12) Press Enter to view the average of the blank replicates, which establishes the
reference for the test, then press it again to continue.
13) Remove the blank bottle and insert the requested sucrose standard vial. Press Enter
and its contents are sampled and analyzed. The sucrose replicates are displayed once
all analyses have been completed. Press
Enter to view the average of the sucrose
replicates.
14) Press Enter and then remove the sucrose standard and install the 1,4-benzoquinone
standard.
15) Press Enter to sample, analyze and then average the 1,4-benzoquinone standard.
The 1,4-benzoquinone replicates are displayed once all analyses have been
completed. Press
Enter to view the average of the 1,4-benzoquinone replicates.
16) Press Enter and the results of the system suitability test are reported:
The instrument passes the system suitability test if the response efficiency is no less
than 85% and no more than 115% of the limit response for the sucrose standard.
Rep #1 = xxx ppb
Rep #2 = xxx ppb
Rep #3 = xxx ppb
Press Enter

is the average TOC response for the sucrose standard C.
r
ss
is the average TOC response for the 1,4-benzoquinone
system suitability standard.
r

is the average TOC response for the reagent blank.
LR is the limit response of the instrument.
R

is the TOC response efficiency of the Analyzer which is
calculated by the formula:
