STS have produced the fully portable SMF4 Fluorimeter which allows instant quantification of Tryptophan(an indicator of BOD) in water samples on site, allowing immediate decisions to be taken regarding water quality and control actions.
This technique simplifies and quantifies investigations into cross connected sewers, illegal discharges to surface waters and monitoring consent agreements. Operation and control of the instrument has been streamlined so that it can be used by non scientific staff.
• Portable instrument for the measurement of organic pollutants in water (BOD equivalent)
• Instant reading on site without laboratory analysis costs and timescale
• Tracing pollutant sources back to origin
• Data logging & remote monitoring capabilities
• Can be used by unskilled operators for routine monitoring
• Laboratory use for pre-screening BOD samples to reduce multiple dilutions
• Monitoring of river water quality’s impact on bathing waters
• Tracing organic pollution in storm water sewers
• Monitoring discharges to water courses
Application of the SMF4 to water analysis.
The design of the SMF4 draws heavily on the research carried out by Prof Andy Baker at Birmingham University, who showed that tryptophan is an excellent indicator of anthropogenic pollution and that its measurement by fluorescence was straightforward. Further research allowed strong correlations to be made between tryptophan and the standard Biological Oxygen Demand test (BOD), but with an instant result rather than a 5 day delay.
The instrument can be used on site for instant sampling and also in a data logging mode utilising flow cell technology, to capture a set of user defined readings over a desired timescale. The instruments internal memory is capable of holding up to 2000 sample records before requiring download. Data can be downloaded through the RS232 port for further analysis.
Adjustable sensitivity settings mean that the instrument may be used in a range of different pollutant levels without the need for timely and costly dilutions.
