A few things to check: - use the latest version of LabAdvisor (currently B.02.14 SP1) - thoroughly purge the entire pump with the selected solvent - double-check or replace the blank nut - using a piece of tissue, check all physical connections for leaks…
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…
I have a simple syntax question (I think). I am trying to get the statement below to work, but am having a problem with the syntax at the Select statement. Any advice would be great: I tried this and it is failing at " x. GetCustomField ( "Sample Weight…

Hi mazarakis, I do not see an advanced operation manual published as of yet. I have attached the 8890 Operation Manual in case this helps. Regards James
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 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 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…
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 dhanong, If you have 10 GC at 2 fids per GC all on at the same time using 40ml/min of H2, thats only 0.8litres per minute. I am not sure what the max would be, but I have seen that many GC on 1/8th inch line. The tricky part is when you get to the…
