Abstract

The invention discloses a method for detecting the content of elements in oil with an inductively coupled plasma (ICP) spectrometer. The ICP spectrometer comprises a torque tube, and the torque tube is formed by three layers of concentric quartz tubes. Cooling gas is guided into the quartz tube of the outer layer, oxygen is guided into the quartz tube of the middle layer and gasoloid of the oil which is diluted by organic solution is injected into the quartz tube of the outer layer. The method for detecting the content of elements in oil with the ICP spectrometer makes up the deficiency of the prior art.

Description

technical field

[0001] The invention relates to a method for detecting element content in oil, in particular to a method for detecting element content in oil by using an ICP spectrometer. Background technique

[0002] Lubricants are widely used in machinery manufacturing, transportation, petroleum industry and many other fields. The content of additive elements in lubricating oil is usually an important indicator of lubricating oil quality and performance. At present, the most widely used methods for detecting lubricating oil are atomic emission spectrometry, atomic absorption spectrometry and X-ray fluorescence spectrometry. The processing methods of lubricating oil are generally dry ashing, wet digestion, microwave digestion, emulsification technology and extraction. Processes such as separations process samples into aqueous solutions, and there is also a faster organic direct injection method.

[0003] The dry ashing method generally involves carbonizing the sample at h...
