I believe the features you're describing are accessed by selecting "Set Background Chromatogram" under the "File" menu in the acquisition window, and turning on "Overlay Mode" under the "File" menu in the chromatogram window. In the first case, a previous chromatogram will be displayed during acquis...

I see how that would be easy to implement, however when I download a new version and my browser asks where to save, I just append the version number to the file name myself. I have a directory full of files with names like "Clarity Install 4.0.1.exe" and so on.

I just upgraded one of my Clarity stations (2 instruments) to the latest version (4.0.1.700). Both instruments use Valco selector valves. Since the upgrade I've had some strange behavior from both instruments. For example, I have an instrument with one valve associated with it. If I try to send a me...

I haven't installed the beta yet to see if the changes to the FC GP module make this a moot point, but I noticed that in the method setup dialog for the FC GP module, the start time must be a value less than 1000 minutes. It would be nice to be able to set that value higher, for example when running...

Have you had a chance to work on a driver for the Foxy 200 Fraction Collector? If so, I'd be glad to help you test it out. I've recently set up another Foxy 200 on a Clarity station using batch files called from the event table to send commands over the serial port. It works, but a problem sometimes...

I'm using a method which involves executing multiple batch files from the event table. When these files are executed, the command prompt window briefly appears until the batch file finishes. I am concerned about accidentally closing this window or entering text accidentally if it pops up at the wron...

I had a similar experience with a different chromatography data system. It would sometimes shut down on overnight runs, and always around the same time. Mr. Mentlik gives good advice when he says to check the automatic update settings first, as that was the cause of the problem in my situation. If t...

Thanks for looking into the problem for me. I've put together the files requested, and will send them to you shortly. I've included two chromatograms. The shorter of the two is from the instrument I believe to be causing the trouble, and the longer is from another instrument and was truncated at the...

On a few occasions recently I've received an error at the end of an analysis on one of my instruments. It occurs with both single analyses as well as at the end of steps in a sequence. The error message says (roughly) "Cannot create raw file C:\Clarity\tmp\$ch3temp.raw". I'm not sure if it is always...

I finished re-installing Clarity (including reinstall of the drivers). This seems to have solved the problem. The "Parameter" field has re-appeared in the event tables of all my methods. This problem appeared immediately before the failure of the power supply in my PC, and remained after I replaced ...
