Abstract
A plasma source with cylindrical microwave cavity was used as atomic emission detector for gas chromatography. Detection limits of several elements were determined for this system. Detection limits for bromine and sulfur were 0.46 pg/s and 0.51 ng/s, respectively. The plasma was stable at the range of flow rate of 10 to 20mL/min.
원통형 microwave cavity를 이용한 플라즈마 발생장치를 기체크로마토그라프에 연결하여 원자발광 검출기로 사용하였다. 이 장치를 이용하여 몇 가지 원소에 대한 검출한계를 결정하였다. 브롬과 황에 대한 검출한계는 각각 0.46 pg/s 와 0.51 ng/s였으며, 운반기체의 유량이 10~20 mL/min에서 안정한 플라즈마를 얻을 수 있었다.
