Hi.i have shimadzu qp 2010.i want analyze high alcahol,methanol, aldehyds and esters in vodka by gc.i havent mix standart.i have seperately 9 standarts.i want prepare each standart 3 concentration.how can i build calibration curve?methyl acetat 3ppm,5ppm,9ppm
Ethyl acetat 3ppm,5ppm,9ppm
Acetaldehyde 3ppm,5ppm,9ppm
Propanol 2 3ppm,5ppm,9 ppm

How can i build this standarts and concentrations in one curve?

At least initially you need three calibration plots: one for each compound. From those you can determine the relative responses of the analytes. Once you have that, you can do a single calibration plot for one of the analytes and apply the appropriate response factors for the other two.

İ cant understand can you explain simple way?

Nobody can understand why 3 calibration plots for 4 compounds - just loughing
