I am having some trouble calculating the Response Factor when viewing my data. I am utilizing the ChemStation Edition with a 7890A GC. Based on the results of my calibration table, my Response Factor is coming out as 1 for all samples. I was also having some trouble creating a column that calculates Concentration %(wt/wt). It appears the Concentration %(wt/wt) was originally set to equal the "Compound_Amount," so it was simply giving me the concentration in [ng/ul]. If anyone could help with my data analysis trouble, it would be much appreciated!
