Abstract
A flow cell can comprise a high-pressure, fluidic, flow-through housing that encloses and auto-aligns a heavy-walled, internally reflective low-cost glass capillary for concentrating and amplifying laser-excited spectra. The containment housing that encloses the capillaries can optionally sustain operational pressures of at least 10,000 psi. The pressure housing can be fitted with transparent optical windows that can accommodate laser-safe injection and spectra collection. The flow-cell design can adaptably accommodate different optical sampling configurations such as transmissive (forward scattering), reflective (backward scattering), or multipass, combined scattering. The flow cell size is scalable (lengthwise) to accommodate different applications or installations such as benchtop (lab), permanent (industrial), and portable (field). With new, miniaturized spectrometers, the flow cell can optionally be configured for transport as a real-time, high-sensitivity gas-analysis sensor aboard compact aerial or otherwise mobile systems (e.g., drones) for remote or hazardous applications.
