- extremely
powerful, low pass noise filter
- compatible
with any HPLC detector
The LINK is an active, fourth order (four-pole) noise filter to
improve detection in liquid chromatography. It has been developed
as a stand-alone unit and is applicable with any detector that supplies
an analogue signal.
The improvement in Signal-to-Noise ratio depends on the frequency of the signal
vs. the noise. In a realistic experimental set-up consisting of an
optimised LC-EC system for biogenic amines, up to a factor of 600
improvement in detection limit has been obtained.
Cut-off frequencies of 0.300, 0.171, 0.120, 0.086, 0.067, 0.055, 0.046,
0.040, 0.034, 0.030 and 0.020 Hz (11 settings) can be selected. The
attenuation slope is 24 db/oct (80 db/decade).
