A new method for analyzing biological samples based on their chemical makeup is set to transform the way medical scientists examine diseased tissue.
Using an ingenious setup, scientists have calculated the force of molecular motors acting on inner components of biological cells, known as organelles.
Scientists investigating heat decay from radiogenic granite in the Darling Range have discovered that the maximum heat output has exceeded previously known data.
Scientists have pioneered a tabletop magnetic pulse generator that does the work of a room-sized machine– and more.
Researchers have discovered a molecule that is produced during exercise that contributes to the beneficial effects of exercise on metabolism.
Scientists have obtained the first detailed molecular structure of a member of the Tet family of enzymes. The finding is important for the field of epigenetics because Tet enzymes chemically modify DNA, changing signposts that tell the cell's machinery "this gene is shut off" into other signs that say "ready for a change."
The December Chromatography Techniques cover story details a method using QuEChERS combined with GCxGC TOF/MS and a clean up method to accurately detect pesticides in tobacco samples. Other articles discuss: the value of helium, evolving column technology, and a product spotlight on a new mass spectrometer for better chromatography analyses.
Waters’ new QDa Detector gives users the power of mass detection for chromatography analyses without the cost, complexity or hassle.
As helium prices go through the roof, NIST embarks on an ambitious recycling technology.
Impacted by advancing instrumentation and techniques, column technology must evolve to keep up in the UHPLC and biopharma world.
Tobacco is traditionally a complex sample, but the team of QuEChERS, GCxGC TOF/MS and dispersive solid phase extraction cleanup can easily and accurately perform analysis and separation.
Tosoh Bioscience has added to its line of size exclusion high performance liquid chromatography (HPLC) columns for the analysis of monoclonal antibodies (mAb). The silica-based TSKgel SuperSW mAb HTP column (HTP for “high throughput) offers high throughput separation of the dimer and monomer of a mAb in a reduced analysis time.
Restek’s Raptor LC columns advance the evolution of superficially porous particles. Superficially porous particles (commonly referred to as SPP or “core-shell” particles) boost column efficiency and reduce analysis times.
JM Science offers a complete line of Shiseido HPLC Columns in its 2013 catalog. The CAPCELL PAK is an epoch-making HPLC column that integrates the excellent separation performance of silica-based, polymer-coated packing material.
Agilent Technologies’ new J&W gas chromatography columns are designed for energy and chemical exploration, processing and distribution applications. The columns include extensions to the PLOT PT product line with aluminum oxide and molecular sieve stationary phases, as well as DB-sulfur SCD (sulfur chemiluminesence detection) columns that increase system reliability and detection stability.
Advanced Chromatography Technologies’ has released its ACE CN-ES UHPLC and HPLC columns. These columns incorporate the latest in stationary phase design, combining CN polar selectivity with enhanced hydrophobicity, enabling the benefits of both interactions to be fully exploited.
Restek’s QuEChERS performance standards kit for initial method evaluation and ongoing performance validation allow food safety laboratories to simplify standard preparation and better ensure data quality. The kit was specifically designed to provide low-cost entry level mixes for food safety and contract laboratories that want to evaluate the QuEChERS extraction approach for determining pesticides in fruits and vegetables with GC and LC instrumental methods.
Spinnovation’s Elemental Analysis for cell culture media and raw materials offers a more complete analysis platform for cell culture. The analysis service uses inductively coupled plasma optical emission spectroscopy (ICP/OES) to test samples for up to 30 elements and trace metals, at levels as low as parts per billion (ppb).
VICI’s Pulsed Discharge helium ionization Detector extends the detection capabilities of the Agilent 6890 and 7890 gas chromatographs. The basic operating mode of the unit can replace many of the detectors currently used by GC manufacturers.
The Thermo Scientific TruScan GP offers pharmaceutical identification capabilities for pharmaceutical manufacturers in emerging markets. Pharmaceutical manufacturers and regulatory agencies around the world can use this cost-effective handheld Raman analyzer to quickly identify raw materials and confirm the authenticity of finished products.
