Viscotek has expanded its online bibliography of application notes and application chromatograms featuring the company's high performance GPC/SEC, Dynamic Light Scattering (DLS), Flow Injection Polymer Analysis and Dilute Solution Viscometry systems.

Visitors to the comprehensive online facility (available at the Article Webpage) are now able to browse through over 100 application notes and chromatograms. Regularly updated with new data, the Viscotek applications bibliography offers strong justification for book-marking and periodic revisits.

Founded in 1985, Viscotek is the global leader in GPC / SEC detectors, software and systems for the characterisation of polymers, proteins and nanoparticles. Launched in 2005 Viscotek's innovative DLS instrument range has been widely acclaimed by laboratories around the world particularly those specialising in biomolecular discovery, development and delivery, protein-protein interactions, protein conformation analysis and measurement of the stability and size of lipids and conjugates. Viscotek's innovative products and technologies are backed throughout Europe, North America and Asia by superior technical service and analytical support from experienced experts.

For further information or to discuss your polymer, protein, peptide or nanoparticulate material characterisation application please contact Viscotek.

Malvern Instruments acquired Viscotek in January 2008.

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.

SEC is further subdivided into gel filtration chromatography (GFC) and gel permeation chromatography (GPC) when an aqueous or organic mobile phase is used respectively. HPLC-based SEC systems and columns are available for analytical separation alongside SEC spin columns or filters to prep samples for many protocols.

Types of viscometer include rotational, vibrational and falling piston viscometers. Options for viscometers include modular, portable, benchtop and temperature compensation and density measurement features.Particle CharacterizationParticle characterization instruments are used to determine particle size distribution, shape, surface area, zeta potential, density and porosity of particles and materials. Multiple tecchniques are available for determining particle size, shape and count including dynamic light scattering (DLS), laser diffraction, electrozone (Coulter technique), imaging particle analysis and single particle optical sensing. Determine the density of your material with a gas pycnometer or examine its surface area and porosity with gas adsorption analyzers and mercury porosimeters.
