Product Introduction

Brief introduction

Different devices and components have different elements, so the location of wear can be determined through element analysis. For example, the piston is composed of iron and selenium. The piston ring is composed of chromium and iron. If the content of iron element increases from 30ppm to 150ppm, the wear and tear of the equipment will definitely intensify. If there is also an increase in selenium content, the location of wear can be determined.

Spee over 120MOil spectrometerThe number of detectable elements is 15, mainly used for the detection of air force special oil. It adopts rotating disk electrode technology and has the advantages of small size and high detection accuracy.

IISpike Chao120MOil spectrometerWorking principle

The use of atomic emission spectroscopy is the same as all other atomic emission spectroscopy, consisting of an excitation source that provides energy, an injection system, an optical system for spectroscopy, and a detection system for signal detection.

The 120M is specifically designed for in use oil testing, with the main difference beingexcitation sourceThe function of the excitation source is to provide energy for the evaporation, dissociation, and excitation of the sample. The excitation source will excite the elements in the sample, dissociate them into other atoms, and then cause the gaseous atoms to emit a characteristic spectral line. Spaco Superoil is specifically developed for lubricating oil. The excitation source of Speechao is based on the oscillation type circuit discharge defined by the US military JOAP, which includes preheating, low-frequency firing, and high-frequency firing, and optimizes the most suitable excitation temperature and evaporation temperature. This special excitation source also has good sensitivity and stability to low content elements.

Sample injection systemWhen using a rotating disk electrode for injection, one-third of the rod electrode is immersed in the oil box during detection. The disk electrode begins to rotate, bringing the oil sample into the gap between the disk electrode and the rod electrode, and is excited by the excitation source.

The light will be affectedoptical systemCapture it and then perform spectral analysis. Oil samples will not enter the optical and detection systems, so no matter what particles or substances the oil contains, they will not damage the optical system.

Analysis systemIt is a 15 piece CCD that can ensure the sensitivity of pixel height. The optical system maintains a constant temperature of 40 degrees Celsius and has functions such as automatic peak searching, dynamic background compensation, standard curve, and quantitative algorithm. Its main purpose is to eliminate the influence of the matrix (oil composition) on the detection results, eliminate the influence of environmental light or combustion process light on the results, eliminate the influence of spectral line overlap between different elements, eliminate the influence of oil sample viscosity, eliminate the differences in sample addition, sample volume, and porosity among operators.
