Detection of trace amounts of perchlorate using SERS-active capture matrices
A perchlorate detector comprising: surface-enhanced Raman spectroscopy (SERS)-active, magnetic, capture matrices that are selective for perchlorate, wherein the capture matrices are designed to be added to a sample solution; a detection chamber configured to hold the sample solution and the capture...

| description | A perchlorate detector comprising: surface-enhanced Raman spectroscopy (SERS)-active, magnetic, capture matrices that are selective for perchlorate, wherein the capture matrices are designed to be added to a sample solution; a detection chamber configured to hold the sample solution and the capture matrices; a selectively engageable magnet assembly coupled to the detection chamber such that when the magnet assembly is engaged or disengaged the capture matrices are respectively confined or not confined to a confinement region of the detection chamber; and a Raman spectrometer optically aligned with the confinement region of the detection chamber and configured to interrogate the capture matrices when the magnet assembly is engaged in order to detect and determine a concentration of perchlorate bound to the capture matrices. |
