Chromatography Adsorbents Description
Chromatography adsorbents are regularly used in pharmaceutical & chemical industries, where primary issue of chromatography is to make final pure compounds or make a impurity profile studies for pharmaceutical & natural products. Column chromatography methods are help in extractions, separation & purification of organic products & effective drug substances. The chemical components of a mixture have almost the same physical and chemical properties and hence can’t be separated by other usual methods of separations
Sorbead India with specialized tie up with "Swambe Chemicals" manufactures & suppliers of silica gel & alumina powder for chromatographic separations, with an aim to offer various particle sizes & various pore diameters products, which is required for complex chromatographic separations.
The silica gel and alumina brockmann I-II grades which are manufactured are as gravity grade, flash grade and normal phase pore diameters. Alumina is being provide as acidic, neutral and basic grades. Silica gel column measures the pore diameter using the BET method which guarantees the best and most accurate results during manufacturing process.
We are manufacturing stationary phase chromatography adsorbents for research laboratory use:
1.Aluminium Oxide Chromatography- Aluminum oxide powder is a whitish colored powder which is used for chromatography and is highly porous and water adsorbing. With a bulk density of 800-920 gm per liter and a surface area of 180-240 square meters per gram, in this way adsorbents are suited for various applications like column chromatographic separations, food colors, dyes & spectroscopic chemicals, herbal and natural products, isolation and antibiotics purification.
2.Silica Gel Chromatography- Silica Gel Powder having different mesh sizes which are between 35-800. Silica Gel particle size distribution offers an excellent flow rates and a high level of harmony. The common surface area of these gels is 400-800 square meters per gm. Sorbead India adopts highest quality standards for such a sensitive & accurate product, which ensures batch to batch reproducible results for any chromatographic separations. Silica gel powder is used in different grade of column in chromatography technics. The grades like silica gel 35-70 mesh, silica gel 60-120 mesh, silica gel 70-230 mesh, silica gel 100-200 mesh, silica gel 230-400 mesh, silica gel 400-800 mesh which all mesh sizes are suited for silica gel column chromatography.
Elements of Chromatography:
- Stationary Phase Chromatography (Silica gel and Alumina Chromatography)
- Mobile Phase Chromatography (Solvent/Liquid Chromatography)
In stationay phase classification of column chromatography is depends upon either solid or liquids, while as in mobile phase (moving phase) chromatography is either gases or liquids. The most common stationary phase adsorbents for column chromatography are silica gel and aluminium oxide. While as mobile phase is liquid, it is either pure solvents or mixture of solvents. It needs complementary act between solvent & compound’s polarity.
Types of chromatography, we are supplies:
- Normal Phase Chromatography
- Thin layer Chromatography
Solid liquid Chromatography
- Gravity Chromatography
- Flash Chromatography
Thin Layer Chromatography
TLC (Thin Layer Chromatography) is a method for evaluating mixtures to isolate compounds from desired mixture. It is used in analytical study to evaluated microgram quantity samples and it takes 5-10 minutes for results. Thin layer chromatography having Z grades sizes using silica gel powder. The grade size like silica gel for TLC GF 254 for making glass plates, Silica Gel G for TL Chromatography, silica gel G and H for TLC, in which silica gel G offer with binder and silica gel H offer without binder process.
Size available for TLC:
- Silica gel G for TLC (with binder)
- Silica Gel H for TLC (without binder)
- Silica Gel GF 254 (with fluorescent indicator)
- Silica Gel HF 254 (with fluorescent indicator)
