As a leading laboratory testing service provider, Eurolab is committed to delivering high-quality analytical results that meet the strictest regulatory requirements. In this article, we will provide an in-depth guide to EPA 200.9 Mercury Determination by Cold Vapor Atomic Absorption (CVAA) in Water Samples testing, including standard-related information, test conditions and methodology, test reporting and documentation, and more.

STANDARD-RELATED INFORMATION

The analysis of mercury in water samples is governed by several international and national standards, including:

1. EPA Method 200.9: This method is approved by the US Environmental Protection Agency (EPA) for the determination of total mercury in drinking water.

2. ISO 11885:2017: This standard specifies the requirements for the determination of mercury in water using cold vapor atomic absorption spectrometry.

3. ASTM D7346-14: This standard provides a method for the analysis of mercury in water by cold vapor atomic absorption spectroscopy.

4. EN ISO 5665:1998: This European Standard specifies the requirements for the determination of mercury in water using cold vapor atomic absorption spectrometry.

These standards outline the procedures and protocols for collecting, preparing, and analyzing water samples for mercury content. They also specify the required equipment, reagents, and quality control measures to ensure accurate and reliable results.

STANDARD REQUIREMENTS AND NEEDS

The analysis of mercury in water samples is a critical component of environmental monitoring and regulation. Mercury is a toxic substance that can have adverse effects on human health and the environment. The presence of mercury in water sources poses a significant risk to public health, particularly for vulnerable populations such as infants and children.

The need for EPA 200.9 Mercury Determination by CVAA in Water Samples testing arises from various factors:

1. Regulatory compliance: Water treatment plants, industrial facilities, and municipalities must comply with federal, state, and local regulations regarding mercury levels in drinking water.

2. Environmental protection: The analysis of mercury in water samples helps to identify potential sources of contamination and inform remediation efforts.

3. Public health: Mercury testing ensures that drinking water meets safety standards and protects public health.

TEST CONDITIONS AND METHODOLOGY

The EPA 200.9 method requires the use of a cold vapor atomic absorption spectrometer (CVAA) equipped with a mercury-specific detector. The test involves several steps:

1. Sample collection: Water samples are collected from various sources, including tap water, surface water, and wastewater.

2. Sample preparation: Samples are filtered, preserved, and spiked with a certified reference material to ensure accurate results.

3. Instrument calibration: The CVAA is calibrated using a series of standard solutions to ensure instrument accuracy.

4. Analysis: The sample is introduced into the CVAA, where mercury is vaporized and detected by atomic absorption spectroscopy.

5. Data analysis: The resulting data are analyzed using specialized software to calculate the mercury concentration.

Eurolabs laboratory is equipped with state-of-the-art equipment and follows strict quality control procedures to ensure accurate results.

TEST REPORTING AND DOCUMENTATION

Test results are documented in a comprehensive report that includes:

1. Sample information: Sample ID, location, date, and time.

2. Methodology: Description of the analytical method used.

3. Results: Mercury concentration (μg/L) and confidence interval (CI).

4. Quality control measures: Information on sample preparation, instrument calibration, and data analysis.

Eurolabs reports are certified by our Quality Management System (QMS), ensuring compliance with regulatory requirements.
