Problems solved by technology

Also sometimes burns out the ICP torch
[0007] (2) After the oil enters the ICP, the free carbon produced by decomposition at high temperature is easy to form carbon particles and deposit on the nozzle, which affects the stable operation of the plasma and the measurement of the spectrum
[0009] (4) The viscosity and physical properties of various organic solvents and oil samples vary greatly, which increases the workload for sample processing
[0010] (5) It is difficult to prepare standard samples. Generally, corresponding organometallic compounds should be used to prepare standard sample solutions.
However, organometallic compounds cannot be conveniently prepared and obtained
Commercially available organic standard samples are rare and expensive

Embodiment Construction

[0019] The preferred embodiments of the present invention will be described in detail below.

[0020] The present invention will be described in detail below by using an ICP spectrometer to detect and analyze the content of elements in lubricating oil. First, dilute the lubricating oil with an organic solution. The organic solution can be light diesel oil, xylene or MIBK. These three organic solvents can dissolve the lubricating oil and have good storage stability. However, considering the safety of the diluent, We choose light diesel oil as diluent. After the lubricating oil has been diluted, inject the diluted lubricating oil into the inner quartz tube of the torch of the ICP spectrometer. At the same time, a cooling gas is passed through the outer quartz tube of the torch. Oxygen is passed through the quartz tube in the middle layer of the tube, and the flow rate of oxygen is 0.3L / min.

[0021] Using the above scheme, the cooling gas is introduced into the outer quartz tu...

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...
