2.5.2 Using the COD/TNT Vial Adapter
The methods for chemical oxygen demand (COD) and Test ‘N Tube
(TNT) procedures in the DR/2010 Procedures Manual use 16 mm vials as
the sample cell for the colorimetric measurement. Place the vials into the
COD/TNT Vial Adapter after it is installed in the cell compartment (see
Figure 5). This adapter also holds standard 16-mm test tubes.
Place the COD/TNT Vial Adapter in the instrument's sample cell
compartment with the orientation mark toward the left. The light shield
cap included with the adapter must be in place when measuring samples.
The cell compartment cover remains open.
