Precautions for using GSGG-5089 online silicon meter (2)

Regarding the preparation of reagents and standards

1. When users prepare reagents, they must use room temperature silicon free water and slowly dissolve them. Do not use an electric furnace or hot water for heating, as the prepared reagents may crystallize and precipitate, blocking the reagent pipelines and solenoid valves.

2. All drugs used for preparing reagents and standards are required to be of analytical grade or higher.

3. Ammonium molybdate is recommended to use products from Tianjin Chemical Reagent Plant 4 (Kaida Chemical Plant), as long-term use is unlikely to result in crystallization.

4. If crystallization occurs and the pipeline is blocked, it can be soaked in dilute ammonia water and then rinsed repeatedly with clean water. Ammonia water should not remain in pipelines and reagent bottles for a long time. Reagent bottles and solenoid valves are not resistant to ammonia water.

5. New reagent and standard bottles should be repeatedly rinsed with silicon free water to avoid contaminating the reagents and standards.

6. Because the actual silicon free water used may also contain a certain amount of silicon, and there may be some human error in the preparation process, the prepared standard sample may not meet the required accuracy. It is recommended to use a spectrophotometer to accurately measure the concentration value of the prepared standard sample, and then use it according to the actual measurement value.
