Then, the report explores the international and Chinese major industry players in detail...
This provides analysts the capability to acquire both soft EI spectra and conventional 70 eV spectra at the same time in an integrated workflow. This means that a single GC or GC×GC run can provide all the information needed to fully characterise a sample for both target compounds and unknowns. Tandem Ionisation, unique to Markes, generates two spectra from a single peak....
The new products, which form the ‘xr’ series, pre-concentrate organic vapours sampled using sorbent tubes, canisters and on-line air streams, and as well as options for automation, incorporate powerful new advances that extend the capabilities of analytical laboratories analysing volatile and semi-volatile organic compounds (VOCs and SVOCs) in air and materials....
Herolab Gmbh, the German based life science manufacturer, has recently enjoyed further success with Spot Hunter which is a robotic system integrated with a fluorescence detection unit of the automatic extraction of selected protein spots after 2d electrophoresis. This new generation of proteomic workstation offers greater flexibility than other systems, improved accuracy and reliability all within a minimal footprint. Three sizes are available including a high throughput model for gels up to 340mm x 290mm.....
The new resource, hosted at www.select-ev.com, will allow anyone to view time-of-flight mass spectra generated using Markes’ Select-eV technology. The library has been launched with the 70 eV and low-eV spectra of over 350 compounds, but will be updated quarterly with curated spectra acquired in Markes’ laboratories, as well as from Select-eV users around the world. Laura McGregor, TOF MS Product Marketing Manager at Markes International...
Time is often spent manually tightening connections between columns using a handheld tool – time which could otherwise be spent analyzing results or running more investigations. Preventing GC leaks has become a priority for researchers looking to save time and money while achieving high quality results. GC column connections leak because capillary column ferrules made of graphite polyimide blends loosen after...
Application Note 10406: Validation of GC-MS/MS for Detection and Confirmation of Low-Level Dioxins illustrates the excellent selectivity and sensitivity of this GC-MS/MS System for low levels of dioxins, even in complex matrices. Dioxins are a group of chemically-related compounds, including polychlorinated dibenzodioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), and some dioxin-like polychlorinated biphenyls (PCBs). These compounds are...
“We designed this instrument specifically for labs needing to maintain their current GC or single quadrupole GC-MS workflows while adding triple quadrupole capabilities with minimal disruption,” said Paul Silcock, marketing manager, GC-MS for Thermo Fisher Scientific. “The TSQ Duo system allows users to run their current methods and then easily move over to MS/MS analysis when the time is right for them, on a familiar system using the...
Thermo Fisher Scientific worked closely with national reference labs (NRLs) in the European Union to support the development of the new regulation, known as Commission Regulation (EU) No. 709/2014, which permits use of gas chromatograph-triple stage quadrupole mass spectrometers (GC-MS/MS) for confirmation. EU regulations previously permitted the use of GC-MS/MS only to screen samples for dioxins, a group of persistent organic chemicals that can cause...
A continuing challenge in multi-residue MS analysis is finding a sample preparation method that is as easy, fast and cost-efficient as possible. The US Food and Drug Administration (FDA) has modified a QuEChERS (quick, easy, cheap, effective, rugged and safe) protocol, which can be used to extract multiple classes of pesticides from a variety of samples. Using the EVOQ and SCION, Bruker has shown the...
It is used as a reference for the calibration of gas chromatography instruments and in other instruments that measure gas concentrations. This light-weight unit is a compact calibrator capable of delivering the precise concentrations required. A passivated Inertium® coated stainless steel permeation chamber houses the permeation device(s), with measured inert carrier gas sweeping the calibration gas/vapor from the chamber...
Pittcon, The Pittsburgh Conference on Analytical Chemistry and Applied Spectroscopy, is widely regarded as one of the world’s best trade shows for innovations in analytical chemistry. It gives attendees the opportunity to observe many analytical instrument developments, all under one roof. This year, the conference attracted 16,200 attendees, including 935 exhibitors from 32 countries across 1,763 booths....
The instrument’s broad, flexible platform allows for custom, application-specific system configurations for research, industrial, laboratory, academic, and QA/QC environments. An industrial computer provides the intelligence for the Series 8100. Navigation through program menus is accomplished using a menu driven, high resolution LCD resistive touchscreen and keypad...
During the development of spearmint and other essential oils, analytical labs are challenged by volatile sulfur compounds, as they impart undesirable odors to essential oils and have extremely low olfactory thresholds. So the detecting, quantifying, and eliminating of sulfur compounds is an important aspect of flavor and fragrance quality control work. Two species of spearmint is cultivated in the United States every year, with 1.09 million kilograms of spearmint oil produced in the U.S. in 2008....
