8-3. Keeping of reagent for moisture measurement
The following API corporation reagents are taken as an examples.
Anode solution : AQUAMICRON
Cathode solution : AQUAMICRON
8-3-1. Keeping
For long-term keeping, keep it at the shade and cool space.
To keep AQUAMICRON
moisture interfusion.
8-3-2. Caution in handling
Place partial and overall ventilations in handling. Take care not to touch and inhale reagent.
If you touch reagent, wash it with much water.
For other details, refer to AQUAMICRON X-series instructions attached to a reagent bottle.
8-3-3. Reagent change
(1) Moisture measurement power of AQUAMICRON
about 800mg and 300mg. When they are diluted by samples and 150ml or more, electrolysis
efficiency is low and measurement values are high. Discharge all and replace them with new
reagent.
(2) Moisture measurement power of AQUAMICRON
reaction, air bubbles occur during measurement. If measurement continues, reagent is red-brown.
If measurement continues further, reagent is dark-brown and a liquid level is up gradually by
electro-osmosis. In this case, replace reagents with new ones. Take out old reagents with a pipette
and inject new ones. Do not add new reagents to old ones. When reagents absorb much moisture,
titration end points can't be detected. Change reagents every week.
