Resources Hint 55.6% Enment Score: on 16 of 21 > A microfluidic device consists of microchannels etched into a glass chip. The liquid sample is then moved through the channels using electroosmosis. A particular microfluidic device contains a channel with a rectangular cross section of 15.5 um x 58.5 um. If a 159 pL sample is injected onto the channel, what is the length of the sample zone in millimeters? mm length: The sample travels the 29.7 mm to the detector in 7.09 s. Calculate the standard deviation of the bandwidth due to the finite size of the injection zone (m. On Calculate the standard deviation of the bandwidth due to diffusion (if the diffusion coefficient of the solute is 3.26 x 10ml = What is the total bandwidth at the baseline (w) if w = 40, where he is the observed total standard deviation of the bandwidth
