As long as you do not see any issues in your measurements, you can keep using the EM, until your new EM has arrived. At some point the Pulse HV will reach ~1800 V and the Analog HV will reach ~ 3300 V (if you are lucky). After that you will have to replace…
Instrument: 7890 GC modified for gas injection with a 10-port valco valve. It's dual SS inlet, dual detector FID/TCD.
I have installed some components into the AUX bracket, two heating components into AUX 1 and AUX 2, and a valve actuator in V1. Valve…
Hello,
The RI uses a lamp and since it's works on refractive index differences, it doesn't use a wavelength. The RI is what is called a "bulk" detector.
If you are thinking you can replace the lamp, it's part of the optical unit and when it fails…
Hello, my friend, After checking the logbook on the ChemStation, note that the method did not run due to an error in the G4212B detector indicating: Start Failed (temperature HW). After that, I checked the instrument with the Lab Advisor, and the Logbook…
Hello team, I wanted to consult the following: an HPLC 1260, I had to reinstall the software. Once I did it, after creating a new method and giving the order to inject, the software turns blue and immediately turns green and does not inject... After checking…
Hi, There are so many open questions, that i would ask you to run thorugh the "Troubleshooting Tool". It´s an guided pdf, which helps to identify the problem. The last performance report looks quite well, also the torch axis and the em tuning run without…
Otis,
This is the reply from Engineering:
the connection refused error indicates that the A-Plus server is not reachable, this can happen for two reasons:
The server has gone into error, in this case it is possible to launch A-plus from a dos…
Hi galderson,
that's a typical "it depends" answer. For the carrier gas line I assume you use at least a 5.5 or even 6.0 gas quality? Anyway depending on the gas quality there are different concentrations of impurities:
Now you need to…
I went back and installed a no-hole ferrule and get a passing air/water check (I assume this rules out the MS interface), but when installing a column to the MS interface with the other end capped, the air/water check fails.
