Rather than tailoring the method conditions to the new compounds, information on each NTGA was simply added to the spectral library and the samples were analysed using the method conditions listed in ASTM D [21].

    However, once the compound is in the library, it can be analysed and quantified using GC-VUV as described in this paper. Molecules eluting from the GC are exposed to light in the VUV range nmand because nearly every compound absorbs strongly in this range, compounds can be identified by their unique spectral fingerprints and quantified according to Beer-Lambert Law principles.

    International Journal of Modern Organic Chemistry 2 3 While NTGAs may coelute with other compounds in gasoline, spectral deconvolution allows them to be identified and quantified without issue. For example, one study determined that ethyl acetate may be used as a beneficial octane-boosting compound that provides desirable properties, such as increased water tolerance [1].

A recently developed technique, gas chromatography - vacuum ultraviolet spectroscopy GC-VUVhas proven to be a powerful alternative to traditional methods of gasoline analysis. SOP No. However, it contains less energy per gallon than gasoline [11], and the increased requirements for crops such as corn would drive up food prices [12], so using too much ethanol in gasoline is not desirable.
