I am confused on the concentration of eo in headspace. Require to have a calibration of 0.4,0.8,1.2,1.6,2mg/l eo in ethanol. Then prepare 0.5mg/l PO as internal std. If take 2.5ml volume of 0.4mg/l eo plus 2.5ml volume of 0.5mg/l PO. hence is it my calibration become half =0.2mg/l eo if base absolute weight. But curious part is I still able get back recovery eventhough I assume the concentration maintain as 0.4,0.8,1.2,1.6 &2mg/l.
Thanks
