South Fork Instruments Launches Kemtrak UV Spectra for Enhanced Bioprocessing Monitoring

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.

John Daly, Technical Director at South Fork Instruments, noted that bioprocessing teams are working with higher concentrations and more demanding purification steps than ever before. The Kemtrak UV Spectra provides the 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 a strong fit for chromatography, filtration, and high-value process streams.

The Kemtrak UV Spectra 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, a 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 Kemtrak UV Spectra adds a deep-UV measurement option to South Fork's instrumentation lineup for chromatography, filtration, and real-time process monitoring. This development is significant for industries requiring precise biochemical monitoring, as it enhances data reliability and operational efficiency in critical processes. The analyzer's advanced capabilities could lead to improved product quality, reduced waste, and more efficient resource utilization in bioprocessing and related fields.
