Create three additional
retentionwindows
calledTotal MonoGlyc-
erides, Total DiGlyc-
erides, andTotal
Triglycerides. These
windows should be
wider than the
monoolien, diolien and
triolien and should over-
lap the individual cali-
bration compounds.
The function of theTo-
tal Mono, Di andTri
windowswill be to sum
up all themono, di and
tri glycerides to arrive at
an answer for total
bound glycerin.
Enter the peak number for tricaprin sincewe
are still using tricaprin as the internal stan-
dard for theTotal windows.
Select the radio button labeledShow total of
all peaks.
Enter the factor specified in theASTM 6584
method. Monoglycerides=.2591
Diglycerides=.1488Triglycerides=.1044
This factor accounts for the percentage of the
moleculewhich is bound glycerin.
