Hi everyone,
we wanted to clean the ion source for the first time.
The videos were unfortunetly not very helpfull. We lowered the temperature of gas and sheath gas and let it cool to 25°C, and then lowered the flow rate of the gas. if we would put…

Hello Ruthvn Please share some photos of your chromatograms and check for void volumes in capillary connections. Once the issue occurs, does it keep occurring for subsequent injections or do the resolution and acceptable peak shape come back in later…
Hello LCMSvsLCUV Would you be able to share more details about what you are trying to achieve please, including the instrument set up, application, analyte of interest and the column part number?
We are having a issue clearing up these valleys/dips after our peaks of interest. So far we have confirmed no leaks up to the column (pressure and leak test passed), new column, new guard column, new mobile phases, new standards, and several purges through…
Hello,
I will assume you mean you are using the backup restore tool for CDS 2.4 not the ECM XT import scheduler. If you have setup an import scheduler task to back the ECM-XT system up that would be self-referential and would not actually back anything…
