98 of 220 Calibration and Validation - Anatel A643a
RPS - June 2007 - Edition 12
Operator Manual Anatel
Because the sucrose and 1,4-benzoquinone standards cannot be made to exactly 500 ppb,
the reported sucrose and 1,4-benzoquinone responses are corrected with the Certificate of
Analysis values as follows:
17) Press Enter to save the test results and initiate a printout of the data. If the limit
response exceeds the current TOC alarm limit, adjust the instrument’s Alarm Limit to
the calculated limit response. Press the appropriate key to continue.
18) Once the system suitability procedure is complete, remove the standard vial and
reinstall the sample vessel before proceeding.
A printout or display of this system suitability information also is available through the Data
History Menu selection (see “Data History” on page 99).
In the event of instrument failure, the sample discharge may contain 1,4-benzoquinone, which
is a hazardous substance (refer to “Material Data Safety Sheets” on page 205).
