▣ 일반적인 전기화학 실험용, 수은 비사용으로 친환경적

▣ 산성 용액에서 안정

▣ Chloride 이온방해 시 Hg/Hg2So4 전극 추천

▣ Ag와 complex를 형성하는 NH3 buffer 사용 금지

황화물 용액에서 사용 금지 (AgS 침전물 발생)

▣ Vycor tip junction : 비염기성 용액 사용 (알칼리에 약함)

▣ Ceramic tip junction

Ag/AgCl Reference Electrodes


* EC-Frontier

▣ 뛰어난 전위 재현성 및 사용 용이성

▣ 전극 전위 +0.199V vs. NHE 25℃ (sat. KCl)

▣ 소켓형 전극 wire adapter hole 직경: 0.5mm (RE-18, RE-19, RE-20 모델만 wire 교체 가능)

▣ Double Junction 전극 지원(RE-22A, RE-7A, RE-8A 모델만 해당)

▣ Double Junction 전극 사용 예시

- Ag/AgCl 전극 내 Ag와 Sample이 반응할 경우

- 단백질, 황, 중금속 포함 용액

- 강한 환원제 이온이 첨가되었을 경우

- Tris buffer를 사용할 경우

- 장시간 동안 전위를 안정화시키고 싶거나, 용액이 혼입되는 것을 방지하기 위해 사용
