What is the significance of detector noise during GC calibration

Hi p.balaji,

I have updated the tags on your post for better visibility. The measurement of detector noise during a qualification of an instrument is to ensure the detector is working within specification. The impact of a failure is really left up to the user of the instrument. Some customers will place the instrument out of service until the noise issue is addressed other customers , depending on the noise problem will continue use, its really your call. If this is a QC instrument, most often it is placed out of service.

Signal to noise is a measurement of response of a peak compared to an section of baseline or background.

The noise, wander, and drift are calculated according to the method described in ASTM standard E685-93.

James
