TIPS – GETTING THE MOST OUT OF YOUR SHIMS – AV500 AS AN EXAMPLE
The majority of lock solvents used in our facility are fully deuterated i.e. 99.0% or more 2H enriched. This means that the Topshim system performs what is called ‘1D gradient shimming’ or ‘Z-axis only’ shimming. This leaves the job half-done when it comes to shim optimization. The XY-plane or ‘transverse plane’ shims also need adjusting, […]

ALERT ! AV500 OK – WITH IMPORTANT CHANGE – PLEASE READ !
CURRENT STATUS : First I will highlight that the sporadic Topshim problem is gone now and the shimming is behaving as expected. That should come as a relief to all of you who exclusively use 2H lock solvents other than (H2O+D2O) or (CH3OH+D2O). IMPORTANT – PROBEHEAD CHANGED TO BBI In the process of system troubleshoot, […]
