Hi all
Apparently the engineer who did the mainboard replacement made a mistake by plugging the MCGV cable to the SSV cable, this made the valve failed to switch (EE 2040.2) and electronic fuse of SSV (EE2049.0) error always appear. It was out of my…
The GC counter rolls over at 999,999...but 100,542 is still a lot!
Great drawing, thanks. That setup makes it difficult to figure out pressures/flows. The path of least resistance is all of the 530 pieces unless the methanizer and the connection from…
The idea behind the multiple modes is to keep the flows going through your FID constant. Changing flows will change the flame characteristics and cause the baseline to shift. Some suggestions:
If your column is set to constant flow mode, use "Constant…
We have a brand new Agilent 6495 LC/TQ system with a MS 120 rough pump. We vented and shut off the instrument for building maintenance over the weekend. On startup today, the rough pump receives power (the lights turn on) but eventually fails to engage…
Is there a table / document somewhere on what Agilent GC FID flows I should be using for a particular column ? Right now I have a 7890B with a 30m 0.32 column film thickness 0.25. We use it for petroleum / Diesel Range Organic analysis with a ALS injector…
Greetings Agilent Community,
Some MassHunter 10 difficulty. I am using the same Quant method that I have used multiple times in the past to process data. This time, however, I am experiencing an error while building my calibration curve. In the Methods…
I recently installed MassHunter Workstation B.03.01 SP2 on my PC to look over some old data that was obtained on a 6540 LC Q-TOF MS system. The instrument hasn't been used for a while now, and my lab no longer has the original computer. We just had this…
Andy G. had the excellent suggestion to decrease draw speed and wait time, since we are working with methanol extract. So we halved the draw speed from 100ul/min to 50ul/min and increased the wait time from 2 to 3 seconds. For now, this seems to have…
Hi,
We currently have as GC/MS/FID using Masshunter and need to print the FID traces as a pdf scaling the y-axis to zoom in on the minor peaks showing %Area values. Is this possible within any masshunter software? I've managed to get a report showing…
I'm not experienced in FID so I'm not sure what normal bleed looks like. So yes I would trim the column and check for leaks first then a new column. Can you look back at older runs when this column was installed to see what the bleed looks like to compare…
