Thermo Fisher Scientific Debuts New Chromatography Consumables at Pittcon 2013
18 Mar 2013
Thermo Fisher Scientific Inc., the world leader in serving science, today announced that it will feature a number of new chromatography consumables within booth 1835 during Pittcon 2013, being held in Philadelphia from March 17-21, 2013. Among them are several columns designed for improved analysis of chemical compounds.
The company has added five phases to its family of Thermo Scientific Accucore solid core HPLC columns:
• Accucore Polar Premium, a rugged amide-embedded C18 phase offering complementary selectivity to conventional C18 columns
• Accucore Phenyl-X, featuring a proprietary reversed-phase shape selectivity with high aromatic selectivity
• Accucore C30, designed for high shape selectivity for hydrophobic, long chain, structurally related isomers
• Accucore Urea-HILIC for HILIC, designed for selectivity and low ion exchange activity
• Accucore 150-Amide-HILIC, designed to separate hydrophilic biomolecules in HILIC mode, intended for glycan separations.
Also new to the portfolio are Thermo Scientific Acclaim SEC-300 and SEC-1000 size exclusion HPLC columns designed for high-resolution separation of water soluble polymers and oligomers. They are optimized for determining molecular weight distribution and characterization of water soluble polymers used in a wide range of products found in pharmaceuticals, cosmetics, food and industrial processes. The columns are intended for research use only.
For high-resolution and high-throughput trace LC-MS analysis of the herbicides diquat and paraquat in plants, Thermo Fisher Scientific features the Acclaim Trinity Q1 HPLC column. Tests have demonstrated that the new column delivers the retention, resolution, peak shape and speed needed to improve diquat and paraquat analysis in common terrestrial and aquatic plant matrixes, without the need for pairing reagents or exotic mobile phases.
Also launching at Pittcon is the Thermo Scientific National SureStop vial, designed to eliminate variations in sealing inherent in manual tightening, while optimizing septum compression each time. The threads contain a “stop” designed to prevent under- and over-tightening. Evaporation studies have shown that the SureStop vial produces the lowest loss to evaporation and the lowest standard deviation in evaporation of any mainstream 2 mL vial. This can protect data quality by reducing a source of experimental variation.

Thermo Scientific™ Acclaim™ 300 C18 Protein and Peptide Column
Thermo Fisher ScientificHigh-Resolution Separation of Proteins and Peptides The Acclaim® 300 features 3 µm silica particles for rapid analysis of complex protein digests. The Acclaim 300’s stable bonding make these columns compatible with a wide variety of applications, including LC/MS methods.Manufacture of these columns starts with ultrapure silica that contains minimal concentrations of metal contaminants, minimizing the tailing effects of residual, exposed silanol groups. Exhaustive bonding and end-capping techniques result in stable bonding and columns that exhibit predictable reversed-phase separations with minimal secondary interactions.Acclaim® 300 C18 Protein and Peptide Column Features: Designed for high-resolution peptide mapping and protein separations High-efficiency 3 µm spherical silica substrate High-performance bonding chemistry on 300 Å pore silica Application tested for suitablility in peptide mapping Reproducible for dependable results LC/MS compatible Column Details: Chemistry: C18 Particle Size: 3, 5 µm Pore Size: 100, 300 Å Length: 2.1, 3.0, 4.6 mm ID: 10, 50, 150 mm
Thermo Scientific™ Acclaim™ Trinity P1 LC Column
Thermo Fisher ScientificAcclaim™ Trinity P1 is a unique, high-efficiency, silica-based column designed for pharmaceutical applications such as simultaneous separation of pharmaceutical drug substances and their counterions. his new column, based on nanopolymer silica hybrid (NSH) technology, provides multiple retention mechanisms including reversed-phase, anion-exchange, and cation-exchange. As a result, its selectivity can be easily optimized by adjusting mobile phase buffer concentration, pH, and solvent content concurrently or independently.The NSH technology ensures distinctive spatial separation of the anion-exchange and cation-exchange regions, which results in maximum flexibility in method development. The easy-to-optimize selectivity can be used to accelerate chromatographic separations and increase productivity.Acclaim Trinity P1 LC Column Features: Multiple retention mechanisms including reversed-phase, anion-exchange, and cation-exchange Adjustable selectivity by mobile phase ionic strength, electrolyte type, pH and organic solvent Ideal selectivity for simultaneous separation of basic, neutral, and acidic analytes Separation of hydrophilic ionic and ionizable analytes without ion-pairing reagents Applications: Active Pharmaceutical Ingredients (API) and counterions (cations or anions). Screening of pharmaceutical counterions. Both UV and an ELS detector, in series, are required for simultaneous determination of both drug substances and counterions. Mixture of acidic and basic drug substances and respective counterions. Drug substances: of acidic, basic and neutral mixtures. High throughput analysis following optimization of the selectivity and resolution. The flow rate can then be increased, and the analysis time shortened.
