instrumentation provides partial results only, also based on the interaction of the investigated material with a probing medium [1].

For multiple materials & coatings, obtaining elemental and molecular information for different probing size and depth is especially crucial. HORIBA offers a Platform with multiple instruments that could be coupled permitting to tackle complex analytical challenges.

Glow Discharge Optical Emission (GD) relies on a plasma to sputter a representative area of a material and provides fast elemental depth profile with nanometer resolution [2]. GD has already been used to prepare samples for SEM and has been coupled with XPS and HAXPES.

Coupling GD and Raman Microscopy is very interesting to simultaneously obtain both the elemental profiles and molecular information at various depths with high lateral resolution [3,4].

Similarly mapping a surface with both µ XRF and µ Raman will offer spatially resolved elemental and molecular information of a material and could be used also for example to provide full identification of particles deposited on a substrate.

Coupling an ICP instrument to an electrochemical cell (AESEC technique) transforms a technique dedicated to the compositional analysis of liquids (ICP) into a tool for corrosion studies of metals and alloys offering deep insight into dissolution mechanisms and surfaces reactivity [5].

An other coupling - ICP with ETV – Electrothermal Vaporisation offers direct measurement of solids by ICP - for example to study battery Carbon purity [6].

We will illustrate the benefit of this Platform for Elemental and Molecular Analysis by showing selected results on metallic parts for high temperature fuel cells, catalysts coated PEM membranes, fuel facing materials in Na fast reactors, perovskite solar cells, hydratation of anodic films, batteries and DLC coatings on bipolar plates.
