Advion Biosciences Inc. (Ithaca, New York), a developer of microfluidic sampling technology for mass spectrometry (MS) has bought almost all assets of its production supplier, Washburn Manufacturing Technologies Inc. (Trumansburg, New York) for an undisclosed amount.
Agilent Technologies has announced the presentation of the 2008 Manfred Donike Award for scientific excellence in sports doping testing to the German research scientist Ulrich Flenker, of the Institute of biochemistry, German Sport University, Cologne, Germany.
GE Healthcare recently announced its completion of the acquisition of Whatman, which is a global supplier of filtration technologies and products.
Merck KGaA (Darmstadt, Germany), a privately-held pharmaceutical and specialist chemicals company, has acquired the assets of chromatographic column developer SeQuant AB (Umea, Sweden). "[The aquisition] offers Merck superb opportunities for the future expansion of the chromatography business," said Klaus Bischoff, head of the Performance and Life Science Chemicals division at Merck.
The assessment of accuracy, which involves the estimation of precision and the determination of trueness, refers to the process of evaluating whether the results provided by analytical methods are close to accepted reference values. The different references available in chromatographic analysis and useful guidelines to perform such a comparison are described.
The potential of the time-of-flight mass spectrometry (TOF-MS) to innovate the analysis of soft drinks is described using gas chromatography (GC) hyphenated to TOF-MS and a new type of ion source, direct analysis in real time (DART), coupled to high-resolution TOF-MS. Head-space solid-phase microextraction (SPME) was used to isolate/extract volatile compounds followed by GC–TOF-MS to identify tainted compound in contaminated soft drinks. Direct analysis in real time–time-of-flight mass spectrometry (DART–TOF-MS) was also used to obtain negative and positive ion profiles of different soft drinks to determine the presence of various compounds, including antimicrobial preservatives, artificial sweeteners, acidulants and saccharides, without any sample preparation and chromatographic separation.
This annual "GC Connections" installment reviews GC instrumentation and accessories shown at this year's Pittcon and also includes some products from Analytica in Munich.
To obtain a better understanding of the challenges faced during method development and validation, the authors - in cooperation with LCGC - conducted a survey earlier this year. This column summarizes the results.
Scientists Jorn Chi Chung Yu, Garrett Lee Burleson, and colleagues in the Department of Forensic Science at Sam Houston State University in Texas have developed a new method for identifying gunshot residue without the presence of lead.
PerkinElmer (Waltham, Massachusetts) announced the "Ettre Award" to honor a young scientist in the field of gas chromatography.
Thar Instruments (Pittsburgh, Pennsylvania) has expanded their European team by four new members since the company's acquisition of Berger SFC in 2007.
Inlet discrimination is a problem encountered by gas chromatography (GC) analysts when making a split injection. It is characterized by peak response that is smallerthan expected for less-volatile compounds, and that gradually gets worse as retention time increases. The cause of this problem stems from both the sample and the injection technique. Upon injection of a sample with multiple analytes into a heated inlet, different compounds enter the gas phase at different rates. This means that a disproportionate amount of sample will be purged from the split vent.
This month, "GC Connections" presents a few of the best and worse laboratory habits.
Computerized pneumatic control adds a very capable multipurpose tool to the chromatographer's tool belt.
This month Chromatography Online's Technology Forum looks at the topic of GC and the trends and issues surrounding it. Joining us for this discussion is Sky Countryman of Phenomenex, Nicholas H. Snow of Seton Hall University, John Hinshaw of Severon Corp., and Meredith Conoley, Jason Cole, Eric Phillips, Joergen Olsson, and Flavio Bedini of Thermo Fisher Scientific, Inc.
This Tuesday afternoon session, titled "Current Status and Trends in the Application of Liquid Chromatography (LC and UHPLC) Hyphenated with Tandem Mass Spectrometry for Pharmaceutical Analysis" was presided over by Arindam Roy of Covidien.
"A bitter pill to swallow" may be an old adage, but it actually has meaning to today's pharmaceutical industry and to chemists using modern chromatographic techniques.
Being here in New Orleans, which is one of the busiest port cities in the U.S., the topic of Homeland Security seems particularly relevant. So I attended Session 1490, "Homeland Security and Forensic Analysis." It proved to be very interesting.
Pittcon has seen a lot of new products launched this year, all of which innovative in design and concept. A few new products were highlighted in Tuesday morning's session 1173: "New Product Forum: Chromatography Columns," presided over by Robert W. Baudoux from RWB Convention Management.
It seems as though Pittcon 2008 has gone by in the blink of an eye as we reach this, our final day of coverage from New Orleans. And although the long lineup of press conferences may be winding down at this point, the roster of technical sessions continues onward and will even continue into the end of the week.
A professor from the University of Pittsburgh received one of the most distinguished awards at the Pittsburgh Conference on the third day of Pittcon 2008 from New Orleans.
Well, it's Pittcon Day 2, and I followed the suggestion of LCGC Columnist John Hinshaw and attended session 410, "Food Science: UV-Vis, NIR, AA, LC, GC, and Electric Nose."
Monday's "General Interest: LC/GC" session delved into a wide array of new techniques and discoveries in the scientific and academic LC/GC communities.
The 2008 Chromatography Forum of Delaware Valley Dal Nogare Award was presented Monday morning to John G. Dorsey, the Katherine Blood Hoffman Professor of Chemistry at Florida State University, by Mike Koenigbauer, President of the Chromatography Forum of Delaware Valley.
Four years ago, problems were slightly different for HPLC users. However, one main problem remains the same and will continue to remain the same.
