⚗️ How to identify if your 3000 ppm CDS is of good quality

Summary: Learn to recognize quality CDS by analyzing its appearance, smell, concentration, and storage methods.

What is CDS?

CDS (Chlorine Dioxide Solution) is a saturated aqueous solution of chlorine dioxide (ClO₂) used as a biocide, disinfectant, and water purifier. Its popularity has grown due to its high effectiveness in technical disinfection and microbiological control.

Keys to identifying a quality CDS

• Color: It should be a light straw yellow. If it's completely clear, it may be diluted; if it's brown, it could be opacified.
• Odor: Light chlorine aroma. A weak odor indicates loss of concentration; a strong odor may indicate poor preparation.
• Concentration: Measurable with ppm equipment. The standard is 3000 ppm for well-saturated solutions.
• Packaging: Opaque glass only and refrigerated (4°C). Plastic degrades the product and reduces its shelf life.

How to check it at home

• Use test strips or a digital ppm meter.
• Check the manufacturing date and shelf life (usually 6 months refrigerated, 2 weeks opened).
• Observe if it produces a light cold mist when opened (indicates gasification).

Precautions

• Do not shake or expose to heat.
• Do not mix with other chemicals without knowledge of reactions.
• Keep out of reach of children.
