Trilogy Laboratory Fluorometer

Trilogy® is a powerful yet easy to use instrument that offers many benefits for benchtop analysis of samples. Its all solid-state design (no moving parts) utilizes light emitting diodes, sensitive photodiodes, solid glass filters, and electronics to ensure reliable and repeatable readings with no instrument drift. Sensitivity is maximized and pre-set providing a broad measurement range from minimum detection levels to maximum linear concentrations without instrument adjustments. Up to 18 different calibrations can be stored, each calibration performed with up to five concentration standards. Data can be output directly into an Excel spreadsheet during measurements via USB or serial connection. 

Trilogy can be used for fluorescence, absorbance, or turbidity measurements by simply snapping in the appropriate module. Standard modules are pre-configured for select applications; custom modules can be built for user-specific applications. The Trilogy’s small, compact design makes it a great addition to any laboratory analyzing fluorescence, absorbance, or turbidity properties of natural water samples. 

Snap-in modules are configured with the optical components necessary for the application of choice; changing applications is as easy as snapping in a different module.

Product Highlights:
  • Configurable for numerous applications

  • Quickly change applications by snapping in a different module

  • Store up to 18 user-defined multipoint calibrations

  • Measure both raw fluorescence and direct concentration for a sample

  • Easily export data to an Excel spreadsheet while measuring samples

Frequently Asked Questions

Frequently Asked Questions

How do I know what module to select on the Trilogy GUI?


Fortunately this is easy and straightforward to answer. Each Trilogy module has information on the label that needs to be input into the Trilogy GUI (Graphical User Interface) telling the Trilogy what module is being used. The Trilogy then accesses programming to define the LED power requirements and adjusts the LED current drive appropriately. Even the development kit and most custom modules will list the GUI Selection on the label. If not, you can contact support@turnerdesigns.com for assistance. For the Development Kit you should select the option that is determined by the specific LED you are using. Whether you are setting up the Trilogy for the first time or changing modules and applications, this information is required.




I was reading a sample and now my Trilogy has a blank screen and is non responsive. What can I do?


The sample may have oversaturated the detector. Power off the Trilogy, then wait for 5 seconds and reapply the power.




The Trilogy does not seem to be communicating with the computer. What can I do?


There are several things you can check to troubleshoot communication problems.

  • Make sure no other programs are using the serial port that the Trilogy is connected to.
  • Using a terminal program such as HyperTerminal open a new file and configure the settings for 9600, 8, none and 1. The flow control should be set to none. Save this file.


  • After you have completed this make a measurement and the data should be displayed in the terminal program window.
  • Also check that you are using the appropriate cable and that both ends are connected. If you are using a newer computer that only has a USB port make sure that your USB to serial adapter has the proper drivers installed and operating. You can refer to the Trilogy Cable Guide for recommendations of a serial adaptor.




What cuvette or sample vial do I need to use for my application?


Please refer to the Trilogy Optical Specification Guide for a listing of suggestions by application.




What method does the Trilogy use for Chlorophyll Acidification and Non-Acidification calculations?


When in direct concentration mode the following calculations will be used to calculate corrected chlorophyll and pheophytin a values for the acidification method and the corrected chlorophyll values for the non-acidification method.




What are the optical specifications for the application modules available for the Trilogy?


Please refer to the Trilogy Optical Specification Guide for information regarding filters, LED’s, linear range and MDL by application.




Can you provide me some information on how the Trilogy absorbance modules work?


Please refer to the following document for an overview of absorbance.
http://docs.turnerdesigns.com/t2/doc/appnotes/S-0141.pdf




What is the Minimum Detection Limit for the Trilogy phosphorus module?


0.033 µM or 0.033 micromoles/Liter, which is equivalent to 1 µg/L.




What is the Turner Designs Development Kit and how does it work?


The Turner Designs Development Kit P/N 7200-080 allows user the flexibility to design their own modules. Please refer to the manual for further information.




What turbidity standards should I use to calibrate the Trilogy?


GFS Chemicals has developed and certified new turbidity standards that are specifically engineered for optimal performance of Turner Designs instruments. The Trilogy has specific primary turbidity standards that should be used when calibrating.

10 NTU - GFS Part Number 8502
100 NTU - GFS Part Number 8503
1000 NTU - GFS Part Number 8699

I received the following error, “N700 voltage too low” on my Trilogy. What does it mean?


One of the possible causes for this error is dirty or noisy AC power. In some cases, this error can be eliminated by using a UPS (uninterruptible power supply) or other power line conditioner that can help to correct poor power line conditions.




Is there a standard that can be used for the in vivo Chlorophyll module on the Trilogy?


P/N 6500-120 can be used with the in vivo chlorophyll module. We have established a calibration correlation for it which is listed below:




Where can I find the spreadsheet for external calibrations using the Chlorophyll acidification module P/N 7200-040(-W)?


The spreadsheet can be downloaded at http://docs.turnerdesigns.com/calc/chlor-acidification-calculation-spreadsheet.xlsx Instructions for using the spreadsheet are located on row 36.




How do I know which cuvette or vial is the best option for my application?


We have put together a quick reference to help you decide, please visit http://docs.turnerdesigns.com/t2/doc/tech-notes/S-0256.pdf




How can I monitor Algal Growth in 25mm test tubes?


The C-FLUOR Submersible Probe may be a better option for you. Learn more in this Technical Note.
