Embodiment 1

[0030] The invention provides an ionic liquid, specifically, a 1-ethyl-3-methylimidazolium tetrafluoroborate ionic liquid.

Embodiment 2

[0032] The invention also discloses the use of the 1-ethyl-3-methylimidazolium tetrafluoroborate ionic liquid to conduct conductive treatment on insulating samples before SEM-EDX detection.

[0033] Generally, the 1-ethyl-3-methylimidazolium tetrafluoroborate ionic liquid needs to be diluted during use, and the diluent used is ethanol and / or acetone; the 1-ethyl-3-methyl After the imidazolium tetrafluoroborate ionic liquid is mixed with the diluent, a diluent is formed;

[0034] In the diluent, the mass fraction of the 1-ethyl-3-methylimidazolium tetrafluoroborate ionic liquid is any one of 0.01%, 0.1%, 0.5%, 1%, and 5%.

[0035] The use of diluent can reduce the viscosity of 1-ethyl-3-methylimidazolium tetrafluoroborate ionic liquid, and can form a thinner ionic liquid film layer, which is more conducive to the subsequent SEM-EDX detection.

Embodiment 3

[0037] The present invention also provides a SEM-EDX detection method using the 1-ethyl-3-methylimidazolium tetrafluoroborate ionic liquid as a conductive treatment agent, to be located in Sakurajima, Kagoshima County, Kyushu, Japan Take the SEM-EDX detection of volcanic ash collected from a volcano (E31°35′N 130°39′) as an example, including the following steps:

[0038] a. Determine the nature of the sample to be tested: there are 5 insulating samples (volcanic ash) to be tested, and the particle size of each volcanic ash is between 50 and 100 μm, that is, they are all greater than 10 μm, and they are all insulators. The volcanic ash is subjected to conductive treatment;

[0039] b. Preparation of ionic liquid diluent: at room temperature, mix 1-ethyl-3-methylimidazolium tetrafluoroborate ionic liquid and diluent to form a diluent;

[0040] The diluent is a mixture of ethanol and acetone in an equal mass ratio; in the diluent, the mass fraction of the 1-ethyl-3-methylimidaz...

Description

technical field [0001] The invention belongs to the field of chemistry, and in particular relates to a SEM-EDX detection method using the 1-ethyl-3-methylimidazolium tetrafluoroborate ionic liquid as a conductive treatment agent. Background technique [0002] SEM is the abbreviation of Scanning Electron Microscope. It mainly uses secondary electron signal imaging to observe the surface morphology of samples, and uses point-by-point imaging to obtain enlarged images. In actual use, SEM is often used in combination with EDX; EDX stands for Energy Dispersion The abbreviation of X-ray spectrometer, SEM and EDX are used together as scanning electron microscope energy spectrometer for energy spectrum analysis. [0003] When performing SEM-EDX detection, the sample to be tested needs to be conductive. Therefore, before observing the insulating sample, it is necessary to use metal or carbon to conduct conductive treatment on the insulating sample, and then observe after forming a co...
