I am using Agilent MassHunter Qualitative Analysis B.07.00 and NIST MS Search 2.2. I try to identify the peaks using NIST library. This is the mass spectrum of a peak of interest: But when I tried to do NIST search, a completely different spectrum appeared in NIST, but with the right retention time showing as the title of the spectrum: If I… Show more
Hi Howard_sanford, Thank you a lot for your time spending on this issue. Unfortunately, my problem remains the same. In our company, all my colleagues’ computers are running Windows 10, and they don’t have any problem using MassHunter and NIST. So I guess the operations system should not be the issue. So I tried to follow your instruction…
The sensitivity of GC-FID 7890A has low sensitivity.
Followed the LAN setup in the manual, yet all I get is Powerfail. Using Chemstation version B.05.04 (which is supposed to work on Windows 10).
Hi! Due a change to OpenLab CDS C.01.10 the setup of the sequence changes. For the old Version i setup a Sequence with a macro using the commands: SetTabVal _SEQUENCE, T$, R, "Vial", Vial Where T$ is the "SeqTable1" od "SeqTable2". So i can set up a list for front and back and then start the sequence. In Version C.01.10 the Sequence is… Show more
Hi all, We utilize various different methods and prefer to queue sequences up whenever multiple methods are needed for our analyses. Problem is, whenever the 1st sequence is complete, the instrument sits idle and does not start the next (queued-up) sequence. It appears that you have to click the save icon (floppy disk) to get it started,… Show more

Hi, I am currently using a 1260 ALS autosampler (6 port valve) on my HPLC system. However, every time I inject sample, or simply run my method at "mainpass" mode for the injection port, I can see a significant pressure drop and also leaking from the needle seat. I just changed a new needle seat, needle, rotor seal and isolation seal. But it is… Show more
