The present invention provides methods and apparatuses for in situ chemical analysis of liquid sample for the collection, identification, and measurement of chemical moieties, such as, biotoxins, organic compounds, or chemical contaminants, in aquatic environments. The apparatuses of the present invention relate to an automated in situ sampler for chemical stressors that adversely impact biological systems in aquatic environments. The apparatuses of the present invention are designed as a means to automatically collect liquid (e.g., water) samples and analyze them for the presence of chemical moieties. The apparatuses of the present invention are designed to automatically collect multiple liquid samples, extract and separate chemical moieties contained within the samples, and analyze the chemical moieties to determine the composition and concentration of the chemical moieties over time and space. The apparatuses of the present invention can be used for in situ sample collection and analysis in all weather conditions safely and economically without the need for vessels or human involvement.

Automated in situ contaminant detection system

An apparatus and method for analyzing liquid samples employs first and second bidirectional ports that permit liquids to be introduced to first and second liquid waveguide capillary cells at the same time. The direction of liquid flow through the apparatus and roles of components may be reversed to prevent or overcome obstruction by particulates and other debris. The apparatus and method can detect and map colored dissolved organic matter and can detect, discriminate and map algal species or algal blooms including red tide in an automated, unattended manner within large aquatic systems.
