3. Sąranka
Before conducting any tests, ensure you have a clean, well-lit workspace. Familiarize yourself with all components of the kit.
- Unpack all components from the protective case.
- Inspect the glass test tubes for cleanliness. Rinse with distilled water if necessary and allow to air dry.
- Ensure the Wide Range pH indicator bottles are securely capped when not in use.
4. Naudojimo instrukcijos
Follow these steps to accurately measure the pH of your water sample using the colorimetric method:
- Surinkite vandenį SampLe: Fill one of the 5 mL glass test tubes to the 5 mL mark with the water sample to be tested. Ensure the sample is representative of the water source.
- Pridėti indikatorių: Add five (5) drops of the Wide Range pH indicator solution to the water sample in the test tube.
- Sumaišykite: Cap the test tube and invert it several times to thoroughly mix the indicator with the water sample. Do not shake vigorously, as this can introduce air bubbles.
- Spalvų vystymasis: Allow a few moments for the color to develop. The color of the solution will change based on the pH level.
- Compare Color: Place the test tube into one of the Octet Comparators. Hold the comparator against a white background in good lighting. Compare the color of the sample solution to the color standards on the comparator.
- Read pH Value: Identify the color standard that most closely matches the color of your sample. The corresponding number on the comparator is the pH value of your water sample. If the color falls between two standards, estimate the pH value.
- Rezultatų įrašai: Note down the pH reading for your records.
5. Priežiūra
Proper maintenance ensures the longevity and accuracy of your testing kit.
- Clean Test Tubes: After each use, thoroughly rinse the glass test tubes with clean water, preferably distilled or deionized water, to remove any residual indicator or sample. Allow them to air dry completely before storing.
- Store Reagents: Keep the pH indicator solutions tightly capped and store them in a cool, dark place, away from direct sunlight and extreme temperatures. Improper storage can affect reagent stability and accuracy.
- Patikrinkite galiojimo datas: Periodically check the expiration dates on the indicator solution bottles. Expired reagents may yield inaccurate results and should be replaced.
- Dėklo saugojimas: Store all components back in the protective case when not in use to prevent damage and contamination.
6. Problemų sprendimas
If you encounter issues with your pH testing, consider the following:
- Netikslūs rodmenys:
- Ensure test tubes are clean and free from contaminants.
- Verify that the indicator solution has not expired.
- Confirm the correct number of indicator drops was added.
- Ensure proper mixing of the sample and indicator.
- No Color Change or Faint Color:
- s pHample may be outside the kit's 3.0-10.5 range.
- The indicator solution may be expired or degraded.
- Spalvų derinimo sudėtingumas:
- Ensure good, consistent lighting, preferably natural daylight. Avoid direct sunlight or fluorescent lights that can alter color perception.
- Hold the comparator against a plain white background.
