| Abstract: Apparatuses and methods for in situ detection of a trace amount of an
analyte are disclosed herein. In a general embodiment, the present
disclosure provides a surface-enhanced Raman spectroscopy (SERS) insert
including a passageway therethrough, where the passageway has a SERS
surface positioned therein. The SERS surface is configured to adsorb
molecules of an analyte of interest. A concentrated sample is caused to
flow over the SERS surface. The SERS insert is then provided to a
portable Raman spectroscopy system, where it is analyzed for the analyte
of interest. |
