Which laboratory supports non-conformity investigations?

A non-conformity can arise at different stages of a product’s lifecycle: receipt of raw materials, manufacturing, packaging, storage, market launch, or regulatory inspection. When a result deviates from the specifications, the challenge is to quickly assess the discrepancy, identify its root cause, and evaluate its impact on the product’s quality, safety, regulatory compliance, or performance. An independent laboratory such as the FILAB laboratory then provides decisive support to guide investigations, compare results with expectations, and produce reliable analytical data on a wide range of matrices: materials, treatment baths, process water, formulations, devices, packaging, or finished products.

An effective investigation starts with qualifying the issue: limit exceedance, presence of a contaminant, purity defect, composition anomaly, migration from packaging, leaching from a material, chemical instability, or performance deviation. From this finding, the analysis plan must prioritize hypotheses and define the useful tests: screening, confirmation, quantification, comparison with a compliant reference, surface study, deposit analysis, or impurity search. This approach saves time and focuses efforts on the likely causes of the non-conformity.

Investigations into non-conformity may require the search for and quantification of elemental impurities, heavy metals, regulated organic compounds, leachables, additives, process residues, or traces of contamination. Chromatographic and spectrometric techniques make it possible to work at trace levels on complex matrices and address issues of purity, regulatory compliance, stability, or quality disputes.

Working with an independent laboratory such as FILAB laboratory provides an external perspective, specialized analytical expertise, and already operational resources to quickly address an anomaly. This setup reduces mobilization times, secures data generation, and facilitates decision-making when the stakes are critical: batch hold, customer complaint, supplier dispute, regulatory investigation, or process optimization.

The laboratory FILAB supports manufacturers in defining the study plan, selecting analytical techniques, preparing samples, researching impurities, quantifying targeted compounds, characterizing contaminants, and interpreting results. The approach is tailored to the context of the observed deviation: process drift, metal contamination, container-content interaction, leachables, extractables, elemental impurities, volatile or semi-volatile substances, material defects, or stability issues. To learn more about the laboratory’s capabilities, you can consult laboratory.

Depending on the nature of the deviation, several methods can be combined: liquid chromatography, gas chromatography, ICP-AES, ICP-MS, ICP-MS/MS, ion chromatography, surface characterization techniques, and imaging. These tools make it possible, for example, to look for metallic traces, quantify volatile organic compounds, identify non-volatile substances, characterize particles, or assess material-product interactions.

When the deviation concerns a material, a deposit, an inclusion, a surface, or a localized defect, complementary characterization methods may be required. Surface observation and analysis help to understand corrosion, a particle, an appearance defect, or a material interaction. Depending on the need, it may be relevant to turn to a specialized laboratory for characterization or to a laboratory for structural analysis.

Beyond one-off analysis, support can cover the development of tailor-made analytical methods, their validation, method transfer, targeted literature reviews, stability and chemical compatibility studies, as well as the definition of a study plan adapted to your needs. This approach is particularly useful when the non-conformity concerns a complex matrix or a compound that is difficult to characterize.

To get started effectively, you should provide the context of the deviation, the specifications, the matrix description, the process history, the results already available and, if possible, compliant and non-compliant samples. The laboratory can then define a study plan, select the priority tests and carry out the most relevant analysis. For a related need concerning material defects, you can also consult our expertise in laboratory. Defining the need, providing the key information, having the samples analyzed, confirming the source of the deviation and obtaining technical support for decision-making: this is the approach to prioritize.
