As we get ready to roll out three new additions to our smart-sensor portfolio, we sat down with Product Manager Steve Sewell to talk about our new FDOM, Crude Oil and Fluorescein WT fluorometers. In-Situ: Steve, why was it important to add these sensors to the Aqua TROLL portfolio? ...
Product Description The Cyclops-7 Logger is a completely self-contained waterproof device designed to connect to one Turner Designs Cyclops-7 sensor at a time. PME currently offers two variations of this sensor, fixed and interchangeable. The logger records measurements internally with a variety of rates to choose from. The data is then offloaded from the logger via a USB cable. The logger can ...
We supply cuvettes for spectrophotometer, fluorometer and other instruments. The first cuvette sale order from south africa is for tube cells and sample cells. ...
Date:2011 Location: New South Wales Australia Purpose: To determine if the SMF4 could be used to monitor the output from a grey water recycling plant and conclusively differentiate the output water between potable and recycled. Background STS has had a long history of closely working with academia in the development of portable fluorescence equipment. In particular STS have worked Prof ...
The reduction of enzyme activity with increasing toxicant exposure has been quantified in single rotifers with image analysis or in populations with a fluorometer. Results from changes in rotifer stress protein gene expression as a result of toxicant exposure are summarized. ...
In this study, the aim was to use in situ fluorescence sensors to track the performance of a DEWATS, consisting of an anaerobic baffled reactor (ABR) coupled to anaerobic filter (AF) and constructed wetland (CW) treatment processes. A submersible in situ fluorometer equipped with tryptophan (TRP) and chromophoric dissolved organic matter (CDOM) sensors was deployed in each ...
During the field campaign, the dye tracer was monitored with field fluorometers and the turbidity was observed with an optical backscattering sensor interfaced to an OEM data acquisition system. ...
However, optical instruments called fluorometers can "see" dissolved petroleum hydrocarbons in water, and at very low concentrations. ...
The Solution Optical instruments called fluorometers can very easily detect and measure dissolved petroleum hydrocarbons in water, and at very low concentrations. ...
Two field fluorometers, devoted either to natural organic matter (NOM) or to tryptophan-like fluorescing substances, were tested for the characterization of a large set of water samples (n = 263) impacted to various degrees by untreated or poorly treated urban sewage. Both fluorometers yielded consistent results when testing discrete samples. A nonlinear ...
Recycled water plant monitoring Date: 2011 Location: New South Wales Australia Purpose: To determine if the SMF4 could be used to monitor the output from a grey water recycling plant and conclusively differentiate the output water between potable and recycled. Background STS has had a long history of closely working with academia in the development of portable fluorescence equipment. In ...
Solution The STS SMF4 portable fluorometer offers two separate solutions to this problem. Firstly it can offer a instant result from a discrete sample taken from the water body. ...
Sewer Misconnection Survey Date: March 2010 Location: Edgebaston Birmingham UK Purpose: To test the application of the SMF4 portable fluorimeter in the detection and quantification of organic pollution from faecal matter in Surface water Sewers. Background STS was invited independently by the Environment Agency and Severn Trent water to carry out a series of monitoring operations in an ...
Good Water Company (Testing Service) Groundwater samples were submitted by well owners from different regions of New Mexico (around Espanola region) in a water clinic sponsored by the Good Water Company. Problem/Task The groundwater in this region is contaminated with natural uranium, often above the EPA maximum contaminant level of 30 ppb uranium. ANDalyze Solution These samples were tested ...
One of the most important discoveries in the last decade is that DNA/RNA are not only materials for genetic information storage and transfer, but also catalysts for a variety of biological reactions, and thus called catalytic DNA/RNA, (deoxy)ribozymes, or DNA/RNAzymes. Because metal ions play essential roles in the structure and function of DNAzymes, the study and application of these new ...
On-line monitoring of PHA concentrations in activated sludge was achieved by using a fluorometer equipped with a flow cell and the time point at which PHA concentration in activated sludge reached the maximum level could be identified. ...
Here we suggest the use of chlorophyll fluorometers in the undergraduate plant physiology classroom as one means to enhance conceptual learning of photosynthesis and its acclimation to changing environments. We also provide an overview of current research in photosynthetic acclimation to changing conditions, review the methodological considerations of making good Fv/Fm ...
