Turner Designs Databank: What is it? How does it work? Why participate?
Welcome to 2007! Turner Designs is excited to start the New Year with seven new products. We are continuously expanding our line of applications and submersible platforms. The monitoring and research fields invariably require versatile sensors that include reduced size, lower power consumption, adaptable communication as well as a growing list of applications. The launch of our new Ultra Violet Cyclops sensors used to detect CDOM, Oil or Optical Brighteners, and the new C6 Multi-Sensor Platform is intended to provide additional flexibility.

Our list of new products include:

C6 Multi-Sensor Platform fluorometer
CDOM Cyclops
Crude Oil Cyclops
Optical Brightener Cyclops
Titanium Cyclops available in any version
RED PhytoFlash
Histamine Module

All of our instruments can be built for specified custom optics because we understand that research needs are not the same throughout varying environments and applications.

In this edition we'd like to highlight our new website. It includes updated technical and application information as well as new product brochures and spec sheets. We are also getting ready to introduce our new Grants program that will enable researchers to apply for a free Turner Designs instrument for upcoming projects.

Yours Truly,
Chelsea Donovan

Environmental Marketing Manager

C6 Multi-Sensor Platform

fluorometerThe C6 Multi-Sensor Platform is now available. The new optical platform, with factory installed temperature and depth sensors, can integrate up to six Cyclops sensors including our new line of UV and turbidity sensors. C6 Multi-Sensor Platform was designed to provide intelligent interface capabilities, flexible optical sensor integration and increased power for extended deployments.

With increasing optical applications and the need for more flexibility we feel the C6 Multi-Sensor Platform is an excellent choice. New features include a bio-fouling wiper, robust battery and easy to navigate user interface. Inquire now for a quote!

Available Sensors:

In vivo Chlorophyll a
Blue Green Algae (phycoerythrin)
Blue Green Algae (phycocyanin)
Rhodamine Dye
Fluorescein Dye
Optical Brighteners
Custom Optics also available!


Ultra Violet Cyclops Sensors

Our new line of UV sensors includes a CDOM, Crude Oil, and Optical Brighteners model.

Researchers can utilize a CDOM Cyclops to monitor colored dissolved organic matter in coastal waters as well as detect ship ballast water exchange before entering ports.
Crude Oil
Crude Oil Cyclops can be used to monitor oil dispersal during spill response efforts, mapping programs or on monitoring platforms.
Optical Brighteners
The Optical Brighteners Cyclops can be used to detect human waste signatures, such as fecal sterols and detergent surfactants derived from on-site wastewater systems and community wastewater treatment system leakage.

All Cyclops models can now be ordered with a titanium housing and connector to withstand high temperatures and hypersaline environments. Depth rating is 600 meters.

RED PhytoFlash Submersible Active Fluorometer

Variable Fluorescence for Cyanobacteria and Prochlorophytes

Researchers interested in quantifying variable fluorescence specifically for cyanobacteria and prochlorophyte communities can now order a RED PhytoFlash.

PhytoFlash is now Available with Analog Output for Easy CTD Integration!

The PhytoFlash is now able to output analog data specifically for CTD integration. Two streams of analog data are available. The yield (Fv/Fm) parameter is automatically provided and users can choose either Fo or Fm as the second parameter.


Histamine Module for Trilogy

fluorometerLaboratory Detection of Histamine in Fish Tissue

The Histamine Module for the Trilogy Laboratory Fluorometer is now available. Users detecting Histamine in seafood, in accordance with the AOAC Official Method 977.13, can now purchase a Histamine Module. A Histamine optical kit is also available for the 10-AU Field Fluorometer.

The equation for determining in-vivo Chlorophyll a is:
chl a (mg Chl a/m-3)= KF. K is the in-vivo fluorescence sensitivity coefficient (mg Chl a/m-3/ fluorescent unit). F represents the in vivo fluorescent response.

What are some factors that can affect the K value?

1) Species Composition. The K value is species dependent. The ratio of chlorophyll a to plant carbon can be anywhere form 25 to 100%. Differences in cell packaging, chloroplast shape and cell morphology can also result in varying K values.

2) Physical Environmental Parameters. The in vivo fluorescence efficiency of chlorophyll a is dependent on light exposure and temperature. At low light levels, algal cells can optimize the light uptake by pushing chloroplasts to the outer edge of the cell, or by producing more chlorophyll per cell. Both of these responses can result in fluorescence data that falsely represents the algal biomass. Temperature is also a consideration. Fluorescence is indirectly correlated to temperature. As the temperature increases the fluorescence will decrease. This can be corrected through temperature compensation. The temperature coefficient for in vivo chlorophyll a is 1.4%/ °C or .78%/ °F.

3) Physiological state of the cell. The presence of senescent cells (or dying cells) will also affect the K value. There are three outcomes of light energy that is absorbed by chlorophyll a contained in algal cells; 1) it is channeled towards photosynthesis, 2) it is given off as heat, or 3) it is re-emitted as fluorescence. This is why healthier cells fluoresce less than senescent cells.

See our E-support page for a complete description of in vivo chlorophyll a theory, measurement and calibration considerations.


Alliance for Coastal Technologies

We are excited to announce that the Alliance for Coastal Technologies recently voted Chelsea Donovan, our Environmental Marketing Manager, onto their council of stakeholders. ACT is a
NOAA-funded partnership of research institutions, resource managers, and instrument manufacturers from around the world dedicated to fostering the development of effective and reliable emerging technologies. Chelsea's term will span 2007-2010 and involve participation in meetings focused on emerging technologies as well as upcoming evaluations and workshops.

Turner Designs Databank

In response for more 'real-world' data from our customers, Turner Designs has launched the TD Databank Program where we present examples of customer research for all instruments and applications. The Databank is organized according to instrument type and application and offers our users real-world examples of how researchers and technicians are using Turner Designs instruments in their work. In addition to providing meaningful information for our customers, by having a description of your work highlighted on our website, it will serve as a means of reaching a greater number of scientists around the globe. We see this as a highly effective means of assisting our users in making informed decisions. In order for this type of program to succeed, we need information from you on your application and how a Turner Designs fluorometer is helping you.

fluorometerWe have designed the TD Databank to make submitting an application summary as easy as possible. The entire process should not take more than 20 minutes. We ask for a brief description of your research, and how you use Turner instruments. Also, a picture or graph of data collected with Turner instruments is requested. To show our appreciation for your databank articles, we will send you a Turner Designs sports bag. Claim your sports bag now by submitting your Databank article!

We hope you will join us in this exciting and useful program by sharing your knowledge and experience with scientists and technicians around the globe. To take part, please visit
