방법 교체 시약 추적 수분 분석기
1. 준비 a 청소 필터 종이, 제거 둘 건조 튜브 의 전해 셀 및 장소 그들 켜기 필터 종이; 테이크 아웃 전해 전극, 붓기 밖으로 the 전해질 in the 음극 챔버 (전해 전극), and then slowly pour out the electrolyte in the anode chamber (전해질 cell bottle) (be careful not to pour out the stirrer)
In general, it is not necessary to clean the electrolytic cell. After being contaminated, it is necessary to strictly follow (3) for cleaning
3. 청소: 전해질 셀 병, 건조 튜브, 밀봉 플러그, 및 측정 전극 캔 베 세정 포함 무수 메탄올 또는 기타 무수 용매, and if necessary, 그들 그들 또한 be cleaned with water; The cathode chamber (전해질 전극) should not be cleaned with water as much as possible. 언제 청소 with water, it must be 효과적으로 건조. 후 청소, it should be dried in an oven at about 60 degrees Celsius for 4 hours, and then cooled naturally in the oven. Note: the two plugs, wires, and rubber hoses should not touch the cleaning solution during cleaning.
4. 적용 a 레이어 의 진공 그리스 고르게 to the 연삭 표면 of the 측정 전극, two 건조 튜브, injection cock, and sealing port, and install it in the corresponding position. Gentlely rotate it to ensure a good sealing. Inject approx 100-120 milliliters of electrolyte into the negative and positive chambers of the moisture analyzer using a funnel to maintain the same liquid level in the negative and 포지티브 챔버. 그만큼 액체 레벨 해야 할울드 도달 그 마크 아래 그의 전해 셀. Then, install the sealing plug and drying tube, and gentlely rotate them to ensure a good seal.
5. Insert the measuring electrode plug of the electrolytic cell into the measuring socket of the host, and insert the electrolytic electrode plug into the electrolytic socket of the host. Shake the pool a few times, turn on the electrolysis and stirring keys, and if it is in a state of excessive iodine, use 50 μ 1. Inject an appropriate amount of pure water into the electrolytic cell (the needle should be inserted into the liquid surface) using the injector, and observe the color of the electrolyte at any time until counting begins. Turn off the stirring and evenly shake the electrolytic cell to fully react with the moisture and electrolyte in the air inside the cell. Then turn on the stirring and allow the instrument to reach the endpoint again, and then proceed with the sample injection test.
6. The storage color of the electrolyte is brownish red or brownish black. The color is light yellow during normal use.
7. 실패 의 전해질: 만약 거기 아는 둘 의 다음 셋 조건, 그것 할 수 있다 실패. (1) 사용 그의 전해질 for at least one month; (2) The color of the electrolyte darkens (in non iodine state); (3) The electrolysis process is difficult to reach the end point [after repeatedly shaking the electrolyly cell several times according to step 5].
8. When it is difficult to reach the endpoint during use due to high environmental humidity, hot air, frequent sampling, leakage of the silicone pad at the injection port, or difficulty in dissolving solid samples, simply shake the electrolytic cell evenly according to (5).
9. 주의: 언제 변화 시약, be 조심스러운 not to 흡입 또는 만지기 그의 시약 with 당신의 손. If in contact with the reagents, rinse them 철저하게 with water. 기한 to the strong odor and toxic components of the reagent, the ventilation in the laboratory should be good.
