## Abstract

Portable analytical equipment, systems, methods, and techniques related thereto is disclosed. Portable analytical equipment can comprise a controller and a probe. The probe can interrogate a sample and receive a response to the interrogation. The controller can select and/or initiate an analysis related to interrogating the sample via the probe. The analysis can be selected from a portfolio of analyses stored on the controller. The controller can analyze the response to the interrogation based on reference data stored on the controller. The controller can determine an indication based on the analyzing the response for presentation via a low-power interface, which can comprise an LED or electrophoretic element. The controller can further be connected to an external device, e.g., a smartphone or remote PC, to present collected data and the analyzing of the response to the interrogation. The disclosed subject matter can be employed in hand-held analytical equipment, e.g., a hand-held Raman spectrometer.
