    Our strengths and services<\/h2>\n\n\n\n

    A wide range of equipment<\/strong>We have a wide range of equipment for chromatography, spectrometry, extraction and characterization of compounds of interest. This equipment delivers precise, reliable results which are essential for quality research.<\/p>\n\n\n\n

    Advanced technologies<\/strong>We use various technologies such as liquid and gas chromatography, mass spectrometry and advanced extraction tools. Among these technologies, SIFT-MS (Selected Ion Flow Tube Mass Spectrometry) stands out for its ability to quantify low-concentration volatile compounds in the gas phase in real time, offering rapid, non-destructive results.<\/p>\n\n\n\n

    Equipment<\/strong>– Chromatography and Spectrometry: Our equipment includes HPLCs coupled with various types of detection, GC-FID, GC-MS and SIFT-MS systems for fast, accurate analysis. SIFT-MS is particularly advantageous for quantifying volatile compounds in the gas phase, thanks to its sensitivity and speed of analysis.<\/p>\n\n\n\n

    – Extraction and Characterization: We offer accelerated solvent extraction, elemental analysis and particle characterization services. Our tools include pressure extractors, spectrophotometers and combustion nitrogen analyzers.\u00a0<\/p>\n\n\n\n

    – Sample preparation: We have specialized equipment for sample preparation, such as evaporators, freeze-dryers, filtration systems and centrifuges. These tools enable samples to be prepared efficiently and reproducibly for subsequent analysis.\u00a0<\/p>\n<\/div>\n<\/div>\n<\/div><\/div><\/div><\/div><\/div>\n\n
