Gas chromatography
With our flexible range of equipment available for performing gas chromatography (GC), we can offer a wide variety of tests for your raw materials, APIs and finished products. We use state-of-the-art gas chromatographs with liquid and headspace injection. Flame ionisation detection (FID) and mass spectrometric detection (GCMS) are currently available.
Common methods in our portfolio include:
- Residual solvent analysis in accordance with Ph. Eur. 2.4.24 or USP <467>
- Assay and / or purity testing
- Determination of fatty acid profiles in accordance with Ph. Eur. 2.4.22 or USP <401>
- Limit tests for ethylene oxide and dioxane in accordance with Ph. Eur. 2.4.25 or USP <228>
- Ethylene glycol and diethylene glycol in ethoxylated substances in accordance with Ph. Eur. 2.4.30
- Ethylene glycol, diethylene glycol and triethylene glycol in ethoxylated substances in accordance with USP <469>
If you require individual solutions, we are happy to assist you and offer:
- Method development for individual products or specific raw materials
- Method validation for individual products or specific raw materials
- Method transfer of existing, validated methods
- Analyses using MS detection, e.g. for the identification of unknown impurities, to support root cause analysis or to achieve low limits of detection.
