What was the EM Voltage before the source cleaning and filament replacement? How old is the electron multiplier? They do not typically fail, the tune EMV setting slowly gets higher and higher. They typically work fine up to ~2500V or so and then the gain…
Hi mubashirraza, PCBs are not commonly sampled via headspace. SPE is more commonly used as a cleanup step followed by standard auto-sampler injection. PCBs are more often detected using MS or uECD due to their more selective operation. I've attached some…
Hello! I realize this is an old post but wanted to provide more details in case other users encounter the "Make directory failed" error in the future.
This is captured in Software Status Bulletins (SSB's) in a few places.
The solution, if you encounter…
Hi emilymorin ,
I'm glad you found a solution that works for your data sets. I have continued to investigate this issue, but your solution does not work for all of the data sets I have tested with. I suspect disabling the save file feature may work…
Yes, the peaks are changed at every time in response, and may be a little shifted in retention time, but Ii tried to make autotune , but it failed , so Any suggestions
As per my knowledge after changing any component in GC (FID assembly,Injector liner parts,Column) the instrument need to be kept for conditioning about minimum of one hour other wise as you did three to four blank injections has to run. Due to the temperature…
Hello, I am having troubles with the MS40+ pump I use for my ICP-MS machine. I did an oil change yesterday and cleaned out the inside as well as the filters (the oil was pretty low since I had forgotten to check it for a while) and now when I go to turn…
