Total Organic Carbon Analyzer Appendix
Teledyne Analytical Instruments 77
A.3.4 Option 200016
EXTERNAL RANGE CHANGE
This option provides for local or remote analyzer range change by
contact closure.
A.3.5 Option 200017
TRUE DUAL RANGE OPTION (not an electronic scaling)
A.3.6 Option 200009
MULTI-STREAM SEQUENCER
This option allows time sequencing of analysis of up to Four (4)
different streams.
A.3.7 Option 400008
DBPR OPTION
This option is configured to fully comply with the Disinfection
Byproducts Rule as defined by the USEPA. The analyzer is configured
for a two stream sequencer and displays source TOC, distribution TOC,
out-of-tolerance alarms, alkalinity input and pH input.
A.3.8 Option 200026
COD/BOD CORRELATIONS
Both COD and BOD readouts are correlated to “instantaneous”
TOC analyses. Thus, the operator is provided with useful, predictive,
real-time analogs derived from the actual organics in the sample. While
TOC provides the most specific measurement for process control for
organic loading/treatment, spill detection, etc., COD and BOD continue
to provide useful data, which is often required for permits. Regulatory
agencies will often allow substitution of TOC analysis for COD and
BOD if proper correlation is performed. The correlation requires
multiple testing for COD and/or BOD on the same sample taken at the
same time of TOC analysis and recording those results when available
later. This may take one sample per day for 30 days. After sample
characterization, COD and BOD readouts may then be used as
“instantaneous” control parameters.
