# Raw material purity analysis laboratory

## Your needs: carry out a purity analysis on raw materials

### Chemical purity analysis

The purity of a product in chemistry refers to the degree to which a substance consists exclusively of the desired molecule or chemical element, without contamination by other substances. Purity is an essential measure for determining the quality and effectiveness of a chemical compound.

### When should you call a purity analysis laboratory?

In the event of a visual [failure](https://filab.fr/en/our-services/our-expertise-services/laboratory-analysis-failures.md), altered solidity, or the appearance of an unknown substance, a purity check allows you to:

- Quickly identify the source of the anomaly.
- Determine whether the offending raw material or batch should be removed or corrected.
- Secure the production line by avoiding costly non-conformities.

### Why carry out a purity analysis of your products?

The “purity” of a material or raw material will make a major contribution to optimising its final performance. Regular checks on materials are therefore an essential stage in the production process.

In the event of a [fault](https://filab.fr/en/our-services/our-expertise-services/laboratory-analysis-failures.md) (visual defect, questionable solidity, appearance of an unknown substance, etc.), manufacturers from all sectors regularly call on analysis laboratories to check the purity of their raw materials or materials used.

### Determining the purity of a substance

Determining the purity of a substance involves analysing its components to check its chemical composition and identify any impurities or contaminants. This process is essential in many industrial sectors, such as [pharmaceuticals](https://filab.fr/en/sectors-of-activity/analysis-industry-pharmaceuticals.md), [cosmetics](https://filab.fr/en/sectors-of-activity/laboratory-analysis-cosmetics.md)and [metallurgy](https://filab.fr/en/sectors-of-activity/laboratory-metallurgy-steelmaking-analysis.md), to ensure that the substance complies with quality and safety standards.

### Carry out chemical purity and trace element analysis

**Chemical purity analysis** is essential to ensure that your materials are free from contaminants. The presence of trace elements, even at extremely low concentrations, can have a significant impact on the quality, performance or safety of your products.

[Trace element analysis](https://filab.fr/en/our-services/our-expertise-services/laboratory-analysis-failures/laboratory-analysis-trace-chemicals.md) can [detect and quantify these impurities](https://filab.fr/en/our-services/our-analysis-services/laboratory-detection-identification-impurities.md) present in your materials. Advanced techniques such as inductively coupled plasma mass spectrometry (ICP-MS) are commonly used to identify heavy metals, toxic substances or non-compliant elements.

This ensures the quality of components used in demanding sectors such as aeronautics and automotive. Purity testing helps optimize material performance while meeting international standards.

 What types of contaminants can be detected during a purity analysis of medical devices?
Purity testing of medical devices detects chemical, particulate, or microbiological contaminants that could affect the product's biocompatibility. The techniques used, such as electron microscopy and ICP-MS, comply with ISO 10993-18 and ISO 19227 standards and ensure that devices are free from harmful substances that could compromise patient health.

 How does purity analysis help meet environmental standards in the chemical industry?
Purity analysis is essential in the chemical industry to detect traces of pollutants or toxic elements in products or waste. Purity analyses ensure that chemical products comply with environmental regulations, such as the REACH directive in Europe, by preventing the release of hazardous substances into the environment.

 How important is material purity in the electronics industry?
In the electronics industry, material purity is important to prevent component failure. Even trace levels of impurities can impair the performance of semiconductors and other sensitive components. Purity analysis, particularly using ICP-MS and ion chromatography, helps ensure the quality of materials used and the reliability of finished products.
