- 中文摘要:
Isobutanol in phosphoric acid was detected by gas chromatography with a flame ionization detector. Samples with high content (>100μg/ml) of isobutanol were diluted with a n-pentanol aqueous solution and the diluted solutions were directly injected into the GC column for the determination of isobutanol. For lower content samples, isobutanol was preconcentrated by vacuum distillation or CCl4 extraction followed by activated alumina adsorption. In whole GC measurements, n-pentanol was used as an internal standard.
The flame ionization detector is capable of detecting quantities of isobutanol as small as 5×10¯8g. with preconcentration, isobutanol at the concentration of 0.4μg/ml or lower can be determined. - 英文摘要: --
