Introduction
2.1
To compenstate or eliminate the effects of drift and disturbances to the magnet
sysem, a special regulating system has been employed. Every variation in the mag-
netic field brings about a change in the magnetic resonance signal.
To achieve the necessary high stability we employ a special measurement/regulation
system known as the LOCK CHANNEL. This requires an independent, complete
transmission/receiving channel for Deuterium that is used to stabilize the magnetic
field with a regulating system.
Deuterium is added to samples that we wish to measure. In most cases Deuterium
has no influence on the outcome of experiments conducted with the NMR system.
In special cases where Deuterium is the substance of interest an alternative lock
channel can be used. This alternative channel (option) uses Fluorine as the lock sub-
stance.
The Daedalus Lock is applied to ARX, AMX, DRX, DMX, DPX-Spectrometers.
