Hi, We have UV-Vis DAD (G4212B, 1260 infinity Agilent). After turning on the UV lamp and waiting for the UV signal to become stable, we have noticed a continued increase in the board temperature (while constant optical unit temperature) for more than 2 hrs as well as unstable UV signal. Your help with troubleshooting the problem will be… Show more

(to sheydashakiba) 10 hours ago (Show moreShow less)The first 30 min are fully uncontrollled heating. A drift will be seen on the baseline. Then the control mechanism kicks in and the baseline will become more stable, but it will take some time. I would not run any precious sample within the first hour. Some applications are more sensitive to slight changes in temperature, so you want to wait for…

I've calibrated the temperature on a 6890 and 7890 inlet and also calibrated the flows. Is there a way to adjust the temperature on an Intuvo oven? We have a calibrated thermometer and the oven is reading 4°c lower than it should. Any help would be appreciated thanks.

Hello, I got 2 Questions. First one: I got in the method from our 6890 the parameter "Vent Flow" It has the value 0.1. On the A7890 this value is not present anymore. 2nd Question: There is a new parameter "Septum Purge Flow " I cant turn it off. Whats the default Value on the 6890 ? What these settings do ? Regards White

I am using an agilent 7890B GC ECD system When i tried to open the Open Lab control panel, " Autostart Macro failed error#41063" was displayed and the control panel did not open. I tried your online solutions for similar error 16289 (Renaming for config files with extension .old and also deleted user.config file). After I started open lab… Show more

The ISTD of my 7700 is fluctuating immense but only in no-gas mode, in He-mode is everything fine with the stability-graph. I have a recovery from about 20 to 180% with all 3 ISTD’s (Sc,In,Lu), they have the same deviation in the same way. It happens spontaneously with every kind of sample, even with a blank. I’d be happy if someone has any… Show more
The sample uptake is 30 at a speed of 0.3 and the stabilization time is 30. I have tried a uptake time by 45 and stabilization by 25, because my second 7700 has this settings and works fine but there was no improvement. The Problem with the instability exists around 2 years so the tubing, nebulizer and cones were changed multiple times, while the…
