Full textIn capillary electrophoresis, reproducibility depends essentially on the maintenance of the signal and the migration time when the analysis of the same sample is repeated. Variations in the electroosmotic flow (EOF) between runs are one of the major factors affecting these parameters. In this work, a new approach to monitor the EOF based on thermal marks (TMs) is proposed. TM consists in a signal present in the electropherogram caused by heating (typically 100 ms) a small portion of the capillary (approximately 1 mm), while the electric field is applied. The most effective device to promote the heating was a 15-Ω SMD resistor, powered at 5 V. Studies about the origin of TMs suggest that the phenomenon is related to variations in the transport number of the species due to alterations in the temperature. This conclusion was based on comparison between the TM profile and the transport numbers values, as well as results from computer simulation. The proposed applications for TM include: correction in variations of migration times with alterations on EOF, EOF measurement and optimization of the parameters of contactless conductivity detection. Additionally, a new sample injection procedure, called thermal injection, was also proposed. The advantage of this injection consists in minimization of leakage problems related to the continuous introduction of the sample in the separation channel in microchip-CE. To perform the thermal injection, the capillary is completely filled with the sample diluted in a BGE and the injection occurs with the generation of a TM. Studies with NaCl solutions presented extensive linear response range from 10 µmol L-1 to 1 mmol L-1. However, interference problems on sensibility and analytes mobilities appeared. The use of low-concentration solutions diminishes these problems. However, the analytical signal is also diminished, needing a strategy to raise the sensitivity. Thus, a multiplexing technique based on a new algorithm was also introduced in order to improve signal-to-noise ratio. Although the efficiency of the mathematic modeling on the signals decoding, the desired improvement of signal/noise ratio was not obtained, because the analysis time would be excessively high. However, the employment of the thermal injection seems to be very suitable for multiplexing, due to the possibility of performing several sequential injections with no interruption of the electric field. Afterwards, the implementation of fast velocity devices to generate TMs would enable the technique. Finally, the great perspective to applications of TM concerns in the use of TMs to obtain physical chemical constants, such as pKa and ionic mobilities. The present work describes values of ionic mobilities calculated to monopropyl carbonate, monoisopropyl carbonate, and hydronium.

A flexible skin, on which an array of miniature thermal film sensors was situated, was successfully made with a MEMS fabrication process. The design was featured with using platinum as sensing material, deposited on polyimide layer as flexible substrates. In the process, only two masks were used for defining the patterns of the thermal sensors and conducting wires, respectively. The polyimide layers were deposited on top of a thin aluminum layer, which served as a sacrificial layer, hence the flexible skin could be released after metal etching and peeled off easily. The flexible skin together with thermal sensors is survived under large deformation, hence ideal for bonding to a highly curved surface. Each of the sensors shows the linear temperature-dependence characteristic, with the coefficient of resistance (TCR) of 0.247% /℃ was measured. By imposing a stepwise change of surrounding temperature to a sensor, the constant-current circuitry output showed a dynamic response up to 1.1 kHz. The thermal sensor was employed to measure the vortex shedding frequency behind a T-shaped cylinder, at Reynolds numbers 5.4×103—2.8×104. The spectral results reduced from the measured signals confirm that the measurement system was able to resolve the shedding frequency up to 55 Hz. Subsequently, experiments were made to detect the separation point on a circular cylinder normal to the incoming flow. The time-mean separation point on the circular cylinder surface reduced from the signals measured show a very good agreement with the results reported in the literature. Further, an array of thermal film sensors consisting of three sensors were employed to investigate the relation between low-frequency modulations and instantaneous vortex shedding frequency. The analysis was carried out using the wavelet analysis and a correlation technique. The results obtained successfully reveal the instantaneous characteristic behavior of unsteadiness of flow separation on the cylinder model.
