  Method of using a sensor array for simultaneously determining a partition coefficient and a diffusion coefficient of analytes. At least two sensors comprising the same polymer composition, but with differing predetermined polymer thicknesses, are used to measure the time lag difference between the sensors. This measurement is used to determine both equilibrium or steady state parameters as well as kinetic or diffusion coefficient information. The steady-state data can be used for analyte determination, whereas the kinetic data can be used for sensor array optimization and design.

  使用传感器阵列同时测定分析物的分配系数和扩散系数的方法。至少两个传感器由相同的聚合物组成，但具有不同的预定聚合物厚度，用于测量传感器之间的时滞差。这种测量可用于确定平衡或稳态参数以及动力学或扩散系数信息。稳态数据可用于分析测定，而动力学数据则可用于传感器阵列的优化和设计。

  Methods and systems are for determining the concentration of a chemical species in an analyte solution. At least one train of segments are injected into a microfluidic channel having a first end and a second end, each train of segments having segments of analyte solution and segments of sensing solution which are immiscible with the segments of analyte solution. The train of segments is circulated from the first end to the second end of the microfluidic channel such that a reversible chemical exchange is established between the chemical species of each segment of analyte solution and a chemical indicator of the at least one contacting segment of sensing solution. The response of the chemical indicator is measured at the second end of the microfluidic channel and the concentration of the chemical species in the analyte solution is determined based on the response.

  An automated, fieldable ion-selective sensor system for frequent detection of nutrients in soils or water is set forth. In one aspect, an integrated small form-factor housing includes a battery, processor, a fluid manipulation unit and reservoirs, and a chemical species detection cell. A flow-through sampling head can be connected to the detection cell and a waste reservoir by flexible tubing sealingly connected at opposite ends of the tube. In one aspect, improved performance of the ion-selective sensor includes adding an ion-to-electron transfer interlayer between an ion-selective membrane and its working electrode. In one aspect, the sensor is solid-state and uses printed polymeric composite of POT-MoS2. The use of a porous tube for a sampling head and fluid connection at opposite ends allows not only fluid to be removed from the head to the detection cell for measurement but also flow in an opposite direction and out to a waste reservoir to clean and reset for a next sample measurement.
