I would like to know what types of Video tutorials or Instruction documents you would like to see on Agilent Community. These can be for OpenLAB CDS Chemstation or OpenLAB CDS EZChrom.
I would like to see a video on Internal Standard Calibration and Quantitation for OpenLAB EZChrom
I would be very interested on a tutorial for obtaining the parameters for system suitability such as tailing factor, plate numer, among others in a report format for OpenLAB Chemstation
Hi Andrea, I hope I can provide some help.
In OpenLAB ChemStation (independent of which revision you have), you can obtain suitability results through either Classic Reporting or Intelligent Reporting. The former is the legacy reporting style that has a bit less flexibility than Intelligent Reporting but prevails in our new ChemStation revisions. For system suitability, I would say both are fairly easy to implement.
First, you would want to load your desired data result set (typically located in a subdirectory under \Chem32\[N]\Data\, where [N] is the instrument number, likely 1) and make sure the sequence method that's loaded is your preferred analysis method. Some of the suitability preferences you choose are method settings, so which method you load is important.
To see a Classic report featuring the types of parameters you're referring to, you could choose either Performance or Extended performance in the Report Style dropdown menu found in the Report > Specify Report window. If you want the report to identify which values exceed upper and lower limits that you define, you can use the Report > System Suitability > Edit Performance Limits dialog box. This is only used for Classic Reporting. Values calculated for a peak that fall outside the ranges defined in this dialog box are indicated in the report by: > (Value exceeds upper limit) or < (Value exceeds lower limit). These values are only calculated if you select a Performance report style in the Specify Report dialog box and generate a report. Below are your choices:
The Performance report displays results according to the limits specified in the Edit Performance Limits dialog box of the Report > System Suitability menu. For uncalibrated methods (i.e., methods without a calibration table), the report includes the peak number, retention/migration time, peak area, peak height, signal description, true half-height peak-width, symmetry, k', efficiency (plates) and resolution for each peak. For calibrated methods, the report also includes the compound name and compound amount; resolution uses the calculation stipulated by the EP, BP, JP and DAB for each peak.
The Extended Performance report displays an extended report with all the parameters from the peak performance calculations and individual plots of each peak. This report type includes only calibrated peaks. In addition to the parameters printed for the Performance report style, the start and end peak retention/migration times, skew, excess, peak width, USP tailing factor, time interval between data points, number of data points, statistical moments, plates, plates per meter, selectivity and resolution of each peak are displayed. The peak width, plates, plates per meter, selectivity, and resolution are calculated by the true half height, 5 sigma, tangent and tailing methods.
Intelligent reporting is a lot more flexible because one can much more easily modify, delete, or add elements in the report. The Performance.RDL, Performance+Noise.RDL, and ExtendedPerformance.RDL reports are located by default in \Chem32\REPSTYLE and selectable in the ChemStation software via Report > Specify Report. These reports also provide k', peak area, peak height, symmetry, peak width at half-height, number of plates, resolution, selectivity, and Signal-to-Noise (available in Performance+Noise.RDL).
Further discussion can be had about resolution calculations, Noise and Signal-to-Noise, and those subtleties are elaborated upon in the Help topics in ChemStation and in the Reference to Operation Principles manual on Disk 2 of OpenLAB ChemStation (it is a PDF called CDS_CS-references.pdf).
I hope this helps!
I would like a tutorial on Intelligent Reporting along with downloadable examples. I have found it very difficult to find information on the topic of Intelligent Reporting.
I am currently working on OpenLAB CDS Chemstation Intelligent Report videos. I will be doing short segments on the following topics, creating a report, adding a chromatogram, adding and editing a table, custom calculations, and eliminating extra pages. If you have other information you would like, please let me know.
Thank you Kim! I would also like to see how to calculate bulk properties from stored values of components such as BTU value and conversions to vol or wt % based on component density. I found this thread that covers this but would like also see a tutorial https://community.agilent.com/thread/1113#1261
This feature is not available in Openlab Chemstation or EZChrome. Agilent supports the use of Diablo EZreporter for these BTU calculations.
The newest software Openlab CDS does support the BTU calculations using a spreadsheet to hold the conversion factors.
It would be very helpful, if you give us a video tutorial, how to use the custom calculator, with some step by step examples.
What version of the software are you using?
I am using OpenLab CDS Chemstation v1.8.

As some people said before, the first idea of tutorial that reached my mind is: how to create an intelligent report? In fact, I spent some days trying to create it but I found very difficult to understand the logic of it. Please, can you also talk about how to include mass spectra in those reports? And also how to include personalized items. For example, in my lab we would like to have the amount of sample that was weighted and the amount of solvent which was employed for the dilution on the report. For instance : x mg in y mL of acetonitrile.
Second, I am also interested in a tutorial that shows all the possibilities about presenting the results. I am doing qualititative work, especially on the mass spectra. So, I would like to know if it is possible to annotate the ions and to put chemical formulas next to the ions. Also, is it possible to annotate the mass loss between two ions?
Finally, I would like to know if it is possible to create a library of mass spectra with OpenLab Chemstation. If yes, can you please think about a tutorial that explains this?
Thank you for your response. I will try to get a video basic workflow in Intelligent reporting. I will research your request for annotating the ion and if it is possible to put the chemical formulas next to the ions. There is a way to create a library in OpenLab Chemstation. I will try to do a video on that also.
