Use the optional Pour-Thru Cell (Cat. No. 59404-00) with the Multi-pathlength
Cell Adapter (Cat. No. 59466-00) to save time when analyzing the same
parameter in many samples. Because the same optical characteristics exist for
both zeroing and measuring, or when comparing measurements of different
samples, any error that would have resulted from optical differences between
individual sample cells is eliminated. Rapid Liquid methods speed analysis and
require use of the Pour-Thru Cell (see the
Procedure Manual for these programs).
When using the Pour-thru Cell, keep the instrument lid open. The light cover on
the cell will ensure accurate readings. See the instructions for the Pour-thru Cell
for more information. Use at least 25 mL of sample to completely flush the cell.
2.9 Assembling the Pour-Thru Cell
The Pour-Thru Cell Assembly (Cat. No. 59404-00) must be assembled and
installed before use.
