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…
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…
Hope your week is going well, can wait for spring to actually arrive.
When we turn auto offset on for either of our GCs, it ramps the output so high that it shuts down. This is just for the nitrogen phosphorus detector. We normally turn it off, but…

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…
Hi there! We have a Cary 60. We are doing preventive maintenance, but the noise test fails and it took up to three or four times to get a successful result. What can we do to improve this and get a passed result the first time?
We have several 1220 Infinity II system (G4290B) on our location. They are connected same type of computers with same windows. Only one of them has connection issue as below. Since there is connection to detector (I can control detector fully), I am not…
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…
