October 29th 2009The Pittcon Networking Committee announced the topics for the Conferee Networking Sessions for Pittcon 2010, March 1- 4, at the Orange County Convention Center (Orlando, Florida). These sessions are a networking opportunity for registered conferees with similar interests to get together in an informal setting to brainstorm and share ideas.
Analysis of Carbohydrates by Ultraperformance Liquid Chromatography and Mass Spectrometry
October 23rd 2009In this application, simple and complex carbohydrates, which are often analyzed by HILIC, are separated on the BEH Amide column and then directly detected with electrospray ionization mass spectrometry (ESI-MS) with no need for derivatization, post-column addition, or metal complexing agents.
prominence TOX.I.S. (HPLC/PDA for identification of drugs in human urine)
October 23rd 2009The Shimadzu prominence TOX.I.S. system is based on well-established LC hardware modules. Their patented flow line design and column switching procedure enable pre-treatment of urine samples with a cleaning step, rinsing to remove proteins and other urine components, and transfer of the sample onto the analytical columns for separation.
Shimadzu Upgrades GC Program with New Equipment and Systems
October 20th 2009Shimadzu Scientific Instruments (Columbia, Maryland) updated its existing System GC Program to include the GC-2014 gas chromatograph. In addition, the program now offers new streamlined systems for natural gas, transformer gas, and greenhouse gas analysis, as well as biofuels and biomass feedstock research.
A glass of red wine a day keeps the doctor away?
October 19th 2009Recently, Thermo Fisher Scientific announced the release of an application note describing its analysis of red wine using ultrafast chromatography. Red wine is a good source of antioxidants and is said to contain natural compounds that may be beneficial to human health...
A High Sensitivity UPLC/MS/MS Method for the Analysis of Fluticasone Propionate in Plasma
October 16th 2009This application note illustrates a high-sensitivity method for the analysis of fluticasone propionate in rat plasma using ACQUITY UPLC and Xevo TQ MS. High sensitivity was achieved using just 375 uL of plasma in a rapid-throughput assay. The rapid data capture of the Xevo TQ MS allowed for the narrow MRM peaks to be accurately defined and quantified.
Investigations in Improving Peptide Mapping of IgG-Based Therapeutics
October 15th 2009Immunoglobulin G (IgG)-based therapeutics are a large class of protein drugs and drug candidates that have interesting challenges in performing analytical testing, especially peptide mapping, which is necessary to fully characterize any posttranslational modifications that might occur.
