Brandwise Description of HPLC Products

Monitor columns are an excellent alternative for most C18 applications requiring base-deactivated columns, especially for difficult pharmaceutical and peptide applications.
C18, C8
Surface Area: 450; Pore Size: 100 Å; Pore Volume: 1.1; pH Range: 2 – 8; Particle Sizes: 3 µm, 5 µm

Reliasil was designed specifically to yield columns with a high efficiency and Guaranteed to be a perfect column equivalent to Waters Spherisorb® and a very close match to Hypersil. A proprietary type A silica manufacturing process is employed which yields a Gaussian particle distribution, narrow pore-size distribution, and strong resistance to high pH. The result is a material that is perfect for packing high-efficiency columns for general utility. Reliasil is an oligomerically derivatized silica gel. It is preferred by many chromatographers for its chemical stability and effectiveness in the reversed phase separations of peptides, pharmaceuticals, and derivatized amino acids.

Surface Area: 190; Pore Size 90 Å; Pore Volume: .5; pH Range: 2 - 9.5; Particle Sizes: 3 µm, 5 µm, 10 µm

Emerald is based on Reliasil this material is a direct equivalent for Hypersil BDS

Prestige a State of the art Base-Deactivated Silica. Double end-capping and narrow particle size range contribute to superior base-deactivation and low backpressure. Prestige is an equivalent for Hypersil Hypurity
Surface Area: 190; Pore Size 90 Å; Pore Volume: .5; pH Range: 2 - 9.5; Particle Sizes: 3 µm, 5 µm, 10 µm

Matrix brand is an excellent, low-cost choice of analytical columns for routine analysis. Based on ultra high purity silica
C18 densely bonded to produce an inert material ideally suited for the analysis of basic compounds. The resulting hydrophobic surface is also stable over a wide pH range (2-9) to allow for excellent method flexibility.
C18AQ features the traditional C18 ligand interspersed with hydrophillic end-capping groups. The resulting material is easily ‘wettable’, and unlike conventional C18
materials, does not exhibit retention loss in high aqueous conditions. Equivalent to YMC AQ,

Jordi
Jordi offers the broadest range of polymer-based surface chemistries on the market addressing aqueous, organic, and ion exchange sample preparation. Jordi resins are made from 100% divinylbenzene making them more retentive than standard PS-DVB packings. This makes J-Clean SPE one of the most retentive phases available, providing increased analyte recoveries.

• Outstanding recovery due to the highly retentive nature of polymeric phases
• Absence of leachables from the polymeric media since there is no bonded phase
• Lack of residual silanol groups
• Incredible ruggedness of polymeric supports allows wide pH and solvent compatibility
• Improved batch to batch reproducibility
• Higher capacity for improved detection limits and reduced resin volumes

Epitomize CSP 1, 2
Epitomize CSP1 Chiral columns are based on cellulose tris (3,5-imethylphenylcarbamate)
coated on 5µm spherical silica with 10µm and 20µm available upon special request.
All the columns of this type should be operated under normal phase conditions. The columns are shipped in a n-Hexane / 2- propanol solvent mixture (90:10 v/v). All columns are quality tested prior to packaging. Epitomize CSP1 Chiral columns are particularly effective for the separation of steroids (alprenolol, atenolol, pindolol, etc.) beta blockers, atropines, amines and alkaloids

Chirobiotic
Macrocyclic Glycoprotein Stationary Phases for Chiral Separations and Highly Selective Achiral Separations. phases are based on covalently bonding macrocyclic glycoproteins to a high purity 5 micron silica gel in such a way as to establish it’s stability while retaining essential components for chiral recognition.
