4.Sample analysis
Before proceeding to analysis clean the cell with distilled water. Wipe the cell with a cellulose paper to remove
drops of water and fingerprints.

4.1 Basic mode

To determine the absorbance or transmittance of different samples at a certain wavelength:
Put the cell with the blank reference into the cell holder and place it into the light path.
Select Basic with F1 (2.5). The equipment will make the blank automatically and then will enter the measuring
mode display (Fig. 11).
Figure 11
On the upper part, the selected wavelength (WL) and 100% T or 0.0000 Abs depending on the working measuring
mode will be displayed. Immediately below a chart headline will appear:
No.
Number assigned in
order to each result
The results of the successive analysis will be shown on this chart.
Put the cell with solution to be analyzed into the light path. Select Test with F1 (2.5); the result of the measure-
ment will be displayed
Figure 12
Repeat this process with the different samples. The spectrophotometer can save up to 200 data.
To return to the main menu select Cancel with F2 (2.6).
Note: At the basic mode, the wavelength can be adjusted and the blank can be made as many times as needed by
λ
pressing GOTO (2.1) and ZERO (2.2) respectively.
