Export method to MassLynx 4.2 version

Export method to MassLynx 4.2 version danielacgranato  2018-11-27


I was wondering if the new version of Skyline (v.4.2) allows to export SRM methods to MassLynx version 4.2. Last year I was unable to do so and I received a response that Waters was working on making it possible. As a solution to the problem I have been exporting the method to a computer not connected to the equipment (Xevo TQ-XS) and to an older version of MassLynx (v.4.1). Do you know if it is possible now to export directly to MassLynx 4.2?

Thank you very much. Best, Daniela

Hi Daniela,
I just got a similar report from a collaborator inside Waters itself pointing to the error:

System.IO.IOException: ERROR: Method not found: 'Boolean CompoundDatabaseClassLibrary.CompoundDatabase.InsertNewIonDetails(Int32, Int32, TransMode, Int32, Int32, Int32, Int32, Int32, Int32)'.

This turned out to be a compatibility issue between a DLL in MassLynx and the method export DLL Waters gives us to write their methods, which they were able to fix for their case with an updated DLL in MassLynx.

I asked what I should tell you and my contact responded:

"We looked into this earlier today and it appears that it can be case specific. The customer should probably contact her/his local support team to get an updated software version or a copy of the required library but we should probably review this on a case by case basis. I have cc-ed one of our GSS colleagues so that they are aware this as well and can provide assistance."

So, contact your Waters rep and hopefully they can get you a new version of MassLynx or a new DLL quickly.

Thanks for reporting the issue rather than just continuing to work around it. Always helps to get things moving.

The following MassLynx 4.2 versions are supported. Please note that these are tandem/triple quadrupole instrument releases. If the instrument type is not listed, please contact the local service support organization for advise.

SCN 977 (Xevo TQ-S micro)
SCN 978 (Xevo TQ-GC)
SCN 982 (Xevo TQ-XS)
SCN 989 (Xevo TQD/SQD/3100)

During installation, also specify the instrument and the TargetLynx application manager. The former is required to create a method template and the latter to populate the newly created method with the SRM/MRM transitions.
