Are you interested in GPC/SEC technology and want to deepen your knowledge? Then the following two classroom training courses at our Agilent University are just right for you.
Note: The course is in German, with English slides. The course will be held…
HPLC 2024 will be held from July 20-25 , 2024 in Denver , Colorado this year. We will host our Reach Your Summit Reception which will be held on July 23 rd from 6pm – 8pm local time at Earl’s Kitchen + Bar. At this event, you will find different areas…
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…
Hello,
Although limited Chemstation does save some confg files and other information at the OS user level, so creating a new OS user would clear those files. Also, some printer configurations can cause problems with Chemstation as it tries to read…

...
This Information Applies To: Agilent UV and RID detectors
Issue
A clogged flow cell causes high backpressure. The clog can be removed by flushing the system with solvents at high pressure. If you suspect a clog or experience high backpressure due...
This Information Applies To: Agilent G1312X and G7112X binary pumps.
Issue:
A blockage before the pressure sensor, e.g. in a pump head, will not give a high pressure or overpressure system error. Instead, the pump may show one of various error messages...
This Information Applies To: Agilent 1100, 1200, 1260 LC Pumps.
Issue:
The following procedure allows the cleaning of residue from the pump's check valves, often caused by polymerization of aged acetonitrile or salt-based solutions that may prevent...
This Information Applies To: Agilent LC Systems
Issue
After analyzing dirty or concentrated samples, some sample compounds may retain in the column and other parts of the HPLC system. If the column re-equilibration after each run is not enough to...
