DATA ANALYSIS

In quantitation the data analysis examines the statistics 
of the standard curve and algorithm of the curve fit. The 
curve statistics function is accessed by pressing the key 
below  the 

S

  icon  in  the  quantitation  curve  menu.  The 

algorithm  of  the  curve  fit  can  be  changed  by  pressing 
the key below the 

curve fit 

icon. For more information 

regarding curve fit and statistics refer to section 8.2.3.
