Achieving Superior Raman Measurements: Understanding and Avoiding Detector Saturation

One of the primary technological advantages of Tornado Raman analyzers over conventional Raman devices is the significantly higher optical efficiency delivered by our HTVS™ platform (described in this prior blog post). With 10x to 30x more photons per second, Tornado systems provide superior spectral data for better precision and sensitivity for PAT measurements, as we […]

Optimized Perfusion by Capacitance Process Measurement & Control

Recent studies on biotherapeutic protein production have shown perfusion processes as a superior technology vs. the traditional batch and fed batch approaches. Due to its associated process stability and reducing effect of varying conditions inside the bioreactor, Perfusion can deliver lower production costs and higher titer, especially in the case of low titer or fragile […]

OD600 Measurement Results Using Spectrophotometers & Online OD Instruments

Spectrophotometers can be an excellent tools to monitor the growth phase or determine cell concentrations in microbial fermentation processes. Despite of the fact that these instruments are generally utilized to measure absorbance of particular samples (concentration measurements), spectrophotometers are also used to quantify light scattering running at 600 nm wavelength. This method, commonly known as […]

Coulometric Titration vs Volumetric Titration: Using KF titrators to determine water content

The Karl Fisher titration method was published to determine trace amount of water samples in non-aqueous systems that contained sulfur dioxide. It is currently the standard method used to calculate the moisture content in various products. When looking at titration analysis methods, it can be a challenge to determine which to use. This article takes […]
