APPENDIX A - RECOMMENDED PIPING
It is recommended that proper sample conditioning and flow control be maintained to obtain
representative samples. The Electric Power Research Institute (EPRI) guidelines for
representative sampling recommend maintaining constant and continuous sample flow in
sample lines. In addition, it is recommended that the sample be cooled to a temperature of 77
°F (25 °C) prior to analysis. (Note: Some analyzers may recommend a different sample
temperature be used to accelerate the analysis process.) Appropriate sample coolers or
heaters may be required. Consult the pressure and temperature specifications for your specific
analyzer and sampling system. Figure A1 shows the recommended sample conditioning piping
and instrumentation diagram (P&ID) when switching streams with the Sample Sequencer.
