For the tests listed in Table 1 , an additional purge cycle of the Pour-Thru
Cell with deionized water is required between samples.
The Dual Path Length Pour-Thru Cell, 1 inch/1 cm can also be used for
the Nessler Method for nitrogen and TKN if cleaned correctly. For this,
pour a few sodium thiosulfate crystals into the cell to clean it. Rinse out
the crystals with deionized water.
The use of the Pour-Thru Cell is not possible for the tests listed in
Table 2 , since chemical problems or other complications can occur. Use
the sample cell specified in the procedural instructions for these tests.
