Table 2. Comparison of the experimental parameters for both capillaries.

Q: total volume flow rate; v: linear flow speed; t _dwell: average dwell time in the X-ray beam; Re: Reynolds number (for water); N _SAXS: number of SAXS curves taken; t _tot: total exposure time of the sample. Due to the smaller diameter of the d _i = 0.9 mm capillary, the flow speeds for equivalent flow rate are higher and the average dwell times shorter.
