good day!
tell my please..
I have the air generator and his out pressure consist 52 psi, and and air consumption is 1000 ml/min. the EPC module GC 7890b work in rang 55-80psi. I have 2 detector FID. Tell my - with this generatorom may be worked ?…
yes, it's the purged 2-way splitter. Bottom is column entry, then detector 1 is FID, detector 2 is qtof. (switching FID and qtof position doesn't change anything)
We had 3.7mx0.15mm to qtof and 1mx0.15mm to FID with constant flow 0.8 ml/min for a 1…
Hi all,
I'm using a 0.18 mm HP-5 GC Column on a Shimadzu GC-2014 connected with a FID. I'm looking to get new ferrules (the old ones had been passed down from previous users) and wanted to discuss some options. I tried using some 0.5 mm graphite ferrules…
Thanks Marty, I was afraid of that.
Too bad really since piecewise is the most conventional kind of multi-level calibration.
I train using the example of a typical pH meter where they still naturally calibrate at pH 4, 7, & 10. Therefore there…
You can swap out cylinders to do it, but that means a lot more tubing, etc. to purge when you want to run. With the EPC unit, you would simply load the appropriate method to use it and the switch is done at the instrument. Much less tubing to purge and…
Hello,
To calculate the RSD and Pass/Fail results, one can try the following:
In the reporting go to the edtor and open "table properties"
In my specific case, I want to calculate RSD for Area, so I choose the column A, pA*s and press "Column…
Hi everyone, My MP-AES 4210 Machine sa is failing to suck/take-up the samples from the sample tubes..
I tried changing the sample pipes but nothing worked. Kindly asking for help on how to sort out this problem?
