After each sample,inject H2O enough time to obtain a clean baseline (e.g. area counts for EG and DEG should be less than 20% of the areas observed from standard H )。 smaple Calculations -TO determine the combined levels of EG and DEG in the polymer sample, Multiply results from the GC report (RF*Area=ppm in solution)by 0.0003 to obtain wt% polymer.Add the values for EG and DEG to obtain the combined EG and DEG value. Note,in peakpro,this can be accomplished by using "factor 3"=3 and "Factor 4"=10000. |
