There is no written maintenance procedure for the MS40+ maintenance kit.
Here is an exploded view of the pump:
Here is the parts breakdown for the maintenance kit:
I've been doing 525.2 for close to 16 years, and lately been having issues with perylene d 12, and triphenyl phosphate failing the +/- 30% of targeted concentration. I don't think the issue is due to my sample concentration step, as the nitro xylene recovers…

Hi David, this option exists already in MH 4.3 and is called Intelligent Sequencing. It is an additional software package, not included in basic MH. You can buy a license key and unlock its features. This is a very powerful software tool which increases…
We're attempting to install MassHunter Workstation Quantitative Analysis Reporting B.07.00 but it keeps failing with an Error: Unable to get the Add property of the AddIns class about halfway through the process. All other software and reporting has installed…
Hi Lorelei, In order for me to fetch correct information could you list model numbers of tower and controller, i.e. 7683 ALS tower. Meanwhile I was checking for different error messages and couldn't find Radius home failed. If error is still present could…
I am currently trying to setup a GC system and am having issues with MassHunter Acquisition. I am trying to setup a parallel system to one that we are currently running. The new system is 6890N/7697A HS, it does not have a MS. I am trying to use MassHunter…
