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.
Segurtasun Informazioa
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.
Konfigurazioa eta Prestaketa
Before beginning any measurements, ensure you have the following:
- YSI 251398Y DPD Free Chlorine Reagent Powder pack
- Compatible colorimeter or spectrophotometer
- Garbitu sample cells/vials
- Deionized or distilled water for blanks and dilutions (if necessary)
- Ura sample to be tested
- Tenporizadorea
Prestaketa urratsak:
- 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.
Funtzionamendu-argibideak
Follow these steps to accurately measure free chlorine using the YSI 251398Y DPD Free Chlorine Reagent Powder:
- Sample Bilduma: 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.
- Gehitu erreaktiboa: 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 sample cell.
- Nahasketa: Txapela 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.
- Erreakzio denbora: 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.
- Neurketa: 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.
- Erregistroaren emaitzak: Record the measured free chlorine concentration.

Mantentzea eta biltegiratzea
Proper storage and handling are crucial for maintaining the integrity and effectiveness of the reagent powder:
- Biltegiratzea: 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.
- Iraupena: Refer to the expiration date printed on the packaging. Do not use expired reagents, as they may yield inaccurate results.
- Xedapena: Dispose of used reagent and sample solutions according to local environmental regulations. Consult your local authorities for proper chemical waste disposal procedures.
- Garbitasuna: Always ensure sample cells and equipment are thoroughly cleaned after each use to prevent cross-contamination.
Arazoak konpontzea
If you encounter issues during testing, consider the following common problems and solutions:
| Arazoa | Kausa posiblea | Irtenbidea |
|---|---|---|
| No color development | No free chlorine present; Expired reagent; Incorrect sample bolumena. | Egiaztatuample contains chlorine; Check reagent expiration date; Ensure 5ml sample bolumena. |
| Fading color or inaccurate reading | Reaction time exceeded; Contaminated sample cell; Turbidity in sample. | Adhere strictly to 1-minute reaction time; Clean sample cells thoroughly; Filter turbid sampbehar izanez gero. |
| Emaitza ez-koherenteak | Improper mixing; Temperature variations; Colorimeter not calibrated. | Ensure complete dissolution of powder; Perform tests at consistent temperatures; Recalibrate colorimeter. |
