Appendix IV: Fluorescence
Additional information from the fluorescence section of the Pittcon Review article.
Manufacturer: Horiba Scientific
Product name: Delta Series (DeltaPro and DeltaFlex)
Fluorescence TCSPC lifetime systems
New this year: A simple to use filter based system (DeltaPro). A modular high-end system, comprising monochromators, polarizers, sources (LEDs, laser diodes, supercontinuum lasers) and detectors (including NIR) (DeltaFlex).
The following characteristics apply to both instruments except when stated otherwise:
Can be used for: Lab, process analysis
Measurement Mode: Lifetime fluorescence
Special Features: Can be used as phosphorimeter (DeltaPro only)
Software available as separate product.
Suggested applications: Kinetics, anisotropy and TRES (time resolved emission spectra), FRET, measurement of physical constants (such as local viscosity), binding studies and photophysical characterization of molecular interactions.
Unique features: Fast: measurements from 25ps to seconds
Best of the Week: EAS Conference Coverage, IR Spectroscopy, Microplastics

FT-IR Analysis of pH and Xylitol Driven Conformational Changes of Ovalbumin–Amide VI Band Study
November 21st 2024This study uses Fourier transform infrared (FT-IR) spectroscopy to analyze how the globular protein ovalbumin's secondary structures transition under varying pH conditions in the presence of the cosolvent xylitol, highlighting the role of noncovalent interactions in these conformational changes.
