Applied Photophysics - For Circular Dichroism and Stopped-flow Spectroscopy

Techniques Overview

Applied Photophysics is a world leading manufacturer and supplier of circular dichroism, stopped-flow, and laser flash photolysis instrumentation. Through a constant process of Research and Development Applied Photophysics has maintained its leadership in these three key technology platforms. Applied Photophysics is also the only supplier of global analysis software dedicated to these research areas.

Circular Dichroism

Circular dichroism (CD) is a spectroscopic technique used in the study of chiral molecules. Circular dichroism is the differential absorbance of left- and right- circularly polarised light, and is particularly suited to studying the secondary and tertiary structure of biological molecules.

Stopped-Flow

Stopped-flow is a technique for studying the reaction mechanisms of fast chemical reactions.  Two or more solutions are forced to mix and flow through a measurement cell. The flow is then suddenly stopped, and the reaction studied using a spectroscopic technique such as absorbance, fluorescence or circular dichroism.

Laser Flash Photolysis

Laser flash photolysis is a technique capable of studying extremely fast reaction kinetics at the nanosecond time-scale.

Applied Photophysics has been supplying laser flash photolysis instruments since 1973. The experience gained during this period has resulted in the LKS.60 spectrometer which offers both ease of use and flexibility, including special configurations such as combined stopped-flow and/or flow-flash systems.

Global Analysis

Global Analysis is an analysis technique where multiple data sets are analysed simultaneously in order to get more robust fitting and therefore more accurate results.
