Portable and light-weight, Amiscience's handheld fluorometer provides exceptional sensitivity, rapid-reading, and reliability at a much lower cost compared to the industrial standards. Determine whether goals, such as compliance with pollution regulations or implementation of effective pollution control actions, are being met. However, small scale HABs that introduce toxins into the water can be very harmful to animals and the general public and they can be difficult to detect if the proper instrumentation isn’t being used for monitoring. These parameters are used to identify the presence and the amount of specific molecules in a medium. Found inside – Page 219J. R. Alcala and E.

Lakowicz, ... Aquatic ecosystems are some of the most productive in the world, but they are also among the most fragile. Wenshe Liu . When oil spill response teams are dispatched to the scene of an oil spill it is critical they have the proper instrumentation to monitor the areas of contamination and the effectiveness of dispersants and burning techniques. Pricing & Availability. The C-ray enables the C3 to be deployed alongside a moving vessel at a slow speed while transmitting data over a cable. Dissolved Organic Material (DOM) exists in many forms ranging from naturally occurring humic acids to … Cyanobacteria have been found to be a numerically abundant faction of the phytoplankton community. Many water treatment plants monitor their source water prior to arrival for treatment and purification. Optical brighteners and tryptophan can both be measured and are proxy indicators of wastewater contamination.

Our laboratory fluorometer is configurable for parameters ranging from absorbance, fluorescence or turbidity. Some examples are: Characterize waters and identify changes or trends in water quality over time. Accordingly, regulations are established specifying low levels of living/viable organisms and how to detect them before releasing ballast water. The inadvertent introduction of invasive aquatic species to coastal waters when discharging ballast water cause both ecological and economic damage. Harmful Algal Blooms (HABs) can cause harmful conditions for humans as well as marine or terrestrial wildlife. Considering quick feedback regarding re-suspension is crucial, real-time measurements from on-site in situ fluorometers allow operators to manage dredge activities and react quickly if sediment levels exceed environmental limits. Real-Time data from the C3 can also be captured and viewed using Turner Designs’ C-Soft program.
