INDUSTRY PRODUCTS New Harvard Peristaltic Pumps Harvard Apparatus announces the new Harvard Peristaltic Pump series. These remote-controlled, programmable peristaltic pumps offer unparalleled accuracy, reproducibility, and ease of use over a broad range of flow rates. key Benefits: * Remote-controlled design and sealed pump head make this pump ideal for use in incubators and fume hoods * Interchangeable pump heads allow for economical ease of use over a broad flow rate range * Easy to use with pre-programmed profiles for Constant Flow, Flow Ramps, Pulsatile Flow, and Concentration-based Fluid Delivery * A library of tubing sizes stored in the pump’s memory minimizes setup time The Harvard Peristaltic Pumps consist of a control unit, tethered pump head, cartridge/cassette and some sample tubing. The pump can deliver solutions over a range of flow rates from 0.001 to 1,500 ml/min depending on the pump head used. The pump will automatically rotate at the proper RPM for the tube selection and flow rate chosen. To further increase the accuracy, Harvard Peristaltic Pumps offer a rapid calibration routine to further optimize flow accuracy by entering a measured volume of fluid collected. The Harvard Peristaltic Pumps have advanced user options and other capabilities, including: * Remote initiated start/stop times * Communication with external devices through 15-pin I/O * Constant pressure through BNC * Single channel or combined channel mode for setting flow rate * Timed Dispense: dispenses for a fixed time at a set flow rate * Volume Dispense: dispenses a fixed volume * Foot switch control option * Analog control option * Bi-directional delivery Harvard apparatus +1 800.272.2775 Holliston, ma www.harvardapparatus.com Charge Detector for Ion Chromatography, Co-developed by UT Arlington and Thermo Fisher Scientific, Receives Patent The University of Texas at Arlington and Thermo Fisher Scientific Inc., announced that they have been granted a United States patent (#8,293,099) for a novel charge detector for ion chromatography that they developed together. The invention has been commercialized as the Thermo Scientific Dionex QD detector, which was introduced in March 2012 at the Pittcon Conference and Expo. The detector, used in combination with the Thermo Scientific Dionex ICS-4000 ion chromatography system, is well suited for analysis of polyphosphates by environmental testing laboratories, organic acids in the food and beverage industry and amines in chemicals. It offers an easy-to-use alternative to traditional conductivity detectors for peak identification, peak purity analysis and quantification, while generally providing more information. The charge detector was invented by UT Arlington chemistry professor Purnendu “Sandy” Dasgupta, along with Bingcheng Yang of his research group and kannan Srinivasan, technical director for Dionex Corporation, a subsidiary of Thermo Fisher Scientific. The patent is jointly owned by Dionex and the UT System. Dasgupta has received numerous national and international awards for his work in ion chromatography, including the prestigious 2012 Dal Nogare Award, given by the Chromatography Forum of the Delaware Valley, and the 2011 American Chemical Society Award in Chromatography. Dasgupta has been awarded more than $18 million in research grants and is the author of more than 400 scientific papers. The latest patent is his 23rd in the United States. “we are particularly proud that this innovation has made its way into the marketplace,” said Carolyn Cason, vice president for research at UT Arlington. “One of the hallmarks of a vibrant research university is the ability to team with industry to advance scientific application, and this is what Dr. Dasgupta has done.” “we see this as a game changer,” said Chris Pohl, Thermo Fisher vice president, chromatography chemistry. “Charge detection, when combined with suppressed conductivity detection, can be used as a confirmatory tool or as a complementary detector to provide additional analytical information.” The Dionex QD detector uses a membrane-based technology and detects ions in proportion to their charge and concentration. This permits reliable quantification of known and unknown compounds with a single standard, as demonstrated in UT Arlington and Thermo Fisher Scientific labs.
