Calling people stubborn asses doesn't help yours either.

It does depend on what your are trying to detect. It's certainly true in 
a lot of situations of practical interest. Laboratory NMR machines did 
go in for high magnetic fields.

That does depend on " highly sensitive magnetic sensors - SQUIDs, 
magnetoresistive sensors, and SERF atomic magnetometers".

Super-conducting quantum interference devices used to need liquid 
helium. Presumably high temperature super conductors could let you get 
away with liquid nitrogen, which is lot cheaper.

I was a chemist for long enough to be aware of the difference between 
faddish research technique that you only found in research labs and more 
  practical approaches that you run into in industry.

Since I spent quite a few years working on electron-beam 
microfabricators which sold for about a million dollars into 
semiconductor fabs that cost about $500 million dollars (back then) my 
idea of "industry" covers some fairly high end gear.
