bangkai Hi-tech Materials Co.,Ltd is specialized in the research and manufacturing of chromatography related materials and equipments with an individual R&D center.

Our glass, aluminum foil, and PET (polyester) TLC plates are available coated with a variety of matrices and are available with and without fluorescent indicators.

According to the base of TLC plates, we can offer preparative glass TLC plates, analysis glass TLC plates and aluminum analysis TLC plates.

Column chromatography silica is characterized by the difference in adsorption retention time of different components in the mixed material; To achieve the purpose of separation and purification.

Column chromatography and C18 and TLC plate are widely used in separation and purification.

Hydroxyl is a hydrophilic group, it has strong hydrophilicity, that’s why silica gel can absorb moisture.

When the particle size of silica gel is in large range, we always think that it is not uniform particle size. Sometimes, if all of them are large size, the solvent will pass quickly without resistance. But if there are small size, the solvent will pass slowly with high resistance.

TLC plates​ is a fast and economical choice before we use the flash or HPLC.
We need only a little materials, but can get large batch processing capacity, for example, we can treat 20 samples together.
For qualitative analysis, it can be used to identify whether it is the same substance; For quantitative analysis, the purity of the substance can be judged; It can also be used for micro preparation (less than 500mg).
