Hi, I have the same problem as well. We are using LC 1220 Infinity series. We tried flushing the system with isopropanol for 10 minutes just in case the bubbles are present. However, this does not solve the problem. The pump failed to get ready within…
Hello everyone, I would like you to help me with a genesys 30 spectrophotometer, I have a problem that says: * Zero-Order search failed
psdt: I have already changed the focus for a halogen one but it only reads from 500 nm but at 325nm it does not read…
Hi. I am having more issues with my ancient 1100 stack. I am getting an EMPV initialization failed error. As I have done some other research it says that the bar should be around 20 bar and then you can do x, y, and z to fix it. However my bar is less…
I'm trying to use the DA Reprocessor (B.08.00) to process TOF data as a batch on a Windows workstation. If there are too many features, the DA Reprocessor stops with the following error in the log: Failed to run worklist Qual: The Operation has time out…
Hi all,
New to the forum, and having a few issues with our analytical 1260 HPLC. Main problem currently is an intermittent error on the auto sampler when trying to inject samples, it doesn’t happen necessarily at the first injection in each sequence…
Which voltage test point? The sideboard is permanently damaged if the cables are connected to it while the power is on. Did that happen?
Notice in your picture above that the HED is set to On.
If the HED power supply is not functioning properly…
Have you checked that your stock standards are not contaminated and tried a second source of SIC. Do you run He in addition to nogas and does it only fail for nogas but pass in He?
I've also seen Sb stick around in the tubing, autosampler probe, and…
That's interesting. I wonder if there are any differences to be expected between a 6890N and a 7890 GC when using Chemstation on the 6890N and Openlab 2.3 on the 7890 with FID? Also, would there be any differences in the signal to noise and dynamic range…
Hello, How often does your reference amount for the compounds change? If it never changes or changes on an infrequent basis I would suggest using a constants file in custom calculator. Also we have seen syntax issues with expressions in IR when using…
