we're doing GC-pyrolysis on a MAT-253 for H2 isotope analysis. However, our 
chromatography looks a little odd in a sense that the mass 3 trace tails behind 
the mass 2 trace of the chromatography peaks and the mass 2 ad 3 apeces 
do not always match: an inverse time-shift so-to-speak. Any word of wisdom 
on how to handle this problem?
