Virtual Column - 2

Virtual Column is an option available for the Chromeleon Chr om Management System software (release 6.6 and above). O ST > Optimize Whether you work with "standard" IC methods or develop your own methods, optimizing separa- tions for your specific applications can save timeand deliver better results. Unfortunately, seekingthe best column and separation conditions for an IC analysis has traditionally been a gamble. You had to guess where to start and which parametersto vary, never sure if you were headed in the rightdirection. You had to spend hours generating chromatograms, consuming...

EPARATIONS > and choose the Dionex column and eluent systemyou want to model. Virtual Column displays thechromatogram you can expect to obtain, togetherwith a resolution map indicating the eluent condi- tions that will produce the best separations. Solutions to Cover Your Application Needs Virtual Column models all of the most popular Dionex anion-exchange and cation-exchangecolumns, using hydroxide, carbonate/bicarbonate,and methanesulfonic acid eluent systems. Retention data for hundreds of analytes, obtained from columns carefully selected to be statisticallyrepresentative of...

2 A 8 SMinutes In just a few minutes,Virtual Column identifiesgradient conditions on the same IonPac AS18column that allow separa-tion of all componentswith baseline resolutionand a run time of only 21 minutes. By switching to a gradient eluent, Virtual Column finds conditions that even further reduce analysis time, while maintaining resolution above your specified minimum. Using a highly concentratedeluent of 50 mM on anIonPac AS18 column elutespolyphosphates isocratically,but retention times are long,peak shapes are poor, andother components are severely impacted. 153 6791011 Ֆ 1 7 5 10...
