1. Linearity may be checked by diluting a sample 1 1 or some other convenient ratio If the sample is still in the linear range the reading will decrease in direct proportion to the dilution If the reading does not decrease in direct proportion to the dilution or if the reading increases the sample is beyond the linear range of the fluorophore Opti Trace User s Manual Page 12 6 Temperature Considerations Fluorescence is temperature sensitive and depends on the dye used As the temperature of the sample increases the fluorescence decreases For greatest accuracy determine the temperature coefficient of the dye being used record the sample temperature and correct the sensor output for changes in temperature See following table 2 for examples of dye temperature compensation coefficients Information on how to apply these corrections is included in the Turner Designs Application Note A Practical Guide to Flow Measurements see the following URL http www turnerdesigns com t2 doc appnotes 998_5000 html Dye Correction C Correction F Table 2 Examples of Te t ti Rhodamine WT 0 026 0 0144 ne EM TM Fluorescein 0 0036 0 0020 fluorescent dyes Warranty Terms Turner Designs warrants the Opti Trace and accessories to be free from defects in materials and workmanship under normal use and service for a period of 12 months from the date of shipment fr2. 2 2 2 220400000020000000000000000000000 17 FINAL REQUIREMENTS CUSTOMER 18 APPENDIX D rE 19 FIGURE 7 INLET PLUMBING KIT 2 nennen esses esee 19 FIGURE 8 DRAIN PLUMBING KIT 5 2 nennen etes enin 20 FIGURE 9 OPT TRACE FLUOROMETER SHOWING IDENTIFICATION OF KEY PARTS 21 Introduction Description The Turner Designs Opti Trace fluorometer is an accurate single channel fluorometer designed to measure and provide an output signal proportional to the concentration of a fluorescent dye In a representative application the Opti Trace will be used with a data collection system to monitor and control the level of treatment chemicals in industrial applications By combining the Opti Trace with a data collection system the exact level of a tracer dye can be measured which in turn can be used to control the addition of treatment chemicals assuming the tracer dye is tagged to the chemical of interest The fluorescent tracer dye is measured by passing the water containing the dye chemical containing water through a sample cell glass tube in the Opti Trace fluorometer An excitation light source illuminates the solution and excites the dye in the solution which fluoresces at a different wavelength The intensity of the emitted lig
