The experimental methods are those commonly used: Nuclear Magnetic
Resonance (Minispec (20 MHz) from Brücker S.A), specially calibrated
for water to get stable signal around 9000 microsec for the 90° pulse
and twice that value for the 180° one.
Liquid Scintillation (Tricarb 2300 from Packard S.A), Computers on a
Local area Network (Hewlett Packard 850 MHz, Power Macintosh 400 MHz).
The dilutions-succussions are performed according to the classical principles,
the succussion machine allowing to remake exactly the same energy in
every given diluted-succussed solution.
The water used presented a minimum of relaxation time T2 equal to 2100
millisec to get the required high purity, and therefore comparable data.
Finally, various conventional equipment are also used: ultrasonic devices,
magnetic field generators, incubators, freezers, automatic pipettes,
and so on ....
