Description

A method for positioning analysis in glow analysis

technical field

The invention belongs to the technical field of glow spectrum analysis, and particularly relates to a method for positioning analysis in glow analysis.

Background technique

Shougang's sheet products are becoming more and more complete, and the output is also increasing. New products such as zinc, aluminum, magnesium, aluminum and silicon have also been mass-produced and supplied.

Glow discharge spectroscopic analysis is used in the detection of surface coating thickness and weight, passivation layer thickness and weight, chemical composition and other items of various types of thin plate samples such as zinc-aluminum-magnesium, aluminum-silicon, galvanized sheet, tin-plated sheet, etc., providing scientific research and development. A lot of valid data.

The basic principle of glow discharge spectroscopy is that the sample is used as the cathode, and the argon gas is ionized by high pressure in the copper anode. The element atoms are excited in the anode to emit light, and the light beam is introduced into the light chamber. After being decomposed by the spectroscopic system, the intensity of the characteristic spectral line can be detected, so that the element composition distribution of the sample from the surface to the inside can be obtained.

When using the glow discharge spectrometer, the GDS850A of the United States, the surface to be measured needs to be adsorbed on the anode port. The diameter of the anode port is 4 mm. The area of the sample surface corresponding to the anode port with a diameter of 4 mm is the analysis area. The diameter of the sealing ring at the outer edge of the mouth is 12 mm, and the diameter of the sample is generally 30 to 50 mm. In addition, the space of the sample analysis chamber is narrow, and when the sample is adsorbed on the anode port, the analysis position cannot be accurately positioned to a certain position on the sample surface. However, samples such as zinc-aluminum-magnesium, aluminum-silicon, and galvanized sheets often form abnormal areas with different colors or lines on the surface of the samples due to the influence of production processes and environmental conditions. Researchers often need to designate a certain area for glow spectrum analysis. It is used to observe the difference of surface element composition between abnormal area and normal area.

Therefore, there is a need to define a method for localization analysis in glow analysis.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a method for positioning analysis in glow analysis, which solves the problem that accurate positioning cannot be performed in glow analysis. Use the self-made positioning tool to determine the position of the back of the designated detection area to achieve the alignment of the designated detection area and the anode port, so as to realize the glow analysis of the designated detection area on the sample surface.

A method for positioning analysis in glow analysis, the specific steps and parameters are as follows:

1. Make a positioning tool 8, prepare an iron wire with a diameter of 1~3mm and a length of 10~20cm, connect its head and tail to make it deform into a square, keep its head and tail facing each other, and stick tape on both ends of the head and tail to prevent Scratch the surface of sample 1. Use this self-made positioning tool 8 to clamp the sample 1, one end is aligned with the designated detection area 6, and the other end is directly opposite the back of the designated detection area 7;

2. Mark the back 7 of the designated detection area with a marker, and draw a circle with a marker along the 8 end of the self-made positioning tool aligned with the back 7 of the designated detection area;

3. When the sample 1 is adsorbed to the anode port 2, insert a plastic tube 5 with a diameter of 4 mm into the anode reamer 4, and the other end of the plastic tube 5 faces the sample 1, and then move the sample 1 adsorbed on the anode port 2. , adjust its position so that the mark made before coincides with the plastic tube 5; since the anode reamer 4 and the anode port 2 are strictly aligned, the plastic tube 5 is directly connected with the anode reamer 4, and the designated detection can be ensured at this position. The area 6 is directly opposite to the anode port 2 and coincides with the marked position, and the glow spectrum analysis of the designated detection area 6 is completed.

The invention has the advantages of simple operation, using a self-made positioning tool to determine the back position of the designated detection area of the sample to achieve the centering of the designated detection area of the sample and the anode port, thereby realizing the glow analysis of the designated detection area on the surface of the sample.
