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 14.0 pm x 74.1 um. If a 149 pL sample is injected onto the channel, what is the length of the sample zone in millimeters? Number 0 The sample travels the 24.2 mm to the detector in 6.50 s. Calculate the standard deviation of the bandwidth due to the finite size of the injection zone. inj diff Number 0 Calculate the standard deviation of the bandwidth due to diffusion if the diffusion coefficient of the solute is 3.06 x 10 m/s. W= mm Number 0 What is the total bandwidth at the baseline (w), if w = 40obs, where Jobs is the observed total standard deviation of the bandwidth? Number
