The YSI 251398Y DPD Free Chlorine Reagent Powder is designed for accurate measurement of free chlorine in water samples using a compatible colorimeter. Each pack contains 100 individual powder packs, with each pack formulated for a 5ml sample volume and capable of measuring free chlorine in the range of 0 to 3.5 mg/L.
This reagent utilizes the DPD (N,N-Diethyl-p-phenylenediamine) method, which reacts with free chlorine to produce a magenta color, the intensity of which is proportional to the chlorine concentration and measured by a colorimeter.
اطلاعات ایمنی
Always handle chemical reagents with care. Read the Safety Data Sheet (SDS) for this product before use. Wear appropriate personal protective equipment (PPE), including safety glasses and gloves, when handling the reagent powder. Avoid ingestion and contact with skin or eyes. In case of contact, rinse thoroughly with water and seek medical attention if irritation persists.
راه اندازی و آماده سازی
Before beginning any measurements, ensure you have the following:
- YSI 251398Y DPD Free Chlorine Reagent Powder pack
- Compatible colorimeter or spectrophotometer
- تمیز sample cells/vials
- Deionized or distilled water for blanks and dilutions (if necessary)
- آب اسampباید آزمایش شود
- تایمر
مراحل آماده سازی:
- Ensure all glassware and sample cells are clean and free from contamination. Rinse with deionized water before use.
- Calibrate your colorimeter according to its specific instruction manual before use.
دستورالعمل های عملیاتی
Follow these steps to accurately measure free chlorine using the YSI 251398Y DPD Free Chlorine Reagent Powder:
- Sampمجموعه le: Collect a fresh water sample in a clean sample cell. The required volume is 5ml. Ensure the sample is representative of the water being tested.
- اضافه کردن معرف: Carefully tear open one YSI 251398Y DPD Free Chlorine Reagent Powder pack. Add the entire contents of the powder pack to the 5ml water sample در sampسلول لو
- مخلوط کردن: درپوش sample cell and invert several times to thoroughly mix the reagent with the sample. Ensure all powder dissolves completely. A magenta color will develop if free chlorine is present.
- زمان واکنش: Allow a reaction time of 1 minute for the color to fully develop. Do not exceed 6 minutes, as color fading may occur, leading to inaccurate results.
- اندازه گیری: Insert the prepared sample cell into your calibrated colorimeter. Follow your colorimeter's instructions to initiate the measurement. The colorimeter will display the free chlorine concentration in mg/L.
- نتایج رکوردها: Record the measured free chlorine concentration.

نگهداری و ذخیره سازی
Proper storage and handling are crucial for maintaining the integrity and effectiveness of the reagent powder:
- ذخیره سازی: Store the reagent powder packs in their original packaging in a cool, dry place, away from direct sunlight and extreme temperatures. Do not store near strong acids or bases.
- ماندگاری: Refer to the expiration date printed on the packaging. Do not use expired reagents, as they may yield inaccurate results.
- دفع: Dispose of used reagent and sample solutions according to local environmental regulations. Consult your local authorities for proper chemical waste disposal procedures.
- پاکیزگی: Always ensure sample cells and equipment are thoroughly cleaned after each use to prevent cross-contamination.
عیب یابی
