Filter Effects

Synchronous fluorescence spectroscopy is frequently used to resolve multiple components in mixtures without separation. However, uncompensated inner-filter effects can lead to unexpected and/or large quantitative errors. An instrument and a method that correct for primary and secondary inner-filter effects in synchronous fluorescence spectroscopy have been designed and characterized. A bifurcated fiber-optic-based diode array fluorometer that simultaneously measures front-surface fluorescence and absorbance was constructed. A transfer function that mathematically describes the coupling efficiency between the excitation and emission legs of the fiber optics is defined and characterized. Once characterized, such a fluorometer is capable of calculating what the fluorescence measurement would be in the absence of inner-filter effects. Several experimental procedures for determining the instrument's transfer function are compared and discussed. Applications of the various procedures to experimental fluorescence inner-filter corrections to problematic samples are demonstrated.

A fiber optic device sensitive to humidity is detailed and modelled by ray tracing based on Monte Carlo simulation. The device is intended primarily for monitoring humidity in the microenvironment of wounds without removing the wound dressing and thus disturbing the wound-healing process. To produce the sensor, cladding is removed from a segment of its polymer-fiber and mesoporous SiO2 nanoparticles are deposited in the exposed zone. This introduces an additional light-transmission loss. The extent of such loss is related to the relative humidity of the environment. Such a relationship, embodying the essence of the sensor’s modulation principle, is examined in this paper by ray tracing based on Monte Carlo simulation. The sensor is explained in detail and its performance is characterised.
