The vials and caps are the same ones we have been using for years now; they are your standard 2mL GC/LC vials. I opened up LabAdvisor and ran the gripper test. It failed to release the vials even after re-initialization. I removed the gripper caps, wiped…
Agilent has identified a defect that can cause Quant to apply incorrect ISTD (Internal Standard) Concentrations when applying different Quantitation methods to a given batch.
This can cause invalid or incorrect calculated concentrations for target analytes…
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…
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…
