Determination of organic phosphorus impurities in liquid crystal materials by FPD gas chromatography
A FPD-GC method for determination of organic phosphorus impurities in liquid crystal material was established. The method with good reproducibility can be applied to simultaneous determination of triphenylphosphine and triphenylphosphine oxide. The relative standard deviations (RSD
n
=5) of triphenylphosphine oxide and triphenylphosphine were 4.4% and 5.6%. The recoveries ranged from 80% to 110%. The experiment has a good guiding significance to the establishment of the analytical method in the process of industrialization.
