Tornado Spectral Systems has recently introduced the Process Guardian™ Raman spectrometer (PGR) which is a process-ready version of their HyperFlux™ PRO Plus (HFPP) system. Customers who are considering adding this new system are interested in knowing whether their existing models can be transferred to the Process Guardian™ Raman. Fortunately, the two systems are based on the same high-throughput and high-resolution High Throughput Virtual Slit (HTVS™) technology, making model transfer straightforward. To demonstrate the transferability of models between the two systems, we conducted an experiment using 30 samples containing glucose, lactate and glutamine in DEME growth media to simulate bioprocess conditions and measured these samples using both systems.
