Along with inviting doctor fish and people who have knowledge in gems to prove it.
latest Assoc. Prof. Dr. Weerachai Puttawong or Ajarn Aod Lecturer at Department of Chemistry Faculty of Arts and Sciences Kasetsart University has revealed that The blue gem that was the news It’s actually a normal colored glass with lead.
“From this morning, Doctor Pla and journalists and uncle, the owner of 300 million Kot Ploy, brought samples. Ort extracted and analyzed. The results clearly indicated that it was a normal colored glass. Importantly, there is lead mixed in.
The analyzer used is FE-SEM/EDS, Field emission Scanning Electron Microscope and Energy Dispersive X-ray Spectroscropy, Brand: Tescan, Model: MIRA3.
scanning electron microscope Field Emission Type (FESEM) is an electron microscope capable of imaging up to 1,000,000x high magnification and capable of analyzing the constituent elements of samples by X-ray energy diffusion (EDS) technique. semi-quantitative (Semi-Quantitative) Applications Take pictures of cultured cells, microorganisms, particles and fibers that can be transfected up to the nanoscale. An enlarged view of the polymer blend to see the distribution of the different phases. Elemental analysis of alloys, etc.
Thank you Assistant Professor Dr.Waya Puttawong, Lecturer, Department of Chemistry, Faculty of Science, Silpakorn University. that help forward the FE-SEM/EDS technique.”
