Phosphorane detection and absorption device

The utility model belongs to the field of metal detection of phosphorane, and provides a phosphorane detection and absorption device which is characterized in that a phosphorane pressure reducing valve is connected with a flow meter through a ball valve I; the nitrogen pressure reducing valve is connected with a flow meter through a ball valve II; the flow meter is connected with the suck-back prevention bottle I through a pipeline; the suck-back prevention bottle is connected with the gas washing bottle through a pipeline; the gas washing bottle is connected with the absorption bottle through a pipeline; the absorption bottle is connected with a tail gas absorption device through a pipeline. The method comprises the following steps: diluting a sample by a proper multiple by using an ICP-MS (Inductively Coupled Plasma Mass Spectrometry) analytical instrument, injecting the diluted sample into inductively coupled plasma, ionizing metal elements, separating ions by using a mass spectrometer according to a mass-
