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
Getting accurate IR spectra on monolayer of molecules
April 18th 2024Creating uniform and repeatable monolayers is incredibly important for both scientific pursuits as well as the manufacturing of products in semiconductor, biotechnology, and. other industries. However, measuring monolayers and functionalized surfaces directly is. difficult, and many rely on a variety of characterization techniques that when used together can provide some degree of confidence. By combining non-contact atomic force microscopy (AFM) and IR spectroscopy, IR PiFM provides sensitive and accurate analysis of sub-monolayer of molecules without the concern of tip-sample cross contamination. Dr. Sung Park, Molecular Vista, joined Spectroscopy to provide insights on how IR PiFM can acquire IR signature of monolayer films due to its unique implementation.
