| Abstract: | Oils containing 0~100 ppm biphenyl and phenyl ether were analyzed by a new gas chromatographic method. Correlation coefficients
(r) between gas chromatographic peak heights and biphenyl and phenyl ether concentrations were 0.99 and 0.98, respectively.
As little as 5 ppm biphenyl and phenyl ether in oils could be determined rapidly and efficiently in 90 min by this new method. |
