Product news

Dionex Corporation is pleased to introduce a new reversed-phase HPLC column, the Acclaim® C30. This column is suited to a broad range of separations including hydrophobic, long chain, structural isomers for example, carotenoids, steroids, and pharmaceuticals), lipids (for example, phospholipids, omega fatty acids, and cooking oils), and hydrophilic analytes (for example, water-soluble vitamins, and organic acids). The Acclaim C30 column provides unique selectivity and complements the range of other high-resolution reversed-phase Acclaim columns.

The Acclaim C30 column is based on covalent modification of high-purity, spherical, porous silica particles with a C30 alkyl chain, and provides the following benefits:

• High shape selectivity
• Unique selectivity complementary to other reversed-phase columns
• Compatibility with highly aqueous mobile phase
• High-quality columns – low column bleed, high efficiency, and rugged packing

The Acclaim C30 columns are available in 3 μm and 5 μm particle size, 2.1, 3.0, and 4.6 mm i.d. in various lengths and are ideally suited for use on the UltiMate® 3000 UHPLC+ systems.

Thermo Scientific™ Acclaim™ C30 Reversed-Phase LC Columns

Thermo Fisher Scientific

The Acclaim™ C30 is designed to provide high shape selectivity for separation of hydrophobic structurally related isomers and unique selectivity complementary to other reversed-phase columns. Acclaim C30 columns are available in 3 and 5μm particle sizes and 4.6, 3.0, and 2.1 mm diameters, with an average pore diameter of 200 Å. It is based on covalent modification of C30 alkyl silane on high-purity, spherical, porous silica gel. The combination of advanced surface modification technology and careful matching of C30 alkyl chain with the pore size of the silica substrate results in a unique chemistry ideal for separating hydrophobic structurally related isomers.The Acclaim C30 is a reversed-phase HPLC column and can be used in a wide range of applications including foods and beverages, chemical, environmental, pharmaceutical, academia, etc.The Acclaim C30 columns exhibit high shape selectivity suited to separation of hydrophobic, long chain, structurally related isomers (e.g. carotenoids, steroids, etc). They are also fully compatible with various aqueous buffers, useful for a broad application range of analytes(e.g. water-soluble vitamins, organic acids, etc) and more flexibility in method development.The Acclaim C30 column is a viable alternative to normal-phase columns for lipid analysis. The Acclaim C30 columns can be used for LC/MS applications.Acclaim C30 Reversed-Phase LC Columns Features: High shape selectivity Unique selectivity complementary to other reversed-phase columns Compatibility with highly aqueous mobile phases High-quality columns with low column bleed, high efficiency, and rugged packing Column Details: Chemistry: alkyl C30 Particle Size: 3, 5 µm Pore Size: 200 Å Surface Area: 200 m2/g Length: 50, 100, 150, 250 mm ID: 2.1, 3.0, 4.6 mm

AutosamplersAutosamplers are automated sample loaders used with a number of separation and analytical techniques. HPLC autosamplers use automated partial or full-loop injection systems and place samples in vials or microplates for analysis. Autosamplers can also be used for elemental analysis. Features to consider include repeatability, syringe capacity, footprint and temperature controls.  UHPLC and HPLCHigh performance liquid chromatography (HPLC) and ultra high performance liquid chromatography (UHPLC), also known as UPLC, are analytical techniques used to separate, identify and quantitate components of complex mixtures including biological samples such as proteins and lipids as well as chemical mixtures of pesticides, drugs and oils. Both techniques are liquid chromatographic methods but differ by operating pressures (HPLC < 6000 psi < UHPLC ). Components of HPLC and UHPLC systems include columns, detectors, pumps, autosamplers and column heaters. Explore a range of UHPLC and HPLC columns for your specific sample needs including reverse phase, normal phase, ion exchange, HILIC, ion exclusion and size exclusion columns. For more specialized HPLC, explore FPLC, countercurrent LC and simulated moving bed systems. Find the best UHPLC and HPLC equipment in our peer reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Sample PreparationSample preparation can improve the quality and speed of separation techniques. Products to assist sample preparation include filtration equipment, evaporators, membranes and sieves.LC-MSLC-MS (liquid chromatography-mass spectrometry) systems and equipment are used for separation and quantitative analysis of complex mixtures, combining liquid chromatography and mass spectrometry. Quantify proteins, contaminants, pesticides or screen for drug metabolites with a high level of sensitivity. LC-MS systems and equipment include reverse phase, normal phase and specialized columns integrated with various MS detectors such as time-of-flight (TOF), quadrupole, orbitrap or ion trap mass analyzers. LC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzer give greater sensitivity and resolving power to your analysis. Find the best LC-MS equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Preparative ChromatographyPreparative chromatography equipment is used for purification purposes, separating and collecting compounds eluted from a mixture which can then be subsequently used for further purposes. This can be done in large quantities or small. Preparative chromatography systems are usually low to medium pressure liquid chromatographs that are semi-automated. Explore a range of preparative columns and fraction collectors. Find the best preparative chromatography equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.NanoLCNano LC is a nano scale liquid chromatography technique typically used for proteomic applications. The nano refers to the very low flow rate of the mobile phase in the system. The advantage of nanoLC is its high sensitivity. Often the system is integrated with a mass spectrometer in nano LC-MS or nano LC-MS/MS. When using nanoLC equipment consider column choice, software and accurate and precise flow rate control.Medicinal ChemistryMedicinal chemistry is a broad discipline encompassing the design, identification, synthesis and development of chemicals in drug discovery. It includes a number of techniques covering structural biology, synthetic chemistry and molecular biology. Technologies used in medicinal chemistry include ADME, lab-on-a-chip, high content screening and assay assembly.
