(a)  Compounds detected on Tenax&reg for which Entropy has obtained quantitative 
     reference spectra.  Blank spaces indicate a non-detect.
(b)  Probably a mixture of alkane hydrocarbons which may include hexane together
     give absorbances similar to hexane.
(c)  Concentration of detected compound in FTIR cell calculated using MCOMP
     analytical routine.
(d)  Concentration of detected compound in flue gas calculated by dividing 
     in-cell concentration by the concentration factor (see Section 4.6.5).
