AquaSep is the clear choice for the discriminating HPLC chromatographer faced with a difficult separation challenge such as polar compounds, compounds requiring a highly aqueous mobile phase or difficult to retain compounds. The AquaSep phase has been specially developed using patented technology for use with highly aqueous mobile phases, including 100% aqueous. Our unique patented approach provides a complete solution to ensure that AquaSep is totally resistant to “phase collapse” under all mobile phase conditions.
The Aviator line has identical selectivity to ACE HPLC columns. Aviator AQ is a C18 bonded phase with integral polar functionality which is resistant to phase collapse even with 100% aqueous mobile phase. Recommended for applications where 100% aqueous mobile phases are required. Ideal for fast gradients due to rapid re-equilibration properties.
With an excellent reputation for performance, reproducibility and lifetime, Aviator C18 provides a rugged, reproducible starting point for method development and applications with analytes differing in hydrophobicity, polar, moderately polar and non-polar analytes, uncharged acids and bases, ionized acids or bases using ion-pairing and is an ideal starting point for method development
Aviator C18 HL
Aviator C18 HL (High Load) is a high surface area, high carbon load phase, leading to increased retention and loading compared to Aviator C18. Availability of particle sizes up to 20 microns ensures easy scale-up for preparative and process scale applications.
Aviator C4 is the ideal choice for separating polar, moderately polar, and non-polar analytes (including uncharged acids and bases, strong acids or bases in un-ionized form or in ionized form using an ion-pair modifier.) Aviator C4 columns produce better peak shape and column efficiency when separating troublesome compounds.
Aviator Cyano is suitable for use in both normal and reversed-phase modes. Provides strong dipole-dipole interaction with analytes and weak hydrophobic interaction with greatly improved performance, stability and reproducibility compared to conventional CN phases.
Aviator Phenyl exhibits hydrophobicity between C4 and C8 phases, with increased polar selectivity. Improved performance, stability and reproducibility compared to conventional phenyl phases. Compatible with highly aqueous mobile phases.
Chromegabond Amine Columns based on aminopropyl bonding provide superior, reproducible separations and long column life with excellent peak symmetry. Can be used as a weak anion exchange material or a polar stationary phase in normal phase chromatography.
Chromegabond C22 is a highly retentive stationary phase in which hydrocarbon C22 groups are bonded to an ultra-high purity support. The C22 is monomerical bound and is nonendcapped allowing this stationary to be used under wide variety of mobile phase compositions. This phase exhibits even greater hydrophobic interaction than the Chromegabond HC column. The Chromegabond C22 is ideally suited for the separation of triglycerides, PAHs, and steroids.
Chromegabond Carbohydrate is specifically design for the separation and chromatographic analysis of sugars, sugar alcohols and oligosaccharides. It is based on bonded amine groups and is used with mobile phases typically composed from 50 – 95 % acetonitrile and 50 – 5 % water. This combination provides for excellent separation and high column durability. It is available as a 250mm x 4.6mmID column packed with 5 micron particles.
Chromegabond Cyano Columns based on cyanopropyl bonding to provide superior, reproducible separations and long column life with excellent peak symmetry. Can be used to separate polar compounds in both reverse phase and normal phase chromatography.
Chromegabond DNAP II
DNAP II columns are designed specifically to handle complex petroleum samples and separatate based on aromatic ring class even for alky substituted aromatics which are normally more difficult to separate.
Chromegabond HC C18
Chromegabond HC C18 is a non end capped C18 stationary phase with 22% monomerically bonded carbon. The dense high carbon coverage forms a hydrophobic shield and prevent underlying silica support interactions with solutes.
Chromegabond LS HS
Chromegabond LS HS (Lipophilic Separations High Surface area) has been developed for analysis of lipophilic analytes such as fat-soluble vitamins, fatty acids, aliphatic pharmaceutical, and surfactants. The development of this new stationary phase evolved from our experience with fluorine based stationary phases and high surface area silicas. Many lipophilic compounds such as fat-soluble vitamins can be analyzed using reversed phase conditions on fluoro-phases.
Chromegabond PSC C8/C18
Chromegabond PSC (pharmaceutical separation column) is prepared by using a mixture of C8 and C18 groups. In addition to this unique bonding arrangement, PSC columns incorporate technology that we have developed which enables us to tightly control the level of residual silanol groups. We utilize this technology to produce PSC columns with a tightly controlled number of residual silanol groups. These columns are able to retain both highly polar and hydrophobic compounds.
