I am wondering if anybody of you has experience with the shielding of magnetic fields.
The situation here is that with our new IRMS being installed at appr. 2.30 m distance from the old one we get magnetic interferences between the two instruments, e.g. the stability is not as good as before, especially when the other instrument is doing a magnet cycle or is changing from CO2 to N2 configuration. The company was quite surprised that this happens at this distance, but unfortunately we do not have more space to move the two instruments further from each other.
So the idea was to probably use some shielding equipment - there are quite some foils and plates for shilding of magnetic AC fields on the market (e.g. http://www.magnetic-shield.com/index.html). However the prices for this are not exactly low so that we would like to know beforehand if anyone was encountering the same problems and was able to solve it with such shielding.
All other ideas or recommendations are also very welcome - by the way, it does not really help to use one magnet field setting for CO2 and N2 and change the accelarator voltage accordingly; though this would keep magnetic fields constant for all measurements, it has a bad effect on linearity... :-(
