a measure of the variation in the detector’s output signal when a sample component is not being detected. This can be classified into two types:  Short-term noise includes all observable random variations of the signal from the detector or other components having a frequency of about one or more cycles per minute.  Drift is the average slope of the baseline signal measured over an extended time period, for example, one-half hour
