# Analysis of undesirable substances

## You wish to carry out an analysis of undesirable substances

In the context of regulatory non-compliance, process improvement or product [failure](https://filab.fr/en/our-services/our-expertise-services/laboratory-analysis-failures.md), manufacturers may be required to perform analysis of undesirable substances in an organic or inorganic matrix.

Even in trace amounts, certain elements such as metals ([lead](https://filab.fr/en/laboratory-analysis-lead/), mercury, cadmium, etc.) can constitute a danger for consumers. Subject to important regulatory constraints, the control of their presence is therefore essential.

The realization of these controls of substances requires precise tools, being able to go to the level of ppm to see ppb. Also, the support of a specialist laboratory will allow you to analyze your samples quickly and accurately.

## FILAB performs analysis of undesirable substances regardless of the type of matrix to be studied

FILAB, an independent laboratory located in Dijon, has been working for 30 years with industrial companies in all sectors in the analysis of undesirable substances. With a wide range of state-of-the-art analytical equipment (ICP, GCMS, IC, SEM, EDX, etc.), FILAB adapts its methods of analysis according to the matrix to be studied (liquid, solid, powders, etc.).

Here are the services we offer:
