I prepared 5, 10, 50, 100 PPM standard from pure ethylene glycol ran it on GC-FID. When i went and did quantification of calibration. The concentrations are not right. Something weird is going on in the software. Can anybody help please. For 5ppm it is giving 17ug/L. For 10PPM it is giving 9.5 ug/L. For 50 PPM it is giving 17ug/L for 100 PPM it is giving 115ug/L. I tried everything i don't know what am i doing wrong. Can anybody help me in this situation. Thanks
