In this short communication, a low cost and easily feasible pressure-controlled extension of the previously described simple gradient liquid chromatography platform is proposed. A test mixture of four nitro esters was separated by 10-60%v/v acetone/water gradient and a high repeatability of retention volumes at 20 MPa (RSD less than 0.45%) was realized. Separations were also performed at different values of pressure (20, 25, and 31 MPa), and only small variations of the retention volumes (up to 0.8%) were observed. In this particular case, the gain in the analysis speed of 7% compared to the constant flow mode was realized at a constant pressure.
