#Base line is nothing but the detectors response to the
mobile phase.(gc,hplc)

#Base line should be stable to start a run.

#Un stabilized base line is called as base line noise.

#Base line noise is of many types..
1)Cyclic base line
2)Synchorinise noise
3)Asynchorinise noise
4)Base line drift
5)Spikes
6)Negative peaks
7)No peaks

#Base line noise is attributed due to mobile phase,sample,
system problems.leaks in the system,temperature variations
in lab etc..
