The primary goal of our Environmental Facility is to offer expertise and equipment to support different working groups in their routinely monitoring programs of Red Sea marine ecosystems.
Total Organic Carbon Analyzer (TOC) Aurora
The Aurora 1030W TOC Analyzer processes aqueous samples for analysis of total organic carbon (TOC), total inorganic carbon (TIC), and non-purgeable organic carbon (NPOC) content. Using heated persulfate oxidation technology, samples containing 2 ppb to 30,000 ppm of organic carbon can be analyzed. Up to 300 samples per 24-hour period can be analyzed. The Picarro δ13C-CO2 analyzer is coupled with an Aurora 1030W TOC Analyzer from OI, the system provides δ13C measurements of the dissolved carbon in water samples.
The TOC unit is mainly used to measure the levels of dissolved organic carbon and total nitrogen in seawater samples. The organic carbon of the sample is ultimately detected as carbon dioxide in a non-dispersive infrared (NDIR) detector after high temperature catalytic oxidation (HTCO).
Total Organic Carbon Analyzer (TOC) with Total Nitrogen (TN) Unit
The Total Organic Carbon TOC analyzers TOC−L CSH Shimadzu, ASI and Total Nitrogen adopts the 680°C combustion catalytic oxidation method, while providing an ultra wide range of 4 μg/L to 30,000 mg/L. These analyzers have a detection limit of 4 μg/L through coordination with NDIR. This is the highest level of detection sensitivity available with the combustion catalytic oxidation method.
Picarro CRDS is a rugged, compact, and field-deployable system that measures concentration and isotope ratios. The four primary analytical measurements of the instrument are the concentration of 12CO2, 12CH4, 13C-CO2, and 13C-CH4 with a resolution in parts per billion. Picarro Analyzers use time-based, optical absorption spectroscopy of target gases to determine concentration.
FlowCam is used for morphological analysis of particles (size, shape, etc…), namely the cells composing zooplankton. In addition, fluorescence can be used to further discriminate cell types similar to a flow cytometer.
Applications: monitoring harmful algal blooms (HAB); characterization of phytoplankton and zooplankton assemblages.
The Coriolis® µ, is a microbial air sampler specifically designed for the quantification and detection of biological particles such as bacteria, spores and pollen. Particles are collected and concentrated in a liquid sample allowing analysis of air samples using the methodologies available for the characterization of microbes from aquatic environments including PCR and flow cytometry.
