Portable fluorescence analysis for crude and heavier oils, with saved calibrations, recorded results and PMA support.
The Turner Designs TD-550 is a portable UV fluorescence analyser for discrete oil-in-water samples. Its single optical channel is suited to crude oil and other heavier oils, including diesel, lubrication oils and fuel oils.
A full-colour touchscreen supports channel and cuvette selection, calibration and extraction-ratio settings. Saved calibrations and site locations help organise repeat testing without re-entering the same information for every sample.
The instrument records a timestamp, location and result for each analysed sample. Review the history and graphs, then export data using USB or Micro SD for further analysis.
Use direct or raw calibration and retain multiple calibrations for different targets or sites. The chosen oil and preparation procedure determine how to interpret the result.
The manufacturer supports popular extraction solvents and TDHI’s No-Solvent Method. Select and validate the procedure for the sample matrix rather than assuming every sample can be measured untreated.
Sort stored results by date, location or calibration and graph filtered reading history. Logging makes it easier to compare site checks and investigate changes over time.
Published manufacturer specifications are a starting point. Confirm the supplied configuration, target sample and installation conditions with PMA.
UV fluorescence; a single optical channel suited to crude and heavier oils.
Crude oil, diesel, lubrication oils and fuel oils. Confirm response and calibration for your specific product or mixture.
5 ppb–5000 ppm, dependent on target oil. This is a published range, not a universal detection limit for every sample matrix.
External 90–240 VAC power supply; published battery operation of 6–8 hours. Actual field planning should include charging and the intended use.
USB and Micro SD output. Display units include ppm, ppb, mg/L, µg/L and raw signal.
Direct and raw calibration; multiple calibrations and site locations; timestamped sample results and graphing. Manufacturer brochure lists CE approval.
Use a defined sampling and preparation method, with a calibration relevant to the oil being assessed.
Check discrete samples when assessing treatment performance or investigating a changing oil response. Match the reporting basis to the method required for your process.
Investigate suspected contamination in cooling circuits or condensate samples. Representative collection and controlled preparation are essential at low concentrations.
Use a defined target-oil calibration for crude, diesel, fuel or lubrication-oil samples. Discuss mixed or changing oil compositions with PMA.
The manufacturer lists stormwater and oil-in-soil analysis. Soil work requires suitable extraction and reporting calculations; the analyser is not a direct in-ground soil sensor.
Start with the decision you need to make and the reference method, if one is specified. Establish representative sample collection, preparation, blanks and calibration checks for your target and water matrix.
The manufacturer states that results can be correlated to official laboratory methods such as USEPA 1664A and ISO 9377-1. Demonstrating that correlation requires a validated procedure and representative comparison samples; it is not an automatic equivalence for every oil or application.
If the target includes lighter fuels, BTEX or gas condensates, review the TD-560’s second optical channel. TD-550 suitability should be assessed against the actual oil and sample conditions.
Review the measurement principle, published specifications and available features for this product.
Send your sample conditions and operational objective so PMA can review the right configuration.
Read PMA’s existing solvent-free extraction article. Read the TD-550 and TD-560 comparison.
It measures a fluorescence response from a prepared sample using the selected optical channel. Calibration relates that response to a defined target oil or reporting basis.
No-solvent analysis is a supported option, but its suitability depends on the oil, matrix and required result. Agree the procedure and validate it before routine testing.
TD-550 uses one optical channel for crude and heavier oils. TD-560 includes that channel and adds another for lighter hydrocarbons.
Portable analysis with a second optical channel for lighter hydrocarbons as well as the oils measured by the TD-550.
Continuous UV fluorescence measurement for oil contamination, process protection and treatment monitoring.
Continuous chlorophyll-A fluorescence measurement for algae-bloom warning and water-intake protection.
