Colored silicone gel
GRACE dyed silica gel (grade 923) is a high-purity chromatographic silica gel specifically designed for analyzing hydrocarbon content in gasoline, as specified in GB/T11132 and ASTM D1319 standards. It has a very narrow pore size distribution, with an average pore size of 32A, and is in the form of amorphous particles.
GRACE dyed silicone (grade 923) is produced by GRACE, a professional silicone manufacturer with over 150 years of history in the United States. All products are imported with original packaging. All relevant performance indicators of the product comply with the product specifications.
GRACE dyed silicone gel (grade 923) from the United States is packaged in drums or plastic bottles, with drums weighing over 2kg and plastic bottles weighing 500g.
The company also has original imports from the United Statesfluorescent indicator(Stained silicone)Precision inner diameter adsorption columnDiscounted prices!
The National Quality Supervision Administration has released the national standard GB-17930 "Unleaded Gasoline for Vehicles", which not only requires lead-free gasoline for vehicles, but also adds indicators such as aromatic hydrocarbon content and olefin content, and puts forward clear requirements. The determination of aromatic hydrocarbons and olefins content adopts the national standard GB-11132-2002 "Determination of Hydrocarbons in Liquid Petroleum Products" (Fluorescent Indicator Adsorption Method), which is equivalent to the American Society for Testing and Materials standard ASTM D1319-99. This standard specifies the use of fluorescent indicators to display the main hydrocarbons in liquid petroleum products on a silica gel adsorption column. The performance and indicators of silica gel have a significant impact on the analysis method and directly affect the separation effect of various components in the sample, determining the accuracy of the results.
