South Fork Instruments has announced the availability of the Kemtrak UV Spectra Process Analyzer, a multi-wavelength deep-UV photometer designed for real-time absorbance measurement of proteins, peptides, polypeptides, mRNA/DNA, amino acids, APIs, and process intermediates. The analyzer provides high-resolution continuous absorbance measurement from 190 to 440 nm, supporting applications in chromatography, filtration, biochemical production, and process monitoring.
This development is significant because bioprocessing teams are increasingly working with higher concentrations and more demanding purification steps, creating a need for more sophisticated monitoring equipment. The Kemtrak UV Spectra addresses this need by providing deep-UV performance, zero-dead-volume measurement, and verification tools needed to generate reliable inline data. Its stability and real-time multi-wavelength capability make it particularly suitable for chromatography, filtration, and high-value process streams.
The analyzer offers high-stability optical measurement with up to 10 user-selectable wavelengths, ±0.005 AU photometric resolution, and a 10 Hz sampling frequency for continuous real-time monitoring. To support accurate inline measurement, the system integrates zero-dead-volume hygienic measurement cells available in stainless steel, titanium, Hastelloy, Monel, PTFE, and PPSU, with window options in sapphire and UV-fused silica. Wetted surfaces are available with electropolished finishes down to Ra ≤ 0.38 μm.
Key features include multi-wavelength deep-UV absorbance measurement from 190–440 nm with up to 10 user-selectable wavelengths, high-resolution continuous measurement with ±0.005 AU photometric resolution and fast 10 Hz sampling, zero-dead-volume hygienic measurement cells in multiple wetted materials for fast response inline monitoring, mercury-free UV-xenon light source with up to two years of continuous operation, and integrated traceable verification with NIST-compliant reference standards and verification port.
The implications of this technology are substantial for industries requiring precise biochemical monitoring. The ability to measure substances like mRNA/DNA and proteins in real time with high resolution could accelerate research and production timelines in pharmaceutical development, biotechnology, and industrial biochemistry. The analyzer's compatibility with various materials and its hygienic design make it suitable for sensitive production environments where contamination must be minimized.
The Kemtrak UV Spectra adds a deep-UV measurement option to South Fork's instrumentation lineup for chromatography, filtration, and real-time process monitoring.
