• Bottle positions graphics
• Unlock icon energizes the bottle bay door lock for five seconds, allowing you to
open the door.
• Back icon takes you to the run standards dialog box.
• Forward icon takes you to the review test options dialog box.
• Cancel icon returns you to the run standards dialog box. All changes made in any

Close the bottle bay door.
Touch the forward icon. If bottles have been properly loaded and the RFID tags can
be read, the review test setup dialog box appears. See
Otherwise, the enter bottle information dialog box appears. See
page 81.
When the test running dialog box appears, the analyzer begins running the test.
• Three samples are drawn from each bottle. After all the repetitions are complete,
the analyzer repeats the process for the rest of the bottles. All reported values must
be normalized to 500 ppb using the following formula.
• Once all the bottles have been analyzed, the analyzer compares the average
reading of the sucrose standard to the average reading of the 1,4 benzoquinone. If
the two values are within ±15% of each other, the test passes. The analyzer then
displays the test summary dialog box. The following formulas are used to calculate
the response efficiency.
Where:
SR = Suitability response of the analyzer defined as (r
LR = Limit response of the analyzer defined as (r
re = Response efficiency of PAT700.
r = Average TOC response for the blank.
w
r = Average TOC response for the sucrose standard.
s
r = Average TOC response for the benzoquinone standard.

When the suitability test is completed, the test summary dialog box appears, with
the results of the test and a notification of whether the test failed or passed. The
results also appear on the printout if a printer is attached. See
Touching the forward icon takes you to the run again dialog box
page 85). If the test failed or you have rejected the test results, at the run again
dialog box, touch the checkmark icon to run the test again or the cancel icon to
cancel the run.
