| 520 | _ | _ | |a Thermophoresis, the migration of particles within a thermal gradient, presents opportunities in diverse fields ranging from biotechnology to energy applications. The quantification of this phenomenon, described by the Soret coefficient (S_T), requires precise control over non-isothermal conditions, which is challenging to achieve in conventional microfluidic devices. However, conventional polymer-based cells are limited by a significant temperature drop across the material and susceptibility to the adhesion of colloidal particles. Recently, 3D-manufactured glass cells have been shown to produce a non-isothermal temperature field in a microchannel for inducing a significant temperature gradient due to high thermal conductivity, which enables temperature-dependent analysis of thermophoresis. Herein, we present a 3D-manufactured glass microfluidic cell for measuring the Soret coefficient under controlled temperature gradients. The cell produces a stable and a large temperature gradient across the channel which allows multi-temperature measurements without adjusting hot and cold water temperatures. The measured Soret coefficient by the glass cell across a temperature range of 20 °C to 30 °C shows close agreement with the benchmark measurement data. These results show that the 3D-manufactured glass cell can not only quantify the Soret coefficient but can also function as a solvent-resistant device, suitable for complex biological and chemical solutions. |
