This application note describes simultaneous identification and quantification of more than 900 lipid molecules from a sample of human serum using a prototype small particle column and a quadrupole Orbitrap MS platform.

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

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.

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.
