Glycine 20% w/v (For Chlorine & Chlorine Dioxide Analysis)
Manufacturer: LabChem Inc.
Glycine, 20% w/v, for Chlorine and Chlorine Dioxide from LabChem Inc. is a specialized analytical reagent used for the selective determination of chlorine dioxide ($ClO_2$) in the presence of free chlorine. This high-concentration 20% formulation provides double the masking capacity of standard solutions, making it ideal for samples with high residual chlorine levels. In colorimetric DPD (N,N-diethyl-p-phenylenediamine) procedures, free chlorine creates a red color that interferes with the specific measurement of chlorine dioxide. The addition of this Glycine solution instantly converts free chlorine into chloroaminoacetic acid, which is non-reactive with DPD, allowing for an accurate, isolated reading of the chlorine dioxide concentration.
Description
This 500 mL unit provides high-volume testing capacity for industrial water treatment and municipal disinfection monitoring.
Features:
- Enhanced Masking Power: The 20% w/v concentration is optimized for industrial applications where high free chlorine residuals are common, ensuring complete interference suppression
- Precision Reproducibility: Manufactured to strict quality control standards to ensure consistent pH and purity, which is vital for the stability of the DPD reaction
- Laboratory Ready: Pre-mixed to eliminate the labor-intensive process of dissolving high concentrations of glycine powder, reducing the risk of errors in the lab
- Rapid Reaction Kinetics: Provides near-instantaneous conversion of free chlorine, allowing for fast, high-throughput field and benchtop testing
Safety & Regulatory Information:
Analytical Sequence:To ensure valid results, the Glycine solution must be added to the sample and mixed thoroughly before adding the DPD colorimetric reagents.
- Personal Protection: Wear nitrile gloves, splash-resistant goggles, and a lab coat.
- Storage: Store at room temperature in the original, tightly closed container. Keep away from strong oxidizers, acids, and bases.
- Stability: Inspect for clarity before use. High-concentration glycine solutions may precipitate if exposed to extreme cold; store above 10°C (50°F).
