用因子分析法确定了在高效液相色谱分析测定载热油中联苯及联苯醚含量时,由于柱效严重降低而导致的不纯色谱峰中的吸光物种数,处理结果与采用良好色谱条件时结果相符。
Factor analysis was used to determine the number of light-absorbing species in the impure chromatographic peaks due to the serious decrease in the efficiency of HPLC when the contents of biphenyl and diphenyl ether in the heat-conducting oil were determined. The results were compared with those obtained by good chromatography Conditional results.
