As a consequence the mixing effects are reduced in the case of methanol, because the expansion due to heating compensates for the contraction due to mixing, and are increased in the case of acetonitrile, where both mixing and cooling cause a reduction in volume.

In addition, acetonitrile/water mixes have lower viscosity than methanol/water mixes and therefore generate substantially lower back pressures across the LC column (Figure 1). This lower backpressure is often seen as advantageous as it puts less strain on the LC system components and column, and provides scope to increase flow rate and reduce run times.
