Industry partner delivering innovative and sustainable chemical solutions

For more than 25 years, Certech has been developing versatile analysis methods for liquid chromatography including HPLC (High Performance Liquid Chromatography) and GPC/SEC (Gel Permeation Chromatography/Size Exclusion Chromatography).

Analyses can be performed in a wide range of solvents; from non-polar organic to aqueous applications, at room temperature up to 220°C, with a complete set of columns.
A full range of detectors is available such as :
– Fourier Transform Infrared (FT-IR)
– UltraViolet (UV)
– Mass Spectrometer (QTOF)
– DRI (Differential Refractive Index)
– Light Scattering
– Viscometer
– ELS (Evaporative Light Scattering)

Key expertise includes:
-Information on polymer molecular weight distributions: Mn, Mw and Mz, polydispersity index (PDI), Mark-Houwink parameters
-Chemical composition analysis: identification and quantification of additives, oligomers, NIAS (Non Intentionally Added Substances such as degradation products) in very low concentrations, information related to chain branching, recycled polymers
-Microstructural characterization: information of the architecture coupling Temperature Rising Elution Fractionation (TREF) and preparative GPC and/or HPLC, Gradient Elution Fractionation (GEF), Hydrodynamic chromatography (HDC)

Certech’s technology platform allows the complete characterization of materials (chemical, physical, mechanical, and sensory properties).

Certech is an authorized Partner Laboratory of Agilent Technologies for its expertise in chromatography: GPC, TREF, TD-GC-MS
