Also you can use a xtal oscillator and put the sample in one face (nude xtal). This is similar to technic used in microbalance detector for molecule of explosives and others.

Just curious; what exactly is going on "In this chamber is a coil (1,000 tuns fine wire) wich "noses" the molecules of bill" ?

I'm not familiar with your term "noses". Could you liken this term to a known physical scientific process, either chemical, mechanical or perhaps electrostatic?
