유도결합플라즈마 질량분석기는 플라즈마(주로 Ar)로 분석대상 물질을 이온화 시키고 이를 질량분석기로 분석하여 시료 중의 극미량의 원소를 분석하는데 사용된다.
- Thermoelectrically controlled: -20~20 ℃로 휘발성 강한 유기용매 matrix 분석이 가능함. (spray-chamber)
- Q-Cell(quadrupole)방식: 낮은 분해능(0.7~1.0 amu)으로 반복적인 분석에 적합하며, 성능대비 경제적임.
- Auto-tuning 지원으로 장비담당자가 쉽고 빠르게 튜닝과정을 진행할 수 있음.
- Torch, injector, spray chamber 등 모두 원터치 연결 및 분해되어 사용 및 유지 보수가 편리함.
