분석기 작동의 원리는 측정될 물에 국부적인 방전을 (electric discharge)통해 검사중인 원소 원자의 emission radiation을 여기 한 다음 방사선 스펙트럼(radiation spectrum)을 기록하고 처리하는 데 기반합니다. 모든 원소의 방출 방사선(emission radiation line)의 강도는 분석된 물의 농도에 비례합니다.
Bourevestnik, JSC는 세계 최고의 분석계측기 설계 및 제조업체 중 하나로, 완전히 새로운 개발품인 Atomic Emission Spectral Analyzer – EMIS-3를 출시하였습니다.
EMIS-3은 Na, Mg, Ca, Al, K, Cu, Zn, Ba, Sr, Ag, Ni, Cd, Co, Pb 등 다양한 원소의 불순물을 포함하는 수생 환경(aquatic environment)의 정성적, 정량적 조성을 결정하도록 설계되었습니다. Bourevestnik의 과학적인 엔지니어링 잠재력은 고객의 필요에 따른 측정 원소 수를 늘릴 수 있도록 하였습니다.

OES analyzer EMIS-3 is designed to measure the mass concentration of various element ions in water media in the flow.
Principle of analyzer operation is based on the excitation of emission radiation of atoms of chemical elements being under examination by means of local electric discharge in analized water with the subsequent recording and processing of radiation spectrum. Intensity of the emission radiation lines of any element is proportional to its concentration in analized water.
Bourevestnik, JSC being one of the world’s leading designer and manufacturer of the instrumentation is glad to present a completely new development - Atomic Emission Spectral Analyzer – EMIS-3.
