Explain What Is A Base Line?

Answer»
  • 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.. 
    • Cyclic base line 
    • Synchorinise noise 
    • Asynchorinise noise 
    • Base line drift 
    • Spikes 
    • Negative peaks 
    • No peaks
  • Base line noise is ATTRIBUTED due to mobile phase,sample, system problems.leaks in the system,temperature variations in LAB etc..
