ISO 17782 Determination of Organic Residues in Wastewater
The ISO 17782 standard provides a robust method for the determination of organic residues in wastewater, which is essential for monitoring and ensuring compliance with environmental regulations. This service plays a critical role in safeguarding public health and maintaining ecological balance by identifying and quantifying organic pollutants present at trace levels.
Organic residues in wastewater can include a wide range of contaminants such as pharmaceuticals, personal care products, industrial chemicals, and other xenobiotics. These substances often persist in the environment due to their stability and resistance to degradation processes. The ISO 17782 method enables accurate quantification using advanced analytical techniques like High-Performance Liquid Chromatography (HPLC) coupled with Mass Spectrometry (MS).
The procedure involves several key steps, starting from the collection of wastewater samples. Proper sample handling is crucial to prevent degradation or contamination of the organic residues being analyzed. Following this, the samples undergo a series of preparatory treatments designed to concentrate and purify the target analytes before analysis.
Once prepared, the samples are injected into an HPLC instrument equipped with appropriate columns tailored for separating complex mixtures of organic compounds. Subsequent detection typically involves MS, allowing for identification based on molecular weight and fragmentation patterns. The resulting data provides quantitative results expressed in terms of parts per billion (ppb) or micrograms per liter (µg/L).
The accuracy and precision of the ISO 17782 method are paramount given its importance in environmental monitoring programs. Compliance with this standard ensures reliable measurement across various matrices, including domestic sewage, industrial effluents, and surface waters.
Our laboratory adheres strictly to all relevant international standards, ensuring that our clients receive accurate, reproducible results.

Scope and Methodology
The scope of the ISO 17782 method encompasses a wide array of organic residues that may be present in wastewater. These residues are typically categorized into groups such as pharmaceuticals, pesticides, industrial chemicals, and personal care products. The primary goal is to quantify these contaminants at trace levels, providing valuable insights for environmental management.
- Pharmaceuticals
- Pesticides
- Industrial Chemicals
- Personal Care Products
The methodology involves several stages: sample collection, preparation, extraction, clean-up, and finally analysis via HPLC-MS. Each step is meticulously controlled to minimize interferences and ensure accurate quantification.
Sample collection adheres to best practices outlined in ISO 17782, emphasizing the use of appropriate containers and preservation methods to maintain integrity throughout transport to the laboratory. Once received, samples are processed according to established protocols that include dilution, solid-phase extraction (SPE), or liquid-liquid extraction depending on the nature of the contaminants.
Following preparation, concentrated extracts undergo further purification using SPE cartridges pre-packed with suitable sorbents. This step enhances sensitivity and reduces matrix effects during analysis. Finally, the purified extracts are injected into an HPLC instrument configured for optimal separation capabilities.
The analytical technique employed is High-Performance Liquid Chromatography (HPLC) coupled with Mass Spectrometry (MS). This combination offers high resolution and selectivity necessary for detecting low-concentration organic residues. Data processing involves alignment, calibration, and quantification using established reference materials.
