3.10 Post Wash
Automatic post wash cycles are typically part of every measurement cycle. At the end of the
analysis, the post wash cycle evacuates the reacted sample from the cell and cleans it to
minimize coating and residue deposits in the cell. The post wash cycle settings can be accessed
from the ANALYSIS PARAMETERS menu:
MENU → SETUP → (+) ANALYSIS PARAMETERS →(+)
Please consult before modifying any of the parameters.
3.11 Priming
Priming of the instrument lines may be done as auto (all the solutions) or manually by selecting
the specific reagent or standard. Priming fills the tubing, purges the lines of air, and prepares the
analyzer for measurement mode.
The PRIME VOLUME in mL applies to all the listed solutions in the priming menu.
The Prime Volume may be specified as a (-) number; this allows the user to pump back the
reagents inside the tubing back into the reagents containers allowing for safer service when
replacement of the tubing is needed. User may select to pull back all or any one of the reagents
or standard.
