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.
معلومات السلامة
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.
الإعداد والتحضير
Before beginning any measurements, ensure you have the following:
- YSI 251398Y DPD Free Chlorine Reagent Powder pack
- Compatible colorimeter or spectrophotometer
- ينظفample cells/vials
- Deionized or distilled water for blanks and dilutions (if necessary)
- المياه قample to be tested
- الموقت
خطوات التحضير:
- 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.
تعليمات التشغيل
Follow these steps to accurately measure free chlorine using the YSI 251398Y DPD Free Chlorine Reagent Powder:
- Sampمجموعة لو: 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.
- Add Reagent: Carefully tear open one YSI 251398Y DPD Free Chlorine Reagent Powder pack. Add the entire contents of the powder pack to the 5ml water sampجنيه في sampلو الخلية.
- مزج: كاب ال 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.
- وقت رد الفعل: 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.
- قياس: 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.
- سجل النتائج: Record the measured free chlorine concentration.

الصيانة والتخزين
Proper storage and handling are crucial for maintaining the integrity and effectiveness of the reagent powder:
- تخزين: 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.
- مدة الصلاحية: Refer to the expiration date printed on the packaging. Do not use expired reagents, as they may yield inaccurate results.
- تصرف: Dispose of used reagent and sample solutions according to local environmental regulations. Consult your local authorities for proper chemical waste disposal procedures.
- نظافة: Always ensure sample cells and equipment are thoroughly cleaned after each use to prevent cross-contamination.
استكشاف الأخطاء وإصلاحها
If you encounter issues during testing, consider the following common problems and solutions:
| مشكلة | السبب المحتمل | حل |
|---|---|---|
| No color development | No free chlorine present; Expired reagent; Incorrect sampحجم جنيه. | Verify sample contains chlorine; Check reagent expiration date; Ensure 5ml sampحجم جنيه. |
| Fading color or inaccurate reading | Reaction time exceeded; Contaminated sample cell; Turbidity in sampليه. | Adhere strictly to 1-minute reaction time; Clean sample cells thoroughly; Filter turbid sampليه إذا لزم الأمر. |
| نتائج غير متسقة | Improper mixing; Temperature variations; Colorimeter not calibrated. | Ensure complete dissolution of powder; Perform tests at consistent temperatures; Recalibrate colorimeter. |
