6. After all of the foam wash is removed, the reagent pump
starts, the wash bypass, and vent valves open, and the
remaining solid wash segment moves to the inner sample
port. After the solid wash segment reaches the inner
sample port, the reagent pump stops and the sample pump
empties the wash from the sample port area. The reagent
pump introduces another solid wash segment into the
sample port. When the CO-ox module is attached, wash
segments are split at the sample connector, so the CO-ox
sample path is thoroughly cleaned. This sequence repeats
11 times to create wash segments that thoroughly clean the
measurement module. The waste pump is on.

7. After the wash segments pass through the measurement
module, the Cal gas valve opens and the sample pump
starts to move Cal gas into the measurement module. The
CO-ox pump moves the remaining wash segments to the
waste bottle. The waste pump is on to prevent a bubble
from forming at the sample port. The sample door opens
when the sequence completes.
