Trước khi đặt in tem vỡ đảm bảo mỹ phẩm, doanh nghiệp cần chuẩn bị các loại giấy tờ theo quy định của pháp luật. Các giấy tờ chứng minh nguồn gốc xuất sứ của sản phẩm.
With this blog, we’ll check into The true secret discrepancies and programs of SEM vs. TEM, guiding you thru their functions, one of a kind functions, and how to select the ideal a single for your preferences.

A series of electromagnetic lenses and apertures are put through the microscope’s column to concentrate the beam to the sample, lower distortions, and Amplify the ensuing graphic on to a phosphor monitor or possibly a specialised camera.
The illumination supply (or electron gun) inside of a thermo-ionic emission TEM operates very like a light bulb. A filament (cathode) could be the supply of electrons. It is generally a hairpin-shaped tungsten wire. An accelerating voltage (mounted number of destructive superior voltage) is placed on the bordering cathode cap. A little emission existing is then applied to the filament to realize the release of electrons. The purpose at which the gun achieves superior thermal emission and also get more info an acceptable filament life is known as the saturation position.
Given that electrons are certainly tiny and simply deflected by hydrocarbons or fuel molecules, it's important to use the electron beam in the vacuum setting. A series of pumps are used to accomplish an adequate vacuum for this reason. Rotary Pumps are the very first in the series. They are also called the "roughing pumps" as These are utilized to initially decreased the stress throughout the column through which the electron need to journey to 10 -three mm of Hg vary.
This really is reached by coating the tungsten idea with a skinny layer of zirconium oxide (ZrO) which lowers the get the job done purpose Hence marketing thermal emission of electrons.
In this method, the particle for being studied is subjected to electron beams less than a higher-resolution microscope named a transmission electron microscope as well as micrographs or photos captured are analyzed computationally.
Each of the electrons will thus not reach a standard focus. To lower spherical aberration, an aperture is used to eliminate a lot of the periphery electrons.
Amongst the first criteria When picking among SEM and TEM is the extent of depth you'll need. TEM has the higher hand for tasks demanding atomic or molecular resolution, rendering it suitable for in-depth Assessment of interior constructions.
