GPMnGallons/1000 standard cubic feet of component n.
CONCNnNormalized (if selected) concentration of component n.
LCFnLiquid equivalent conversion factor for component n at 14.73 PSIA and 60
degrees F.
BASE PRS Base (contact) Pressure specified; defaults to 14.73.
DRYBTU/CF Uncorrected dry BTU content per cubic foot of total gas sample.
CONCNnNormalized (if selected) concentration of component n, calculated
from peak analysis.
BTU/CFnEnergy content per cubic foot of component n, stored in permanent
memory.
PTotal number of components to be used in calculation of total BTU/
CF.
100 Removed the 100 factored into the calculation of the concentration
earlier in the analysis.
