Precaucións de seguridade
Always handle chemical reagents with care. Wear appropriate personal protective equipment (PPE), including safety glasses and gloves, when handling SulfaVer 4 reagent. Refer to the Safety Data Sheet (SDS) for complete safety information. Do not ingest. Keep out of reach of children.
Configuración
- Gather Equipment: Ensure you have all necessary equipment, including a Hach colorimeter or spectrophotometer (e.g., DR-900), sample cells, a timer, and a 10 mL graduated cylinder or pipette for accurate sample medición.
- Preparar SampLe: Recoller unha cantidade representativa de augaample. O sample size required for Hach Method 8051 is 10 mL.
- Ensure Cleanliness: Use clean glassware and sample cells to prevent contamination, which can affect test results.
Operating Instructions (Hach Method 8051)
Follow these steps for accurate sulfate determination using Hach Method 8051:
- Preparar Sampa Célula: Fill a clean sample cell with 10 mL of the water sample. For a blank, fill another clean sample cell with 10 mL of deionized water.
- Engadir reactivo: Open one Hach SulfaVer 4 Powder Pillow. Add the entire contents of the powder pillow to the 10 mL sampa cela.
- Mestura: Tapa o sample cell and shake vigorously for 30 seconds to ensure the reagent dissolves completely and mixes thoroughly with the sample.
- Tempo de reacción: Permitir o sample to react for a specific time, typically 5 minutes. Refer to your Hach instrument's manual for the exact reaction time for Method 8051. During this time, a turbidity will develop if sulfate is present.
- Medida: After the reaction time, insert the prepared sample cell into your Hach colorimeter or spectrophotometer. Follow the instrument's instructions to select Hach Method 8051 and measure the sulfate concentration.
- Resultados do rexistro: Record the sulfate concentration displayed by the instrument.
Note: Always refer to your specific Hach instrument's operation manual for detailed instructions on performing Method 8051, as procedures may vary slightly between models.
Mantemento
- Almacenamento: Store Hach SulfaVer 4 Powder Pillows in their original packaging in a cool, dry place, away from direct sunlight and moisture. Ensure the resealable bag is properly closed after each use to protect unused pillows.
- Data de caducidade: Check the expiration date on the packaging. Do not use expired reagents, as they may yield inaccurate results.
- Eliminación: Dispose of used reagents and samples according to local environmental regulations. Consult your facility's waste disposal guidelines.
Resolución de problemas
| Problema | Causa posible | Solución |
|---|---|---|
| Resultados inexactos ou inconsistentes | Expired reagent, improper mixing, contaminated glassware, incorrect sample volume, instrument calibration issue. | Check reagent expiration date. Ensure vigorous mixing for 30 seconds. Use clean glassware. Verify 10 mL sample volume. Calibrate instrument as per manufacturer's instructions. |
| No turbidity development | Sulfate concentration is below detection limit, reagent not added, or reagent is expired. | Confirm sulfate presence with another method if possible. Ensure reagent was added. Check reagent expiration date. |
| Excessive turbidity or precipitate | High sulfate concentration exceeding range, interfering substances, or improper mixing. | Diluír sample if sulfate concentration is expected to be high and retest. Check for known interferences. Ensure proper mixing. |
