What SEDERE does

SEDERE SAS is a privately held French scientific instrument company founded in 1989 and headquartered in Alfortville, France, with operational offices in Olivet. The company specializes exclusively in the design, manufacture, and commercialization of Low-Temperature Evaporative Light-Scattering Detectors (LT-ELSD) used in analytical and preparative chromatography. Its product portfolio comprises four analytical-grade detectors (SEDEX 81LT, 86LT, 100LT), a preparative-scale detector (SEDEX FP), a polymer-dedicated detector (SEDEX PA), and a suite of native PC drivers (SEDEX Drivers) that integrate its instruments with major chromatography data systems including Agilent OpenLAB, ChemStation, EZChrom, and Thermo Fisher Chromeleon 7.x. The technology platform rests on proprietary Gas Supported Focusing (GSF™) optics, low-temperature evaporation that protects thermolabile analytes, and the SAGA automated gain control system, with the SEDEX 86LT (launched 2026) representing the current mid-tier flagship featuring baseline noise of approximately 0.05 mV.

The company serves chromatography laboratories worldwide across pharmaceutical R&D and quality control, food and beverage testing (including authentication and adulterant detection), academic and polymer research, and general chemical analysis. Its go-to-market combines direct enterprise field sales with a global authorized distributor network and an active presence at major industry events such as Analytica and Ilmac. SEDERE's marketing is anchored on an extensive library of application notes and the SEDERE ELSD Bibliography, supporting top-of-funnel education, with direct contact and phone support handling bottom-of-funnel conversion. Pricing is not publicly disclosed; the product mix is predominantly one-time hardware sales of mid- to high-ASP scientific instruments, with a complementary software/driver layer and potential aftermarket services and accessories.

SEDERE is a small, family-run organization (11–50 employees, stated capital of €1,000,000) with no external equity funding, no M&A activity, and no public listing. Strategic activity in the most recent period is concentrated in product line renewal — the 2026 launch of the SEDEX 86LT, a refreshed corporate visual identity, and continued CDS integration — rather than in capital-raising or inorganic moves. The company is recognized in the industry as one of the historical pioneers and leading specialists in evaporative light-scattering detection, and it markets itself as the only vendor focused exclusively on chromatography detector development.
