The placement of instruments
1, a cool place, indoor temperature 5 ℃ ~ 35 ℃.
2. Do not install the instrument in an environment with high humidity and large fluctuation of power supply.
3. Do not work in an environment with corrosive gases.
2. Replacement of silicone pad
The long use of the silicone pad of the sample injection port will make the pinhole become non-contractile, so that the moisture in the atmosphere will enter and the impact of the determination should be replaced in time.
Iii. Dry silica gel replacement
When the silica gel of the drying tube is changed from blue to light blue, the new silica gel should be replaced, and the silica gel powder should not be loaded. Otherwise, the electrolytic pool will not be able to exhaust, and the electrolysis will be terminated.
4. Maintenance of electrolytic pond
Every 7 ~ 8 days to turn the mill inlet of electrolytic cell, when can't easily turn again to reload after coated with a thin layer of vacuum grease, otherwise, use a long time is not easy to be removed.
5. Electrode plug and socket maintenance
The measuring electrode, the plug of the electrolyte electrode, the outlet of the regular activity, will make the contact bad, because of regular wipe, and avoid contact with corrosive liquid.
Vi. Cleaning of electrolytic pool
Open the glass opening of all the electrolytic tank, the electrolytic tank, the drying tube and the sealing plug can be washed with water.
Within about 80 ℃ oven to dry after cleaning and natural cooling.
The electrolytic electrode can not be cleaned with water, can be cleaned with acetone, no water ethanol, and dried with a hair dryer after cleaning.
Should be careful when cleaning, do not clean the electrode lead.
7. Replace the electrolyte process
1. Remove the electrolyte electrode, measuring electrode, drying tube, sample plug and other accessories from the electrolytic tank
Remove the electrolyte you want to replace from the electrolytic tank
Clean the electrolyte bottle and electrolyte electrode and measure electrode with anhydrous ethanol
4 will be clean after electrolytic electrode and electrolytic cell, such as in not above 50 ℃ oven drying
Pour the new electrolyte into the electrolytic tank and pour in about 150Ml (between the two white horizontal lines in the electrolytic pool)
6. Install the electrolyte electrode, the measuring electrode and the drying tube into the sample plugs, and pour the new electrolyte into the electrolyte electrode. The amount of the liquid is equal to the level of the electrolyte level in the electrolytic tank
All the grinding points of the electrolytic cell (electrolytic electrode, measuring electrode, feeding plug, glass grinding plug) are coated with vacuum grease.
Put the changed electrolytic tank into the instrument's electrolytic tank holder and open the instrument to the determination state.
The new reagent should be reddish-brown, in iodine-state, with 50uL injector injection of approximately 50-100ul water until the reagent becomes light yellow.
