ISO 10304-4 Chlorate and Perchlorate Test in Water
The ISO 10304 series of standards provides a robust framework for analyzing chlorate and perchlorate in water. This service focuses on the specific requirements outlined in ISO 10304-4, which is dedicated to the determination of chlorate (ClO3-) and perchlorate (ClO4-) by ion chromatography. Chlorates and perchlorates are important analytes in water testing because they can have harmful effects on aquatic life and human health if present at high concentrations.
The chlorate and perchlorate levels in drinking water, surface water, and wastewater must be monitored to ensure compliance with regulatory standards such as those set by the US Environmental Protection Agency (EPA), the World Health Organization (WHO), and other international bodies. The method described in ISO 10304-4 is recognized for its precision, accuracy, and ease of use, making it a reliable choice for laboratories.
The test begins with proper sample preparation. Samples must be filtered to remove particulates and any potential interferences. This step ensures that the ion chromatography analysis yields accurate results. After filtration, the samples are analyzed using an ion chromatograph equipped with a suppressed conductivity detector. The method involves elution of chlorate and perchlorate ions from a column packed with specific stationary phases.
The analytical performance of this test is characterized by its detection limits, which are in the range of 0.1 to 0.5 mg/L for both chlorate and perchlorate depending on the sample matrix. The method also specifies precision and accuracy criteria that ensure reliable results. Precision is typically better than ±2%, while accuracy can be up to ±3% relative error.
The data obtained from this test are used in a variety of applications, including the monitoring of water treatment processes, compliance with drinking water standards, and environmental impact assessments. The results of these tests provide critical information for quality managers, compliance officers, R&D engineers, and procurement teams who need to ensure that their water sources meet regulatory requirements.
Our laboratory adheres strictly to ISO 10304-4 guidelines to deliver accurate and reliable test results. Our team of experts is well-trained in the nuances of this method, ensuring consistent and precise analyses. The results are reported in a clear format, including detailed method descriptions, raw data, and graphs illustrating the chromatographic peaks.
