This disclosure provides a system component and method for analysis of airborne analytes by absorbing the analytes into a liquid and interrogating the liquid with an analytical instrument. In some examples, a cartridge with a microfluidic chip contains a vessel of a colloidal solution of nanostrutured particles in a liquid. The vessel is broken, releasing the solution into microfluidic containers on the chip. Air having analytes is passed over the chip leading to absorption of airborne analytes into the solution. The analytes bind with the nano structures and are detected optically. Techniques are disclosed for filling the vessel in a way that maintains the efficacy of the solution until it is needed for measurement.
