Ukuqeda Ukungcoliswa Okungabonakali kanye Nemiphumela Yenkumbulo (B, Ti, Zr) Emijikelelweni Yokuhlanza Ngokugaya Nge-Microwave

Ekuhlaziyeni okungenasici nokuphezulu kakhulu kwe-inorganic kusetshenziswa i-ICP-MS ne-ICP-OES, ukuthola imikhawulo yendlela yokuthola engaphansi kwe-ppb ne-ppt ezingavikeleka kuncike ngokuphelele ekuhlanzekeni kwezitsha. Abahlaziyi abasebenzisa amasampula e-geological ane-matrix ephezulu, ama-alloys e-aerospace, noma ama-ceramics athuthukile kumapulatifomu afana ne-CEM MARS 6, Milestone ETHOS, ne-Anton Paar Multiwave bavame ukuhlangabezana nenkinga eqhubekayo: ​ukungcola okungabonakali nokudluliselwa kwenkumbulo kwezinto ezinzima ukuncibilika njenge-Boron (B), Titanium (Ti), Zirconium (Zr), ne-Hafnium (Hf)​. Ngisho nangemva kwemijikelezo eqinile yokuhlanza nge-microwave steam ye-nitric acid enengcindezi ephezulu, ama-blanks e-procedural aqhubeka ekhombisa amasignali angemuva aphakeme, angazinzi okonakalisa ukulinganisa okuncane.
Ukungcoliswa okungabonakali kwezinto ezingashiswa kalula i-B Ti Zr eziboshwe ngaphakathi kwesitsha sokugaya nge-microwave ngesikhathi sokuhlaziywa kwe-ICP-MS

Okubalulekile Okutholwayo

  • Indlela Yokusebenza Kwe-Memory Effect:
  • Kungani Ukuhlanza Nge-Acid Steam Kuhluleka Ezitsheni Ezindala: ukuhlanza kabusha nge-acid
  • Isixazululo Sobunjiniyela: Izitsha ze-TFM eziguqulwe zaba yi-isostatic density ephezulu () ezinendawo yangaphakathi ekhazimulayo kakhulu, engenazimbobo

Indlela Yokungena Kwe-Ion Ngaphansi Komhlaba Kanye Nokuhlanza Kabusha

2. I-Micro-Cavitation & Mechanical Strain
Ukushintshashintsha kwezinga lokushisa nokukhululwa kwengcindezi kubangela i-micro-crazing kanye nemifantu yengcindezi odongeni lwangaphakathi
Ukugcinwa ngaphansi komhlaba kwama-fluoride e-metal ahlanjululwe kanye nama-oxide complexes ekujuleni kwemifantu emincane
3. Ukuhlanza nge-Acid Steam Okujwayelekile
I-High-purity concentrated
HNO

umjikelezo we-steam uqhutshwa ukuze kuhlanjululwe i-rotor assembly
I-steam iphasivetha indawo yangaphandle kodwa yehluleka ukungena ezindaweni ezincane ezijulile ngaphandle kwezikhathi zokucwiliswa ngokwedlulele
4. Ukusetshenziswa kwe-Analytical Blank
I-blank run entsha ishisiswa emazingeni okushisa aphezulu phakathi nokulandelana kwamasampuli okulandelayo
