주요 특징

Sigray QuantumLeap™은 Synchrotron와 같은 성능을 갖춘 최초의 실험실 X-ray absorption spectroscopy(XAS)이며 Oxidation states, Bond lengths, Interatomic distances, Electron symmetry 등에 대한 중요한 정보를 제공합니다.

Application

• 촉매 : 산화물, 질소화물 및 탄소화물의 화학적 상태(Cluster 크기 분석
• 배터리/연료전지/태양전지 : 충전 및 방전주기의 함수로서 전이 금속(e.g : Lithium ion batteries)의 산화 상태 분석
• 나노입자 : 구조, 크기, 구성의 특성화 분석
