About

Nirrin Technologies builds analytical instruments that measure biopharmaceutical process fluids in real time. Its proprietary High-Precision Tunable Laser Spectroscopy (HPTLS) platform pairs near-infrared spectroscopy with a tunable laser source to quantify protein titer, buffers, excipients, glucose, lactate and cell density directly, without dilution or sample separation. The company sells benchtop and in-line systems used from upstream process development through formulation and fill-finish. It was founded in 2018 by Bryan Hassell and is based in Billerica, Massachusetts.

HPTLS delivers direct quantitative measurement rather than model-dependent chemometric prediction, needs no dilution or sample prep, and returns results in under a minute, so the same method transfers unchanged from development scale to manufacturing scale.
