In this paper a method based on attenuated total reflection–Fourier-transform infrared spectroscopy is described to measure the concentration of colloidal particles dispersed in a liquid near a solid boundary in pressure driven flows. The method has been used to obtain measurements of wall depletion in an aqueous suspension of ethylcellulose particles. The method is capable of measuring the particle concentration in a thin layer near the boundary, whose thickness is between 0.3 and 1.4 μm. A… 
Effects of particle size on near-wall depletion in mono-dispersed colloidal suspensions.
TLDR
It was found that wall depletion was not significant for Peclet numbers smaller than unity, and estimates of the wall slip layer thickness obtained from rheological experiments were consistent with the results obtained by ATR-IR spectroscopy.
Wall slip of concentrated suspension melts in capillary flows
Abstract The effects of wall slip of concentrated suspension melts in capillary flows were investigated at elevated temperature. The modeled material is a mixture of polymer EVA (Ethylene Vinyl
Non-isothermal analysis of concentrated suspension slip flow with particle migration
When a concentrated suspension is forced through the channels or tubes that are at a temperature different from that of the suspension, the suspension temperature and particle distribution change
Estimating depletion layer thickness in colloidal systems: Correlation with oil-in-water emulsion composition
Abstract In emulsions, slippage due to wall depletion effects is well known in rheological investigations. This effect can be overcome by using geometries with serrated surfaces. However, we present
A review on wall slip in high solid dispersions
High solid dispersions are soft materials made of colloidal or non-colloidal particles dispersed at high volume fractions in a liquid matrix. They include hard sphere glasses, colloidal pastes,
On the use of rough geometries in rheometry
Abstract Multiphase fluids, like suspensions, often show wall slip. This is induced by depletion of particle concentration in proximity of wall surfaces. The rheometrical data can be corrected for
