For the detection of triphenylphosphine, high-performance liquid chromatography (HPLC) can be used. The specific steps are as follows:

Sample preparation: Dissolve the sample in a suitable solvent at a specific ratio to achieve an appropriate concentration.

Chromatographic condition setting: Select a suitable column and mobile phase, and set appropriate flow rate and temperature.

Sample injection: Inject the sample into the chromatographic column and detect it using a suitable detector.

Data processing: Analyze and process the detection results using data processing software to determine the content of triphenylphosphine in the sample.
