Quick Noise Test
Quick Noise Test
The noise test measures the noise of the detector, with HPLC- grade water
flowing through the flow cell at 1 mL/min, in one minute intervals over a
total of 5 min.
The noise of the detector is calculated by using the maximum amplitude
for all random variations of the detector signal of frequencies greater than
one cycle per hour. The noise is determined for 5 one minute intervals
and is based on the accumulated peak- to- peak noise for the intervals. At
least seven data points per cycles are used in the calculation.
The cycles in the noise determination are not overlapping.
In order to obtain reliable results, the lamp should be turned on for at
least 10 min prior to measurement.
