Waters Corp. has expanded its family of CORTECS Columns with 2.7-um silica-based, solid-core particle columns for HPLC column performance. Designed for analytical scientists who need to maximize performance on their existing LC systems, the 2.7-um columns run at lower pressures while delivering high efficiencies.
Diamond Analytics’ vFLARE columns offer unique selectivity and expand the existing range of analytical capabilities in separation science using diamond-based technology, which allows for research into new areas of HPLC methods development. The columns are based on a porous nano-diamond core shell support.
Phenomenex’s Kinetex Core-Shell Biphenyl HPLC/UHPLC columns give researchers the ideal orthogonal selectivity to traditional C18 phases. This phase is suited for a broad range of complex-mixture analyses in clinical research and forensic toxicology, food and environmental testing, and pharmaceutical, bioanalytical and DMPK studies.
W. R. Grace & Co.’s ProVance pre-packed Protein A columns are a high-performance disposable chromatography solution to help meet the growing demand for downstream purification. Increasingly, biopharmaceutical companies are shifting to single-use manufacturing for greater portability, scalability and rapid deployment of biologics.
The growing legion of scientists investigating glycans as disease markers and antibody-based biopharmaceuticals (nearly 800 publications in five years) now have an effective new tool for the challenging separations of glycans and glycan isomers.
The June issue of Chromatography Techniques speaks to game-changing liquid chromatography instruments introduced at Pittcon 2014. Other articles include new CDS platforms, how CE can help in the battle for food safety and a new ion chromatography technique, as well as IC's importance in verifying drinking water.
A combination of microfluidics and electronic integration results in simpler sample analysis.
Users are turning to increasingly simple chromatography data systems to handle increasingly complex processes.
Capillary electrophoresis has emerged as a powerful tool in the fight against adulterated food and beverage.
The capabilities of ion chromatography are essential as hexavalent chromium limits plunge ever lower in the attempt to ensure safe drinking water for all.
A decades-old theory and a new super-localization microscopy method have teamed to advance the efficiency of ion chromatography in drug discovery applications.
Researchers have developed an improved chemical analysis method that is more efficient and faster in detecting counterfeit medications, which have skyrocketed in recent years. The method identifies and quantifies the various compounds present in a pharmaceutical product, in a fifth of the time it takes governmental services to do the same job.
Reseachers found unexpected traces of water in semiconducting nanocrystals. The water, as a source of small ions for the surface of colloidal lead sulfide nanoparticles, allowed the team to explain just how the surface of these important particles are passivated, meaning how they achieve an overall balance of positive and negative ions.
In all organisms, reduction-oxidation — or "redox" — regulation is essential for many biological processes. Key to understanding these processes is being able to determine how the post-translational modifications (PTMs) of proteins, which occur in this case on their cysteine residues, contribute to creating "redox switches" capable of regulating protein functions.
Melanin— and specifically, the form called eumelanin— is the primary pigment that gives humans the coloring of their skin, hair and eyes. It protects the body from the hazards of ultraviolet and other radiation that can damage cells and lead to skin cancer, but the exact reason why the compound is so effective at blocking such a broad spectrum of sunlight has remained, until now, something of a mystery.
New analysis of ancient Jian wares reveals the distinctive pottery contains an unexpected and highly unusual form of iron oxide. This rare compound was only recently discovered and characterized by scientists and, so far, has been extremely difficult to create with modern techniques.
A professor is using a technique to study tiny fragments of glass present in the primer in bullet cartridges in great detail. This could identify glass both in gunshot wounds and on the person who has fired the gun.
A promising material is lining itself up as a candidate for a quantum memory. A team is the first to succeed in performing high-resolution spectroscopy and microscopy on individual rare earth ions in a crystal.
As smartphones get smarter and computers compute faster, researchers actively search for ways to speed up the processing of information. Now, scientists have made a step forward in developing a new class of materials that could be used in future technologies.
A chemistry professor led an effort to find a more accurate way to measure water content in pharmaceuticals– a major quality issue for drug manufacturers. He says the new technique could be 100 times more sensitive than one of the most popular current methods.
