Hello igorvlad
I’m sorry for the delayed reply to your message. Do you still need assistance with this? If you do, please take into consideration the notes below. However, if the issue was resolved, could you please share what the resolution was?…
Thank you for your advice. Unfortunally not only EM test failed but several others as well. we tried to run it last,first, and even not to run it at all
The GC Calculators and Method Translation Software (MTS) is available for download from Agilent.com . The package includes:
The Vapor Volume Calculator . It can be used to determine the expansion volume of a GC sample solvent at a given inlet temperature…
Hi, Here's a screenshot of the system suit, there is no blank subtraction The analyst said he has used the same processing method for a different run with no issues the only difference being that for those runs the MS setting was the same time as the…
The basic tools I would recommend to have for GC maintenance:
Ceramic column cutter
1/4" wrench (column nuts)
7/16" wrench (gas fittings at back of GC)
1/2" wrench (replace gold seal on S/SL inlet)
Torx 20 driver (removing FID collector assembly…
Agilent GC 7890A, FID, Split Liner. I'm setting up the column to do Hexane injection testing. It was set up this way previously but the program had been deleted and the column removed before I started here. Front Detector/Column which is below baseline…
Hello and Help!
My GC-FID's inlet pressure stays at 0.7 psi and does not reach the setpoint of 10 psi. Makeup gas reaches the 25 psi setting. Liner and septa are fine. I unscrewed the inlet column nut and placed my finger at the bottom of the inlet…
When you say that there are no signs of a leak, have you run a pump leak rate test using Agilent Lab Advisor? If not, I would suggest testing this. If you're unlucky enough for your peak to elute just at the point when the outlet ball valve fails to close…
Hello,
My laboratory runs a multilevel calibration with internal standards on a headspace-GC-FID. Our sequence is set up to replace each level of the curve after each calibrator is analyzed and then calculate the concentration of the analyte with the…
