Restek’s free, online Pro EZGC and EZLC chromatogram modelers have been upgraded with new functionality and compounds. Now with powerful GC-MS modeling capabilities, the new Pro EZGC chromatogram modeler is simple to use and helps labs by automatically targeting isobars for chromatographic separation. In addition, the Pro EZLC chromatogram modeler now includes a pesticides library, allowing users to easily optimize methods forthis important class of compounds. Both modelers let users simulate separations that are accurate to within 10% of actual elution times with no experimental data needed. And since modeling is done in just seconds virtually rather than taking up valuable instrument time, lab output stays high while the time and cost of method development are cut dramatically. In addition to the Pro EZGC and EZLC chromatogram modelers, free, high-accuracy method translators are also available in Restek’s EZGC and EZLC software suite.
