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
minutes.
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
minutes prior to measurement.
