Abstract
Devices for chemical analysis include a first separation element formed on the substrate, the first separation element having a wicking surface that separates water from hydrocarbons in a fluid sample, a hydrophobic barrier at least partially surrounding the first separation element, a second separation element fluidically connected the first separation element, the second separation element configured to trap salts and organic matter present in the fluid sample, and a detection element fluidically connected to the second separation element, the detection element having a surface that binds with one or more analytes that may be present in the fluid sample and thereby emits a signal that is capable of being optically detected by a detector. Methods include providing such a device for chemical analysis, placing the fluid sample on the first separation element, and detecting the signal emitted by the detection element.
