Laboratoire de caractérisation des matériaux polymères (LCMP)

The Laboratory brings together an advanced platform in the field of polymer materials. The LCMP facilities include several calorimetric techniques (DSC, TGA and ITC), size exclusion chromatography and light scattering, zeta potential, andX-ray (SAXS). In LCMP, all external reports are signed by a member of the Ordre des Chimistes du Québec.

Chromatography

Size Exclusion Chromatography

Analyses can be performed in water, tetrahydrofuran (THF), chloroform (CHCl3) and dimethylformamide (DMF).

Analysis via a calibration curve

 

Relative molar masses Mn, Mw and Mz relative, and polydispersity

Several standards available depending upon solvent (mobile phase)

 

 

Multiangle light scattering detector

  

Absolute molar masses Mn, Mw and Mz (without calibration curve) and polydispersity index. dn/dc must be know

Radius of gyration (Rg) can be obtained

 

 

Triple detection analysis

 

Analysis can be made carried out via a standard calibration curve, by universal calibration or by  light scattering

The combination of the three detections allows a better accuracy on the calculated molecular weights

 

 

Determination of particle size

Malvern Zetasizer systems

- Dynamic light scattering (DLS)

- Particle size, Rh, from 1 nm up to 6 um per sample

- Analysis in aqueous medium and organic solvent

- Zéta potential analysis

 

 

Brookhaven BI-200SM system

Dynamic and static light scattering (batch mode)

Mw, Rg and A2 available from the Zimm plot

Rh available at with several angles (for asymmetric particles)

 

 

Horiba LA-950 laser particle size analysis

Static light scattering with Mie diffusion

Range between 10 nm and 3 mm

Analysis in aqueous medium or in dry conditions

 

 

Calorimetric analysis

Calorimetric analysis

Differential scanning calorimetry (DSC)

Differential scanning calorimetry (DSC) allows the determination of phase transitions :

·        Glass transition temperatures (Tg) of polymers, metallic glasses and ionic liquids

·         Melting (Tm) and crystallization (Tc) temperatures

·         Enthalpies of reaction, degree of crosslinking determination of a polymer

LCMP is equipped with 2 high-performance DSC  -TA DSC Q2000.

 

Features

·         Very flat baseline

·         Temperature range from -94 to 400°C for scanning rate up to 200°C / min

·         Autosampler (50 positions)

·         PhotoDSC: in situ crosslinking reactions in the DSC

·         Modulated DSC to separate reversible (thermodynamics) and irreversible events (kinetic)

To avoid sample degradation or spills in the DSC, TGA measurement is mandatory for any new set of samples.

Thermogravimetric analysis (TGA)

Thermogravimetric analysis (TGA) measures the decrease in mass of a sample as a function of time for a given temperature or a temperature profile.

 

The TGA is usually used for:

  • Degradation temperatures determination,
  • Percentage (%) of solvent or moisture residues absorbed or crystallised in the material,
  • Proportion of organic to inorganic material,
  • Estimation of the oxidation kinetics at high temperature,
  • Thermal stability profile of a compound in a non-oxidizing gas.

 

Performance characteristics of the TGA:

 

  • Experimental temperature range from ambient to 1000°C.
  • Vector gases: nitrogen, air or argon.
  • High resolution and sensitivity module available.
  • Scanning rate from of 0.1 to 100 ° C / min

 

 

Isothermal titration calorimetry (ITC)

L'ITIsothermal titration calorimetry (ITC) is used to determine the thermodynamic parameters of interactions in solution. It is most often used to study the binding of small molecules to macromolecules (proteins, DNA etc.).

 

  • Binding affinity
    • Affinity KD
    • Binding Heat - ΔH
    • Number of binding sites \ stoichiometry - N
  • Mechanism of binding
  • Rational drug design / SAR
  • Enzyme Kinetics

 

 

ITC MicroCal 200

 

  • Temperature range : 2-80 °C
  • Pulse titration of equal volumes or continuous injection titration
  • ITC 200: Cell of200 μl and syringe of 70 μl, injection volume of 40 μl, stirring speed: 750 rpm, temperature stability of 1.5 x 10-4 °C
  • VP-ITC:  Cell of 1400 μl, injection volume of 300 μl, and stirring speed: 800 rpm

 

 

SAXS

NANOSTAR with 2D detector                   GiSAXS

 

 

 

 

 

 

 

SAXS allows the determination of the lamellar organization of materials.

In GISAXS for condensed materials, it is possible to determine the organization of a thin layer of material deposited on substrates.

 

             Four sample detector -  Distances (D) are available from SAXS to WAXS: 107, 68, 28, 13 cm.
