Spectroscopies

The spectrometer that is available at ICSM is a SPECTRO ARCOS ICP Spectrometer (AMETEK Materials Analysis). This apparatus allows for the quantitative analysis of cations in liquids, with a detection limit of a few ppm.

ICP-MS ThermoScientific iCAP RQ

A Shimadzu UV-3600 UV spectrometer of the UV-vis-NIR type, covering a wavelength range from 190 to 3300 nm and equipped with:

• a double monochromator allowing a very high resolution (up to 0.1 nm) and a very low parasitic light (up to 5×10^-5 % at 340 nm),
• a tungsten source for VIS-NIR and Deuterium (D₂) for UV,
• a triple detector: PMT (photomultiplier tube) for ultraviolet and visible light, InGaAs and cooled PbS for near infrared light, allowing a noise level < 3×10^-5 Abs,
• a double beam.

ICSM is also equipped with two other spectrometers:

• a Thermo-Fisher UV spectrometer,
• a UV-vis spectrometer: VARIAN, Cary 50.

Perkin Elmer 's IR-FT100 spectrometer equipped with:

• a globar MIR source,
• a Fourier transform optical system with CsI separator and DTGS detector for a spectral resolution of up to 0.5 cm^-1.

It is also composed of three modules:

• for measuring diffuse or total reflectance and transmittance of solids (powders or thin films) using a PIKE integration sphere module, type MID Integratir, equipped with a cooled MCT detector, over a range of interest from 4000 to 650 cm^-1. Dedicated to specific research analyses,
• ATR-type measurement (Attenuated Total Reflection), thanks to a Perkin Elmer module made up of a diamond having 1 reflection of diameter 2mm set in a crystal of type condenser micro focus in KRS-5, allowing to access a wide range of waves number (10000 to 400 cm^-1). This module allows the rapid and unprepared routine analysis of raw solid, powder and liquid samples,
• measurement in transmission (KBr tablets, liquids).

Bruker's Vertex 70 IR spectrometer.

A Raman Horiba Jobin Yvon Labram Aramis spectrometer with the following specifications:

• 2 laser wavelengths, red (l = 633 nm), ~17mW and green (l = 532 nm), ~50mW,
• Objectives X10, X50 (LWD), X100 (LWD), confocal microscope with an axial resolution in optimal condition: < 2 µm and a spot diameter < 1 mm laterally,
• Spectral resolution in optimal condition: 0.5 cm^-1,
• Low frequency measurements <100 cm^-1,
• Possibility to work in a heating cell and in a controlled atmosphere (Linkam plate),
• Possibility to do mappings,
• Non-destructive measurement of powders, liquids, thin films.
