MAVERICK is powered by Raman spectroscopy and a purpose-built De Novo Model. The De Novo Model is explicitly built on media chemistries and device physics, not on empirical data. It automatically interprets the spectra and quantifies process parameters enabling simultaneous measurements of glucose, lactate, and total biomass. This is achieved without the costs, complexities, and risks associated with conventional Process Analytical Technology (PAT) methods. There is no need to grapple with complex empirical models, reagents, or unreliable auto-sampling systems to implement in-line bioprocess analysis.
