Please check your data files and make sure the solvent peak is completely excluded . I have found that some data files I cannot detect ANY analytes of interest in Optimizer, even though I can identify them in standalone Unknowns Analysis. Without fail…
Also, please make sure that a default printer is configured in Windows. If no default printer is configured, the following problems may occur: - Printing of a report preview will fail. - the 'Copy To Clipboard' menu will have an error - the 'Custom Report…
I have a 5977B MSD that is experiencing a vacuum failure after a scheduled shutdown for renovation work in our facility. Work was completed and now we are restarting the system. At first we though it was the roughing pump, but we have bypassed the remote…
The only change we made was to install a DB-VRX column. It goes to the Agilent splitter mounted inside of the oven, then goes to the FID and MS. When I inject a sample, the FID and MS chromatogram peaks follow each other perfectly. After the injection…
Hi Everyone, I'm operating our Cary 3500 and I am helping with an assay being put together based on competitive binding. Because of the competitive binding, the primary and reliable peak *decreases* in size rather than increasing as the concentration…
Im running on an old GCMS with headspace sampler. Its been failing during runs recently. The logbook shows that the oven is not ready at run time for each sample. After about 10 samples it just stops collecting data. The headspace continues to cook all…
Does anymore have./know of a macro for Agilent Enhanced Data Analysis Software (MSD Chemstation G1701FA F.01.03.2357) that enables the integration of a file (FID and TIC using the ChemStation integrator) to be saved so when you re-open the data file you…
Fortunately yes, so I am covered from that point of view The GC over here is a combo MS-FID machine which can be build to either MS of FID mode. It was in FID mode the last couple of days. Just rebuild the GC to MS mode, but I didnt perfom a full-on cleaning…
jhagel is correct, do not change PE (Yellow) to PTFE (black) seals in round headed pumps (1290 Infinity and Infinity II as well as G7014C). Both seal types have benefits and downsides: While the black seals are generally better when using them with reverse…
