Electron Microscopy Platform of Lille (PMEL)

Platform

Description

PMEL platform is a national electron microscopy center dedicated to the characterization of materials (metals, glasses, ceramics, polymers, minerals) with an expertise in quantitative nano-analysis and electron diffraction. Using our state-of-the-art equipment (transmission electron microscopes, scanning electron microscopes, electron microprobe, sample preparation equipment), we can describe the microstructures and chemical compositions of nanoscale and subnanoscale samples and perform spectroscopic studies of valence states, physico-chemical environments of atoms and ab-initio analyses of structures. We also perform fine compositional quantification studies for minor elements and chemical mapping. We are open to all academic and industrial collaborations and propose services in line with our expertise.

Equipments

The PMEL platform is equipped with two transmission electron microscopes (aThermo Fischer Titan Themis 60-300kV and a Thermo Fischer Tecnai 200 kV), three scanning electron microscopes (including a Jeol low pressure SEM, a HITACHI SU 5000 analytical variable pressure SEM and a Hitachi tabletop SEM) and an electronic microprobe (CAMECA SX 100). A set of sample preparation equipment is also available, including microtomes or ultra-microtomes (cryo), a semi-automatic mechanical polishing system, and precision thinning and ion polishing machines.
