The latest Technical Hichrom Chromatography Columns and Supplies Catalogue (v9) contains a wealth of valuable information and advice for the chromatographer and features over 100 LC column brands and 35 chromatography suppliers.
In addition to HPLC, UHPLC and superficially porous particle columns, the latest catalogue contains details of SFC, GC, SPE, TLC, Flash, CE, LC-MS and GC-MS products. Vials, syringe filters, tubing, fittings and other chromatography accessories are also included. This catalogue includes a comprehensive and invaluable technical summary section with a wide range of LC and LC related topics, plus detailed overviews on C1 to C30 columns and Polar Embedded, Wide Pore, HIC, Phenyl, PFP, Polar Bonded, HILIC, Silica, Ion-Exchange, SEC, Affinity and Chiral phases, all with helpful column recommendations.
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....
This new autosampler (Thermo Scientific TriPlus 100 LS Liquid Autosampler) performs liquid injections in a completely automated and reliable manner, regardless of the matrix or the selected technique. With the addition of optional accessories, the system is capable of automating sample preparation steps such as standard dilution, standard and internal standard addition, and vortexing. The autosampler can handle almost any type of liquid samples, including highly viscous or very volatile solvent samples...
Scientists using gas chromatography (GC) can enjoy a number of new options with the Thermo Scientific TRACE 1300 Series GC system, designed to conserve helium, permit use of multiple detectors simultaneously, automate sampling gas workflows, and perform flame photometric detection. New options for the TRACE 1300 Series GC platform include...
More than any previous improvements and enhancements, the new Version 4 adds DirectRead™ data support for three high resolution MS systems: Thermo Orbitrap or FT ICR MS, Agilent TOF, and Waters TOF, while expanding unit mass resolution direct support to Agilent MassHunter and Advion CMS. For the first time, MassWorks now enables elemental composition determination in the absence of an observable monoisotope peak or in the presence of larger-than-usual mass errors. In addition, a fully automated calibration feature, AutoCal™, is now available for out-of-box accurate mass analysis with GC/MS...
