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.
On-site hydrogen generators are safe, reduce run times and improve gas chromatography results.
Acetyl fentanyl overdose deaths have recently been confirmed in Pennsylvania. If states observe clusters or increases in illicit opioid-related overdoses above expected levels, acetyl fentanyl could be involved. CDC encourages laboratories to use an ELISA test to screen specimens from suspected illicit, nonpharmaceutical opioid overdose deaths. If an ELISA test is positive for fentanyl, CDC recommends confirmatory testing by GCMS.
Which comes first—is it the rapid pace of life science that drives new chromatography developments or vice versa?
Through an agreement with Zoex Corp., JEOL’s AccuTOF GCV 4G high-resolution time-of-flight mass spectrometer system now comes with Zoex’s two-dimensional gas chromatography (GC x GC) technology.
FTIR has emerged as a viable alternative to gas chromatography for the qualitative and quantitative analysis of gases. Qualification and quantitation are performed from the wave numbers of the characteristic peaks and peak intensities of the measured gas.
A multitude of performance factors including dense gas CO2, small particle columns and mass spectrometry with UV detection are speeding up chiral separation methods development. Chirality plays a critical role in drug efficacy because enantiomers may have vastly different biological, pharmacological and toxicological properties.
Concurrent solvent recondensation–large volume splitless injection meets the EPA’s low detection limits for water analysis, while also reducing sample preparation time by more than one hour. This injection method produces a pressure surge from the vaporizing solvent, forcing the analytes onto the pre-column.
Agilent Technologies’ 2013 Essential Chromatography and Spectroscopy Catalog is divided into five sections to help the reader easily navigate the company’s growing portfolio, which includes general chromatography, sample preparation, GC and GCMS, LC and LCMS and spectroscopy. This edition of the catalog contains CrossLab products for use with other manufacturers’ instruments. It also includes details about electrochemistry meters and supplies, Captiva syringe filters, Ultra Inert and application-specific GC columns, LC biomolecule and Poroshell 120 columns and OneNeb nebulizer for ICP-OES and MP-AES.
Defiant Technologies’ handheld, portable FROG-4000 Gas Chromatography system operates on batteries and uses ambient air for the carrier gas, allowing for easy and rapid analysis of volatile organic compounds (VOC) in the field in about 5 min. The instrument uses micro-fabricated components to achieve a light weight and robust form factor.
Cerilliant offers Certified Spiking Solutions of nicotine metabolites norcotinine and trans-3-hydroxycotinine, as well as nicotine nitrosamines NNN, NNK and NAB at concentrations of 1.0 mg/mL in methanol for each solution standard. These certified reference solutions can be used as Snap-N-Spike starting materials in the laboratory’s matrix of choice for preparation of calibrators and controls in nicotine testing and other clinical or diagnostic applications by LCMS or GCMS.
ALMSCO International has launched a website focusing on BenchTOF-dx, its time-of-flight mass spectrometer for GC, providing the analytical chemistry community with a valuable online resource. Designed to offer easy navigation, the site enables visitors to gain much faster access to a wealth of information on the company’s products, applications, technical notes, scientific posters and video tutorials.
PerkinElmer’s two hyphenated thermal analysis units are designed for the accurate characterization and analysis of inorganic materials, polymers, geological materials and oils. The TL-9000 offers an innovative accessory that enables hyphenation, which facilitates the collection of evolved gases from a thermogravimetric analysis (TGA) or STA and then transfers sequentially to both a FTIR and MS or GCMS.
SGD’s 913 Series semi-automatic changeover manifold provides the benefits of many higher-cost models at an economical price. Constructed of high purity components, these changeovers are suited for use in both high purity and general purpose applications.
The latest advancements in time-of-flight mass spectrometry have allowed the technology to easily tackle day-to-day analysis of complex samples by GC. On the face of it, time-of-flight mass spectrometry (TOF-MS) ought to be more popular than it is.
The need for good gas hygiene is important to avoid risking the integrity of instruments, as well as to produce better, more productive chromatography. Ensuring gas hygiene is one of the most important steps researchers can take to optimize the performance of GC or ICP systems. Impure gases can cause installation delays, premature instrument failure and flawed results.
NASA's Curiosity rover has a compact GC system for analyzing rocks, while new GC systems on earth work with increased sensitivity and accuracy. The automated sample analysis at Mars (SAM) module is just one of a dozen instruments contained in NASA's Mars Science Laboratory (MSL) that are mounted on the Curiosity rover that landed successfully on Mars on August 5.
Shimadzu’s GCMS-TQ8030 achieves high sensitivity specification for multiple reaction monitoring (MRM) measurements by GCMS/MS, as well as for scan and SIM measurements by GCMS.
Shimadzu UK has released the OPTIC-4 Multimode Inlet for Gas Chromatograph Mass Spectrometers to address the growing R&D demand for a single GCMS system that can accommodate multiple analysis tasks.
