COVER STORY
NEW & NOTABLE AT PITTCON 2006 INSTRUMENTATION AND MORE
Pittcon Editors' Award Winners Thermo Electron showed its LTQ Orbitrap hybrid mass spectrometer, which took home the Pittcon Editors' Gold Award. Unveiled in June 2005, the LTQ Orbitrap is touted as "the first new mass analyzer to be intro duced to the market in over 20 years." The instrument, pictured on page 46, uses the Orbitrap, a type of Fourier transform mass analyzer that radially traps ions around a central spindle electrode, as the detector for ions produced in the Finnigan LTQ linear ion trap mass spectrometer. The combined instruments, linked by an intermediate stor age trap, provide for fast, sensitive, and re liable mass spectrometric and tandem MS analysis of compounds in complex mixtures for small-molecule research, drug discovery, and proteomics and metabolomics applica tions. www.thermo.com Chata Biosystems launched the Chem+Mix Automated Solution Preparation System, which won the Pittcon Editors' Silver Award. The computer-controlled system
fully automates accurate mixing and p H adjustment of 200-mL to 2-L volumes of solutions made from up to six different start ing components. The Chem+Mix system is compatible with Chata's Chem+Nect pre
packaged reagents and is designed to make HPLC mobile phases, buffers, blended or ganic solvents, and aqueous solutions. Metrohm-Peak, in partnership with Chata, also introduced the Metrohm 845 Eluent Synthesizer for ion chromatography, which uses the Chem+Mix technology, www.cha tasolutions.com, www.metrohm.com Cerno Bioscience debuted its MassWorks postacquisition software that improves the signal-to-noise ratio, peak shape, and mass accuracy of data for any mass spectrometer. MassWorks, which received the Pittcon Edi tors' Bronze Award, uses novel MSIntegrity mathematical calibration technology to pro vide up to 100-times improvement in mass accuracy for low-resolution instruments and three-times or greater improvement for high-resolution instruments. Targeted for pharmaceutical and biotech research, the software lowers detection limits, reduces the need for constant instrument retiming, and reduces the need to repeat experiments on higher resolution instruments, www.cer nobioscience.com
