Gel Permeation Chromatography (GPC)
GPC allows for the determination of number average molecular weight (Mn) and molecular weight distribution (PDI=Mw/Mn) of polymers. This Agilent GPC system with 1260 Infinity Multi-Detector has columns that can run in various solvents such as DMF, THF and DMS and is equipped with viscometer and refractive index detectors. Calibration can be performed with narrow molecular weight polyethylene oxide (PEO) and polystyrene (PS) standards.
UV-2600 UV-VIS Spectrophotometer
The compact UV-2600 is a universal, research-grade spectrophotometer that can be used in a wide range of fields.
TENSOR II FTIR Spectrometer (includes ATR attachment)
Dynamic Light Scattering (DLS)
Our DLS measures particle and molecule size from below a nanometer to several microns using dynamic light scattering. Particle size range from 0.3 nm to 10 µm can be detected over a temperature range of 2°C to 90°C.
Fluorescence correlation spectroscopy (FCS) and Fluorescence recovery after photobleaching (FRAP)
FCS allows measuring the diffusion coefficient of the polymer or polymer complex within solution. FCS is capable of detecting and distinguishing between single and multiple component diffusion. FRAP gives information about lateral diffusion within polymer films of orders up to 10-16 cm2/s.
