Estimating uncertainty has become one of the most important metrological concepts in analytical science over the last 15 years to such an extent that some authors consider a result useless or invalid unless it is accompanied with an uncertainty statement. This article describes how to estimate uncertainty in chromatographic analysis and how laboratories can calculate it using data from the method validation process.
Researchers Edward Staples from the US measurement technology company Q&A Solutions (Westlake Village, CA) and Shekar Viswanathan from the National University (San Diego, CA) have developed a new method for detecting contraband in cargo containers using urface acoustic waves (SAWs) and a capillary-based gas chromatograph column.
Shimadzu has been awarded the 2008 Frost & Sullivan European Mass Spectrometry Product Line Strategy Award.
Scientist Cornelia Kasper and colleagues from the Gottfried Wilhelm Leibniz University of Hanover (Hanover, Germany) thought that a liquid chromatography method with short monolithic columns would be a quicker alternative to measure proteins in culture while also having had the potential to separate different proteins.
Electronic Sensor Technology (Newbury Park, California) has developed a method for detecting and measuring melamine in milk powder using the company?s zNose electronic nose that requires no sample preparation.
Researchers from National Tsing Hua University (Hsinchu, Taiwan) developed a dispersive liquid?liquid microextraction (DLLME) method based on solidification of a floating organic drop and combined it with gas chromatography with either electron-capture or mass spectrometry detection.
A research group from the University of La Laguna and ICIA (both in La Laguna, Tenerife, Canary Islands, Spain) used multiwalled carbon nanotubes as a solid-phase extraction (SPE) medium for extracting eight organophosphorus pesticides from various commercial apple, grape, orange, and pineapple juices.
PerkinElmer, Inc. (Waltham, MA) announced the acquisition of Arnel Inc. (Parlin, NJ), a provider of custom engineered solutions for gas chromatography applications in the petrochemical, food and beverage, and industrial hygiene markets.
Researchers from the University of Barcelona (Barcelona, Spain) and Arboriculura Mediterranea Mas de Bover (Tarragona, Spain) implemented a factorial experimental design in developing a solid-phase microextraction (SPME)?gas chromatography (GC)?mass spectrometry (MS) method to analyze volatile phenols in virgin olive oils.
Thermo Fisher Scientific Inc., (San Jose, CA) has launched a program focused on assisting government and commercial food testing laboratories in the development and implementation of methods for the analysis of melamine in food products imported from China.
Researchers from Jagiellonian University (Krakow, Poland) used pH-sensitive chitosan microspheres that had been cross-linked with genipin ? an aglycone derived from a compound present in gardenia fruit extract ? to bind heparin at pH levels comparable to that found in blood.
Scientists from Lanzhou University (Lanzhou, China) developed an automated on-line method for determining substituted aniline compounds that consisted of in-tube solid-phase microextraction (SPME) with oxidized multiwalled carbon nanotubes coated on the outside surface of the SPME fiber, which was inserted into PEEK tubing attached to a six-port injection valve.
Thermo Fisher Scientific (Waltham, Massachusetts) announced that it will be the lead sponsor of ?Bioavailability, Bioequivalence, Pharmacokinetics and Beyond,? a workshop and conference to be held in Ahmedabad, India, December 1-3, 2008.
Researchers from Hebei University and Baoding University (both in Baoding, China) used water-compatible molecularly imprinted polymers as a sorbent for solid-phase extraction (SPE) of nine quinolones from urine samples.
