Hello, thanks, we are using the version A.04.09 Agilent OpenLAB CDS. And yes, RSDRtDimethyl ist the optional variable Name from the Summary Calculations (RSD from Retention Time). The RSD (from Summary Calc) Format is a Number with 3 Decimal Places. I…
I have been working on an old VWD that was not used much. After running the intensity it failed only on the minimum with a 400 of >6400 cts. So more water was flushed through it over night and the same fail reoccurred. Rebuilt the cell using the g1314…
Hi,
I am currently running a USP <467> protocol which monitors the recovery of: methanol, ethanol, acetone, isopropyl alcohol, hexanes, and toluene. I make a standard solution using DMAC with known amounts of solvent and use the same solution to spike…
Hi James, Just a followup on this. I changed the Lan adapter with G1530-62010. However, I still had a deconnexion this weekend and when sending a ping to the GC, the response time is random and high (between 1ms to sometimes 32ms). Is there anything else…
It is really rare that the transferline itself fails. It's a brazement attached to the MS with three bolts and an O ring seal. The transferline column nut threads get messed up if the column nut is overtightened. Using a 10x32 die to clean the threads…
I have recently ran two standards on the Cary 630 FT-IR using the ATR module - qualitative search. One is Heptanes and the other is N-Heptane.
I then ran four samples - three were N-Heptane, the other was Heptanes and compared them to the two standards…
You can definitely set up an intelligent report to do what you want, but there is a much easier way to do this in OpenLAB ChemStation. When you create a calibration table, ChemStation gives you an option to 'Calculate Signals Separately': When selected…
I went through everything I could find, but it appears that BootP doesn't work properly in Windows 10 and even when you follow the instructions it fails. As I mentioned above, the only way I found to get it working was to replace the JetDirect card with…
I have Chemstation C.01.08 [210]. Whenever I try to run a partial sequence, I get the 'Initialization of Sequence Failed' error message. From what I could find online, that issue was supposed to be solved in C.01.08 version of the software. I have Unique…
Hi Lakshmi, Here is the reply from our compliance group.... Traceability and Audit Trails Data are generated by the same native chromatography data system (CDS) used in the daily operation of the instrument, which controls the system being qualified during…
