4. Configuració
Before performing a test, ensure you have the following:
- Hanna Instruments HI93701-03 Free Chlorine Reagents.
- A compatible Hanna Instruments photometer or colorimeter.
- Clean cuvettes (glass or plastic, as specified by your instrument).
- Distilled or deionized water for blanking and cleaning.
- Un temporitzador.
- Equip de protecció individual (EPI).
Ensure your photometer is calibrated and ready for use according to its specific instruction manual.
5. Instruccions de funcionament
The following steps outline the general procedure for using HI93701-03 reagents. Always refer to your specific photometer's instruction manual for detailed operating procedures, as steps may vary slightly.
- Prepara la SampLI: Recollir una aigua sample en un recipient net. Assegureu-vos que el sample is representative of the water to be tested.
- Zero the Instrument:
- Fill a clean cuvette with 10 mL of the unreacted water sample (or distilled/deionized water if specified by your instrument for blanking).
- Insert the cuvette into the photometer and follow the instrument's instructions to zero it. This step compensates for any color or turbidity in the sampel mateix.
- Afegir reactiu:
- Open one packet of HI93701-0 Free Chlorine Reagent.
- Add the entire contents of the powder packet to a second clean cuvette containing 10 mL of the water sample.
- Cap the cuvette and shake gently for approximately 20 seconds to dissolve the reagent completely. A pink color will develop if free chlorine is present.
- Temps de reacció: Allow a reaction time of 1 minute. This ensures full color development.
- Measure the SampLI:
- After the reaction time, insert the cuvette with the reacted sample into the photometer.
- Follow the instrument's instructions to take a reading. The photometer will display the free chlorine concentration, typically in mg/L (ppm).
- Resultats del registre: Note down the measured free chlorine concentration.
6. Manteniment i emmagatzematge
Proper maintenance and storage are crucial for the longevity and accuracy of the reagents.
- Emmagatzematge: Store HI93701-03 reagents in their original packaging in a cool, dry place, ideally between 18°C and 25°C (64°F and 77°F). Avoid exposure to direct sunlight, extreme temperatures, and high humidity.
- Data de caducitat: Do not use reagents past their expiration date, as indicated on the packaging. Expired reagents may yield inaccurate results.
- Manipulació: Always handle reagent packets with clean, dry hands to prevent contamination.
- Eliminació: Dispose of used reagents and empty packets responsibly, following all local environmental regulations for chemical waste.
