ISO 11885 Multi-Metal Analysis in Food by ICP-OES

The ISO 11885 standard outlines a method for multi-metal analysis using Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) in food and feed samples. This testing service is designed to provide comprehensive analysis of heavy metals and toxic elements that may be present in various food products, ensuring compliance with international food safety regulations.

The analytical process involves several critical steps: sample preparation, digestion using concentrated acids, and subsequent introduction into the ICP-OES instrument for precise measurement. This method allows for the detection of trace levels of heavy metals such as lead (Pb), cadmium (Cd), mercury (Hg), arsenic (As), and others, which can be harmful if present in excess quantities.

The analytical precision and accuracy provided by this method are unparalleled due to the high sensitivity and resolution of ICP-OES. This makes it an indispensable tool for quality managers, compliance officers, R&D engineers, and procurement specialists who need reliable data on metal content to ensure product safety and regulatory compliance.

For accurate results, samples must be thoroughly prepared following ISO 11885 guidelines. Sample preparation includes digestion in a mixture of nitric acid (HNO3) and perchloric acid (HClO4). After thorough digestion, the solution is filtered to remove any insoluble residues before analysis by ICP-OES.

The instrument used for this analysis combines high temperature plasma excitation with optical emission spectroscopy. It provides a non-destructive method of detecting metals in complex matrices such as food and feed products. The precision of this technique allows us to identify even minute concentrations of heavy metals, ensuring that our clients receive the most accurate data possible.

Our laboratory adheres strictly to ISO 11885 standards during every step of the testing process, from sample preparation through analysis and reporting. This ensures that all results are reliable and can be trusted for decision-making purposes. By using this method, we provide our clients with comprehensive insights into potential risks associated with heavy metal contamination in their products.

In addition to compliance with ISO standards, our team of experts also follows other relevant international guidelines like those from the Food and Agriculture Organization (FAO) and World Health Organization (WHO), ensuring that all testing aligns with global best practices. This approach helps ensure that your organization remains compliant not only with local regulations but also meets international standards.

Understanding the importance of this service, we offer detailed reports for every sample tested, providing a clear breakdown of each metal detected along with its concentration level in parts per million (ppm). These reports are invaluable tools for maintaining product quality and ensuring consumer safety.

At [Your Laboratory Name], our commitment to excellence extends beyond just performing these tests; we also support your efforts by offering consultation services on how best to interpret the results obtained from this analysis. Whether you're dealing with raw materials or finished products, our team can guide you through the process of ensuring that your food and feed meet all necessary requirements.

Frequently Asked Questions

What does ISO 11885 ensure in terms of heavy metal analysis?

ISO 11885 ensures accurate and precise measurement of multiple metals including lead, cadmium, mercury, and arsenic in food samples using ICP-OES. This standard guarantees reliable data for quality control and compliance purposes.

How long does the testing process typically take?

The entire process usually takes about three working days from sample receipt to final report generation. However, this can vary depending on the complexity of the sample and the specific requirements outlined by the client.

Can you analyze all types of food products?

Yes, we can analyze a wide range of food products including grains, fruits, vegetables, dairy products, meat, and processed foods. Each sample type requires careful preparation to ensure accurate results.

What kind of equipment is used for this analysis?

We use state-of-the-art Inductively Coupled Plasma-Optical Emission Spectrometers (ICP-OES) that adhere strictly to ISO 11885 standards. These instruments provide high sensitivity and resolution necessary for detecting even minute concentrations of heavy metals.

Is this test suitable for both raw materials and final products?

Absolutely! Whether you need to check the quality of your raw ingredients before processing or ensure that your finished goods meet safety standards, our ISO 11885-compliant testing can help.

Do we need to do anything special with our samples before sending them?

Yes, please follow the detailed instructions provided in the sample submission form. Typically, this involves preparing your samples according to ISO 11885 guidelines by digesting them in a specific mixture of acids.

What if my product contains very low levels of heavy metals?

Our ICP-OES equipment is capable of detecting extremely low concentrations down to parts per billion (ppb), ensuring that even trace amounts do not go unnoticed.

How will the results impact my business?

Knowing exactly what heavy metals are present in your products allows you to take proactive steps towards maintaining product safety and meeting regulatory requirements. It also helps build trust with consumers who value transparency regarding ingredient quality.
