# Preparative chromatography laboratory

## Your needs: have an impurity characterized by a preparative chromatography laboratory

### What is preparative chromatography?

Preparative chromatography is an advanced technique for separating and purifying a specific impurity in complex samples, ensuring in-depth analysis using state-of-the-art technology. Whether you need to comply with regulations, improve the quality of your products or optimise your processes, FILAB, an expert laboratory in preparative chromatography analysis, guarantees you reliable, usable results.

### Why use a laboratory with preparative chromatography?

**Preparative chromatography** is an essential technique for **isolating [impurities](https://filab.fr/en/our-services/our-analysis-services/laboratory-detection-identification-impurities.md)** present in a sample. Once these impurities have been isolated, it is possible to carry out in-depth and precise analyses, avoiding any interference. This process is essential for guaranteeing the purity of products in 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 [aeronautics](https://filab.fr/en/sectors-of-activity/laboratory-analysis-aeronautics-aerospace.md)…

### The advantages of preparative chromatography

- **Analytical Chemistry**: qualitative and quantitative analyses to study samples after purification.
- **Organic Chemistry**: precisely characterizing the structure and properties of isolated impurities

## FILAB, a preparative chromatography laboratory, can help you with your impurity characterization needs.

### Why choose FILAB?

FILAB, a laboratory specialising in preparative chromatography analysis, can help you analyse and characterize impurities in your samples. Thanks to a team of experts and [state-of-the-art analytical equipment](https://filab.fr/en/our-technical-resources.md), FILAB also offers other impurity analysis services:

## our complementary analysis services
