UviLux Tryptophan Overview
Building upon years of research into the measurement of water quality using UV fluorometers, the UviLux Tryptophan is a highly sensitive, robust sensor designed for detecting and monitoring tryptophan in natural and process waters, giving an indication of bacterial contamination and overall water quality. Sensitive beyond ppb level, the UviLux Tryptophan fluorometer is an ideal tool for detecting sewage contamination.
UviLux Tryptophan Features
- In-situ, real time monitoring of Tryptophan
- Highly sensitive readings to 0.03 ppb
- Couple with FDOM sensor to remove environmental interference
- Easy to integrate with monitoring platforms and systems, or combine with Hawk for on the spot readings and logging
- Depth rated to 1000m
- Excellent turbidity rejection and high ambient light rejection
- Service and support from dedicated technical team
Applications
- Real time monitoring of sewage contamination in rivers and lakes
- Bacterial contamination monitoring in groundwater
- Assessment of overall water quality in catchments and natural waters
- In situ bacterial contamination monitoring for shellfish aquaculture
- Detection of bacterial contamination in process waters

The sensitivity and calibrated range of each UviLux Tryptophan sensor has been standardised by cross-correlating each calibration solution against a certified reference standard of quinine sulphate using a bench-top spectrofluorometer. Fluorescence is reported in Quinine Sulphate Units (QSU), where 1 QSU is equivalent to the fluorescence intensity recorded from 1 ppb quinine sulphate at an excitation wavelength of 347.5 nm and an emission wavelength of 450 nm. Factors are provided for selected compounds to convert the fluorescence output from QSU to ppb of the compound of interest
