I have an agilent GC-FID 6890 i use for TPH and PAH of soil samples yet i want to calibrate it for Oxygenates in gasoline and Aromatics don't know how to go about it
A follow up question about this, if it ever occurs again. When the instrument errored out it prevented us from even initializing the instrument properly. Is it possible to auto reference even if the unit failed to initialize correctly?
Welcome everybody,
The problem occurred after updating Openlab CDS Software 2.2 Version to 2.4 Version.

Hello,
I have a question about our GC 8860, which has been experiencing some problems since I changed the valve pressure.
Although it works well immediately after the change, if I don't use the GC for a few days, the first few runs produce larger…
Hi All, I need help to fix either baseline drifted down or change volume injection of water samples in GC/FID. Specifically, I am setting up a new GC instrument for analysis of methanol and alcohols in water samples with the following conditions: - Instrument…
Hi Everyone,
Due to random readings of my samples, i ran wavelength and photometric accuracy test. Both of them fails, do i need to replace the lamp or is it because of the wavelength drive gear?
thanks.
The optional high vacuum gauge has a cable between the gauge and the electronics. It is either disconnected or the gauge has failed.
See page 125 and 126 in the 5977B Series MSD Operating Manual for instructions on how to turn it on and off.

When the tuning is done at 3200 (+) everything is fine. When I change it to tune at 1700 (+) the masses are reasonably accurate. After it gets to the third mass (620) it appears that the entire spectrum shifts by about 1.5 AMU and the tuning fails. There…
There is an SP7 switching valve on our 5110 ICP-OES The first set of triplicate aspirations of Std always ride really close to the precision limit of 2%RSD and then std#2 and Std3 are typical 0.5 or less. (ISTD Method) All of these standards are in the…
