Microfluidic paper-based analytical devices are a technology that can be used to run reactions in order to test for certain analytes. These devices have extensive fibrous networks that make it possible for reagents to be dropped without spreading across the entire paper due to the wax barriers designed within the devices. Microfluidic paper-based devices have many advantages such as fast experimental time, versatility, low cost, and portability. For the detection of chloride, researchers have previously developed a distance-based paper analytical device. The development of this device stems from the importance of chloride detection in environmental and food analysis. In order to expand on previous research, we are attempting to determine the range of bottled drink samples that can be analyzed and we are working to expand the types of analytes that can be measured (carbonate and sulfate). Additionally, we are experimenting with polymer to observe whether or not the reagents used in the paper devices can be made stable over a longer period.
