TOTAL COMBUSTIBLES     n/a                         627    PPM

Estimated TCG          n/a                         0.555  %

ANALYSIS: Carbon monoxide level is above the accepted limit. Gas ratios
indicate no fault is present.

RECOMMENDATION: Resample in 6 months.

*In-Service Norms as follows
Generating            Transmission
H2     240  ppm               100 ppm
CH4    160  ppm               120 ppm
C2H2    11  ppm                35 ppm
C2H4   190  ppm                30 ppm
C2H6   115  ppm                65 ppm
CO     580  ppm               350 ppm
The above analyses were performed using the TOGAS direct injection system
rather than the vacuum extraction method described in ASTM D3612.
