6.11    Arithmetic Operation between Spectra   
 
Shown here is an example of obtaining the difference between 
two overlaid spectra.     
Display the spectrum for arithmetic operation.    Now, click the 
Arithmetic (A) command on the Data (D) menu or click the 
(spectral calculation) on the Processing toolbar.    A window as in 
Fig. 6-19 will open.

6.12  Area Calculation  
 
An area value is obtainable by integration in the specified range 
of the presently displayed spectrum.     
Select the Integration (I) command from the Data (D) menu or 
click the          (area calculation) button on the Processing toolbar.   
The window as in Fig. 6-22 will appear.

The principle of calculation is shown below.   
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Fig.6-25 
 
 
The elements (D
1 to Dn) of a spectrum are subjected to the 
following calculation for obtaining the area value.     
 
S3 =  {D
2 + D3 + … Dn-2 + Dn-1 + D1 + Dn}/2∗∆λ 
S2 =  (D
1 + Dn) ∗ {∆λ∗ (n-1)} 
(D
1 + Dn) ∗ (Section start wavelength (WL1)) –   
(Section end wavelength (WL
2)) 
S1 = S3 – S2
