8.2.1 Reaction Time
REACTION TIME 6m09s ▪ REACTION TIME displays the total reaction time (in minutes and
seconds) for range 1, based on all programmed settings in
System Program, System Program 1 menu.
INTERVAL 0m
▪
INTERVAL is the time (0 minutes by default) added between
each reaction. Interval can be programmed on site if frequent
analysis is not necessary. The longest interval time, which can
be programmed, is 1440 minutes (or 1 day). A programmed
interval time would reduce the reagent usage significantly.
▪
When BioTector automatically extends the reaction time due to
high level of TIC and/or TOC in the sample, if any INTERVAL
time is programmed, the extended reaction time is taken out
from the interval time.
▪ BioTector automatically generates an INTERVAL time when the
user programs any SAMPLER, FORWARD and/or REVERSE
times, which exceeds the maximum allowable time in the
Sample Pump menu below. The system determines the
maximum allowable time from the System Program 1 settings in
System Program menu.
TOTAL 6m09s ▪ TOTAL displays the total reaction time including the interval time
if programmed.
