A new determination method of natrium in naphtha by ethane-air flame atomic emission spectrometry was studied. The influence of ionization interference in the determination was inhibited.
Acrylic resin is diluted in ethyl acetate and the remnant monomer is well separated from it by gas chromatography and is quantificationally measured by hydrogen flameionization detector (FID).
As to GC with a workstation, this paper introduced a new method used to evaluate the uncertainty of calibration for detection limit by flameionization detector.
