Product Information: Neurosyil refers to a brand of HPLC (High-Performance Liquid Chromatography) columns used for separation and analysis in a laboratory setting.
Neurosyil Semi Prep/Preparative columns are used in semi-preparative liquid chromatography (LC) to purify and collect target compounds from a sample in larger quantities than analytical HPLC.
“Neurosyil” is a brand name primarily associated with HPLC (High-Performance Liquid Chromatography) columns used in laboratory and analytical settings for the separation and analysis of peptides and proteins.
Purification and isolation of substances: They are used in chemical and organic laboratories to purify and isolate various chemical compounds.
Ultimasyil Columns are packed with silica gel having very high purity at 99.99% SiO₂.
Narrow particle size distribution is the hallmark of Ultimasyil Columns technical engineering.
Particle size is steady to maintain high product reliability.
Wide pH range of 2–8 helps for long column lifetime.
Silica surface is covered by hydroxyl groups (–OH) called Silanol (Si–OH) to improve wetting in solvent or low polar systems, and various chemical treatments are applied to mask this functional group.
These treatments can also moderate hard settling, mar and burnish resistance & UV performance.
Ultimasyil Column Phases: C18, C8, Phenyl, Cyano, Amino, Silica, AQ (Hydrosphere), Diol

100Å provides adequate resolution & retention for most applications.
In general, reverse phase application will require a modifier in the
mobile phase compared to 80Å application.
Wide pH stability for long column lifetime and method flexibility.
Ultra high purity silica used.
