Meeting the challenges of method development and validation in the laboratory

Bringing a product to market or evolving an industrial process requires rigorous analytical oversight. An unsuitable method can lead to unusable results, development delays, additional investigations, or difficulties during regulatory inspections. The challenge is therefore to have a reliable, sensitive method that is specific to the matrix being studied and suited to its intended use: assay, impurity identification, residue testing, material characterization, or process monitoring. In this context, analytical optimization and method development and validation help secure technical decisions at every stage of the product life cycle.

Develop a method tailored to your matrix and analytical objective

Method development consists of building an analytical strategy that is consistent with the nature of the product, the analytes sought, the expected levels, and regulatory constraints. The laboratory works on a wide range of issues: elemental impurity testing according to ICH Q3D, cleaning residue quantification according to ISO 19227, surface characterization by XPS, TOF-SIMS, or SEM, validation of chemical treatment processes such as passivation or anodizing, analysis of metal alloys such as TA6V, Cr/Co, or stainless steel, and characterization of HAP powders according to NF ISO 13779-3. This tailor-made approach makes it possible to obtain a method that is relevant, usable, and transferable.

Use instrumental techniques suited to the analytes and matrices

The choice of instrumentation is crucial to the success of a method development and validation project. Depending on the objectives, the laboratory uses liquid chromatography, ICP-MS, ICP-MS/MS, ICP-AES, and advanced physico-chemical characterization tools. These resources make it possible, for example, to identify and quantify elemental impurities, look for metal traces, assess organic or inorganic residues, control particulate contaminants, or characterize surfaces and materials. For morphological and surface characterization needs, also discover our expertise in SEM analysis.

Benefit from end-to-end support from development through to transfer

Entrusting your project to Filab means benefiting from continuous support from the definition of the need through to routine implementation. The laboratory handles development trials, parameter adjustment, validation, method transfer between the sending laboratory and the receiving laboratory, as well as the associated training. This continuity is particularly useful for R&D projects, process optimization, regulatory compliance, or investigations following non-conformities. For projects related to extractions in the context of biocompatibility, also see our page on ISO 10993-12 extraction method validation.

Rely on an expert laboratory to optimize, validate, and transfer your methods

The laboratory supports manufacturers from feasibility studies through to method transfer on site. This approach covers analytical development, pre-validation, validation in line with applicable standards, performance monitoring, and optimization when the matrix, process, or specifications change. This support is aimed at the pharmaceutical, cosmetics, biopharma, chemical, medical device, and materials sectors. To learn more about the stages in a method life cycle, see our page on laboratory purification method development and our content dedicated to analytical method validation.

Validate the method in line with regulatory and standards requirements

Validation demonstrates that the method is fit for its intended use with documented performance. Depending on the need, it can be carried out with reference to ICH Q2, USP 233, ISO 19227, ISO 10993, or other sector-specific texts. The characteristics assessed may include specificity, linearity, accuracy, precision, trueness, limits of detection and quantification, as well as robustness. For applications related to cleaning residues, also see our dedicated page on method validation according to ISO 19227.

Combine human expertise, state-of-the-art equipment, and a quality framework

Beyond the equipment itself, reliability depends on a structured quality organization, sector-specific expertise, and procedures adapted to industrial requirements. The laboratory relies on ISO 17025 accreditation issued by COFRAC for part of its activities, as well as experience in regulated environments. The standards used may include ICH Q2, ICH Q3D, USP, the European Pharmacopoeia, ISO 19227, ISO 10993, and other technical guides depending on the project.

Accelerate your industrial projects with FILAB, an independent and responsive partner laboratory

Filab operates as an independent laboratory, with a strong culture of analytical evidence and adaptation to client constraints. Manufacturers are looking for a partner capable of reducing lead times, securing data, and proposing tailor-made solutions for complex matrices. Its expertise covers in particular pharmaceutical and cosmetic products, medical devices, metal materials, treatment baths, raw materials, and formulations. This versatility makes it possible to integrate analytical optimization into a concrete approach to industrial performance.

Launch your project with a clear, actionable technical framework

To get started effectively, it is necessary to define the matrix, target analytes, expected thresholds, regulatory context, sample volume, and timeline. Based on these elements, a study plan can be established to develop, optimize, validate, or transfer the method under controlled conditions. Follow-up can then be extended through control charts, performance checks, and adjustments if the process or product changes. Contact Filab to define the need, frame the tests, validate the analytical strategy, transfer the method, and train the teams.
