I could use some resources on manual tuning for ICP-MS systems. I'm a relatively new user, and I'm disappointed at the seeming lack of useful information available through Masshunter Help, Agilent user manuals, or online.    Specifically, I'm looking for resources pertaining to how lenses, plasma settings, and various other tune parameters … (Show more)

I vented the system in order to clean the spray chamber, nebuliser, and transfer ion capillary. After completion, I started a pump down sequence and left the system over the weekend. The rough vacuum is at ~2.6 torr and the high vacuum is 0.005 mtorr. According to the help section on chemstation the rough should be 1.5 to 2.5 torr and the high <… (Show more)

I did disconnect injector… (Show more)

A mailing that was sent last week included a note about doing Semi VOA's with an 8890/5977 system. It used the 8270 column and a 9mm drawout. We had a power failure last weekend and I lost the note as I had it open, not saved!  Can anyone point me in the correct direction, as I couldn't find it on the web site.   Thanks John

Hi, I am putting together a proposal for the owner of the company I work for to make flavors. I cannot purchase the GC/MS system until I can determine if I can use an alternative carrier gas with good resolution,selectivity, etc. We are looking at buying 7890A GC with a 5975C msd as a detector. In the past at another company I used same equipment… (Show more)
