EDTA Reagent, 5% w/v, Nitrogen (Ammonia & Organic)
Manufacturer: LabChem Inc.
EDTA Reagent, 5% w/v from LabChem Inc. is a specialized analytical solution designed to mitigate matrix interferences during the determination of Ammonia Nitrogen (NH3-N) and Total Kjeldahl Nitrogen (TKN). In colorimetric methods like the Phenate or Nessler methods, high concentrations of Calcium and Magnesium in water samples can form precipitates that cloud the results. This reagent sequesters (chelates) those metal ions, ensuring a clear sample for accurate spectrophotometric measurement.

Lead Times May Vary.
Features:
- Interference Mitigation: Specifically prevents the formation of Calcium and Magnesium precipitates in hard water samples that otherwise cause "spikes" or turbidity in absorption spectra.
- EPA & APHA Standardized: Formulated to meet the precise requirements of regulatory water testing methods (e.g., APHA 4500-NH₃), ensuring audit-ready compliance.
- Ready-to-Use Accuracy: Eliminates the difficult task of dissolving EDTA powder into an alkaline matrix in-house, ensuring consistent molarity and performance.
- Versatile Application: Used across multiple nitrogen analysis techniques, including automated phenate, Nesslerization, and ammonia-selective electrode methods.
Safety & Handling
CAUTION! Alkaline Solution: This reagent contains Sodium Hydroxide and is alkaline. It may cause skin and eye irritation.
- Personal Protection: Wear standard lab PPE, including nitrile gloves, safety goggles, and a lab coat.
- Storage: Store at room temperature in the original poly bottle. Shelf life is typically 24 months.
- Disposal: Dispose of according to local environmental regulations for laboratory waste. Once used in samples containing mercury (Nessler reagent), the waste must be handled as hazardous mercury waste.
