Title: FLUID FLOW CELL INCLUDING A SPHERICAL LENS
Abstract:
A flow cell device including a spherical optical element is disclosed. The spherical lens can be sealed to the body of the flow cell device in a manner that provides external optical access to a fluid in an analysis region of a flow path through the flow cell device. The seal can be provided by an elastomer, a polymer, or a deformable metal. The disposition of the spherical lens to the flow path enables in situ optical analysis of the fluid. An optical analysis device can be removably connected to the flow cell device to provide the optical analysis. In some embodiments the optical analysis device is a portable Raman spectrometer. The flow cell device can provide a supplementary interrogation interface, and/or an on board sensor device(s) to enable multivariate analysis and/or advanced triggering.
