WASH IN PROCESS indicates that the analyzer started a new
sample analysis cycle, the analysis cycle starts with a wash
sequence which is designed to first flush and clean the
analyzer reaction cell and then to capture a fresh sample for
executing the measurement steps of the analysis.
2210AM Analyzer ONLY
The UNIVERSAL 2210AM Ammonia analyzer has a specific
programmed method for executing the wash and sample
capture; the method starts with a PRE-WASH sequence. The
FIRST step in the sequence allows for evacuating the reaction
cell and allows for hold time or stir time (default to 1 sec), this
delay or stir time is user programmable and can be adjusted
to provide the sample conditioner additional time to acquire,
condition and feed a fresh sample to the analyzer from the
process.

conditioner to collect and feed a new sample to the analyzer.
