7.12  Area Calculation 
 
An area value is obtainable by integration in the specified range of the 
presently displayed spectrum. 
Click the 
  (area calculation) button on the Processing toolbar.     
A window as in Fig. 7-32 will appear. 
(Or select the Area command from the Data menu.) 
 
 
 
Fig. 7-32 
 
 
The range for area calculation is settable in the following two ways. 
 
(1)  Setting by Moving Cursor 
 
① Click the Start button.  (Refer to ① in Fig. 7-33.)   
Move the trace cursor to a desired start wavelength on the 
spectrum (refer to ②  in Fig. 7-33), and then click the right 
button of the mouse. 
 
② Click the End button.  (Refer to ③ in Fig. 7-33.)  Move the 
trace cursor to a desired end wavelength on the spectrum 
(refer to ④  in Fig. 7-33), and then click the right mouse 
button.

(3)  The principle of area calculation is shown below. 
 
 
 
 
Fig. 7-34    Principle of Calculation 
 
 
The elements (D
1 to Dn) of a spectrum are subjected to the 
following calculation for obtaining an area value. 
 
S
3 = S1 + S2 = Sa + Sc + Sd 
= {D
2 + D3 + 


 Dn-2 + Dn-1 + (D1 + Dn)/2∗∆λ 
S
2 = Sb + Sd 
= [(D
1 + Dn)∗{∆λ∗ (n – 1)}]/2 
= [(D
1 + Dn)∗{section start wavelength (WL1) –   
section end wavelength (WL
2)}]/2 
S
1 = S3 – S2 
D
1:    Spectral data at section start wavelength 
D
n:    Spectral data at section end wavelength 
∆λ:  Sampling interval 
 
In the time scan mode, change as follows. 
Start wavelength (WL
1) → End time (T2) 
End wavelength (WL
2) → Start time (T1)

The result of area calculation can be printed out. 
 
(1)  To print a spectrum and the result of area calculation, put a check 
mark at “Print spectrum.”    (Refer to ① in Fig. 7-35.)  To avoid 
printing a spectrum, remove the check mark. 
 
(2) Click Print to start printing.    (Refer to ② in Fig. 7-35.)   
Upon execution of printing, the Area window will close.     
The same window can be called up by clicking the 
 (area 
calculation) button on the Processing toolbar.

(3)  Upon clicking the OK button after calculation (refer to ③ in Fig. 
7-35), its result is saved although the Area window is closed. 
 
(4)  The result of calculation is reset by clicking the 
 (reset) 
button on the Processing toolbar with the data processing window 
displayed.    Upon calling up the Area window again, therefore, 
“*****” will be indicated in each result box. 
 
NOTE:  Upon execution of file saving after area calculation, its result is 
also saved in a file.    So a numerical value is indicated in each 
result box when the Area window is called up.    These values 
cannot be erased by clicking the reset button because they are 
saved in the computer.

For expanding the scale in the Area window, use the left button of the 
mouse. 
 
(1)  As shown in Fig. 7-37, specify an area to be expanded by drawing 
a rectangle with the mouse while holding down its left button on a 
spectrum. 
 
 
 
Fig. 7-37 
 
 
(2)  Then release the left button.    The specified area will be 
expanded as shown in Fig. 7-38.

(3)  Double clicking the left mouse button on the spectrum returns the 
scale to the original one.

7.13    Transfer of Data to Microsoft(R) Excel 
 
Measured data can be transferred to a worksheet of Microsoft(R) Excel 
in the following procedure. 
 
(1) Click the 
  (properties) button and select the Report tab.     
A tab page as in Fig. 7-39 will open.    Select “Use Microsoft(R) 
Excel” for Output.    Also select data to be transferred (peak table, 
data listing, etc. in case of wavelength scan).    Then click OK.

(2) Click the 
  (report) button.    The Microsoft(R) Excel will 
automatically start to read data.    The subsequent procedure 
concerns the Microsoft(R) Excel operation.

(4)  Upon closing the Microsoft(R) Excel, a window as in Fig. 7-42 
appears.    Now close this window.    The original data processing 
window will appear again.

7.14    Pasting of Spectrum to Microsoft(R) Word 
 
A spectrum can be pasted to a Microsoft(R) Word text as it is.     
Take the following procedure. 
 
(1)  Make spectral data active by clicking the relevant spectrum in the 
data processing window.    The thick frame will change to blue. 
 
(2)  Select the Copy command from the Edit menu. 
 
(3)  Open a Microsoft(R) Word text and click a position for pasting.     
By clicking the Paste command from the Edit menu, the spectrum 
can be pasted to the Microsoft(R) Word text. 
 
Peak tables and/or kinetics data can also be pasted to a Microsoft(R) 
Word text in the same way.    In this case, they are pasted as a text. 
By double-clicking the pasted spectrum, functions such as scale change 
and gridline indication are applicable.

Upon right-clicking the pasted spectrum, a menu box as in Fig. 7-48 will 
appear to enable scale change, etc.    Any change made here is brought 
into a Microsoft(R) Word text. 
 
NOTE:  Editing in the Microsoft(R) Word can be made with a PC in 
which the Microsoft(R) Word and FL Solutions program are 
installed.
