that require a narrow particle size distribution, such as for the calibration of analytical instruments. To address this shortcoming associated with the emulsion polymerization process, adaptations can be incorporated that result in a narrower particle size distribution, e.g. applying seed methods [96]...

This new set expands the Starna range of polystyrene film references for use in FTIR, MidIR and NIR Wavelength Calibration to include both Transmission and ATR modes. Existing films are available in two thicknesses: RM-1921/38 is a 38 µm polystyrene film with 14...
A Waters 2410 refractive-index detector (λ 1/4 930 nm) with a PS calibration was used. Scanning electron microscopy (SEM) of the membranes was carried out on a LEO Gemini 1550 VP (Zeiss, Oberkochen, Germany) at a voltage of 3 or 5 kV. The samples were coated with 2.0 nm platinum....
