The December issue of Chromatography Techniques details a mass spectrometry technique enables the detection of drugs and medical conditions from just a single drop of fluid, such as blood or urine, within minutes. Other articles include: size of future mass spec, choosing HPLC columns, soft ionization, separation of antibodies. There are also new products.
Because of the high cost of HPLC columns, there are numerous ways to find out which column(s)...
Pre-formulated buffers for pH gradient have greatly simplified the development of ion exchange...
Mass spectrometry (MS) is the workhorse of analytical chemistry. It performs the analysis of the sample, making MS equipment an essential part of the analytical instrumentation market. A recent shift in the laboratory landscape, however, is forcing a change in the size and functionality of mass spec equipment.
Researchers at Purdue Univ. have pioneered a separation technique that can be used in everything from homeland security and law enforcement to drug discovery and biomedical applications. The technique, called slug flow microextraction, makes it possible to quickly detect the presence of drugs or monitor certain medical conditions using only a single drop of blood or urine.
Phenomenex has extended its SecurityGuard family of products to include a cartridge-based system that protects any non-aqueous gel permeation chromatography (GPC) column. The cartridge system replaces traditional guard columns, offering a more convenient and cost-effective system for protecting expensive GPC columns from the damaging effects of contaminants and microparticulates.
Every LC lab has a cache of C18s, but every C18 is not created equal. Because the chemistry tends to be similar, the silica support that carries this ubiquitous octadecylsilane phase becomes vitally important.
JM Science offers a complete line of Shiseido HPLC Columns. CAPCELL PAK is an epoch-making HPLC column integrating the enhanced separation performance of silica-based, polymer-coated packing material. It provides columns of reversed phase partition mode, normal phase partition mode and ion exchange mode.
EMD Millipore has added three chromatography resins to its Chromabolt prepacked columns. These pre-validated chromatography columns come packed with either strong cation exchangers, weak cation exchangers or strong anion exchangers, freeing up end users’ time and resources by eliminating manual column packing and cleaning.
Innova Biosciences has launched InnovaGOLD, a range of ultra-high-quality gold nanoparticles that have demonstrated improved sensitivity, stability and reproducibility in immunoassays compared to other commercially available gold colloids.
Shimadzu Scientific Instruments has added to its integrated liquid chromatography systems line with the Prominence-i and Nexera-i. Combining enhanced functionality, an intuitive operating environment and full automation, the series provides excellent performance and a more efficient workflow for conventional to ultra-high-speed analysis.
Wyatt Technology’s DynaPro Plate Reader II can run automated high-throughput screening-dynamic light scattering analyses to characterize protein-protein interactions in standard microwell plates, under multiple conditions in a significantly reduced time frame, making DLS a viable option for stability-indicating parameter (SIP) screening.
Restek has developed a new certified reference material (CRM) of four PAHs—benz[a]anthracene, benzo[a]pyrene, benzo[b]fluoranthene, and chrysene—designed for greater convenience, longer shelf life and increased long-term accuracy.
Practichem has added to its Chromponents line with the BioD3, a compact LED-based UV and conductivity detector, and FluidSwitch, a line of biocompatible rotary valves. Chromponents is a series of modules designed for easy configuration.
Phenomenex has added Phenova Certified Reference Materials (CRMs), a line of ISO/IEC 17025- and ISO Guide 34-compliant standards for the calibration of analytical equipment and quantitation of analytical measurements for environmental testing.
Now, OEMs can give gas chromatography users the high analysis repeatability and low detection limits they demand, thanks to the FAS 16 mm FASPROP low flow proportional valve from Norgren. With a small orifice—just 0.002” (0.05 mm)—and compact design, the valve precisely controls low flow rates in the mL range (up to 174 psi/12 bar), enabling the use of most common carriers.
New Star Environmental’s Frog-4000 is a fully contained purge and trap GC system with analytical capabilities that are comparable to a commercial lab, with the advantage of its compact size.
GOW-MAC’s programmable, microprocessor-controlled gas chromatograph, the Series 8100, features a broad, flexible platform that allows for custom, application-specific system configurations for research, industrial, laboratory, academic and QA/QC environments.
Gems Sensors & Controls’ BL Series is designed to support demanding fluid control requirements, such as those common to natural gas separation, natural gas plunger lifts, gas chromatography equipment, irrigation systems, pneumatic pipelines and others.
The Bal Seal Canted Coil Spring, a current-carrying, locking, latching and holding solution, is available in a range of coil heights and materials. Its unique design enables it to maintain a nearly constant force over a broad compression range, compensating for large mating tolerances and temperature changes without significant deviation from its initial force.
Agilent Technologies’ 5100 Inductively Coupled Plasma – Optical Emission Spectrometer (ICP/OES) allows customers to run samples faster, using less gas and without compromising performance on even the toughest samples.
VGC Chromatography’s DA columns produce faster, more-efficient separations than conventional open tubular columns.
With the advent of superficially porous particles (SPP or “core-shell” particles), the analytical community found the ability to gain far more efficiency and speed out of existing HPLC instrumentation.
Phenomenex has released its Zebron ZB-CLPesticides-1 and 2 for dual-column pesticide testing by GC/ECD (electron capture detection). This column set saves time and money for chlorinated pesticide testing commonly performed by environmental and drinking water testing labs, which often need to run up to seven EPA methods on a single instrument.
Many laboratories analyzing monoclonal antibodies (mAb) regularly encounter situations where they need alternative hydrophobic interaction chromatography (HIC) selectivity.
Agilent Technologies has added the AdvanceBio Glycan Mapping Column to its AdvanceBio family of columns. It is specifically designed to deliver fast, high-resolution glycan separations.
The September issue of Chromatography Techniques details the MS focus on biological and clinical research at the recent American Society of Mass Spectrometry conference. Other articles include: ensuring HPLC success, advancing UHPLC, effectively using hydrogren in the lab, and thin-layer chromatography for the detection of explosives. New products and columns are also included.
