Embodiments of the disclosed invention provide devices and methods for buffering sweat samples to enable accurate concentration measurements of sweat analytes by salinity - sensitive or pH- sensitive sensors. The buffering capabilities of the device include the ability to control the salinity and pH of a sweat sample, specifically, through the management of solutes in sweat such as salts, H+, other ions, and other sweat contents. The purpose of such control is to enhance particular sweat sensing device applications by improving detectability of the targeted analyte, or improving performance of analyte sensors. Some embodiments also include components to enable sample concentration to enhance the measurement of low- concentration sweat solutes. |
