Capillary hydrodynamic fractionation of hydrophobic colloids: Errors in the estimated particle size distribution

- Three error sources were investigated in estimating particle size distribution by CHDF.
- Small error in diameter calibration can produce large deviation in the estimated average diameter.
- Error in particle refractive index can affect the estimated mode number concentration.
- Instrumental broadening correction can produce PSDs with underestimated width and distorted shape.
- Simulated and experimental examples were used to quantify the errors.
