Environmental Sample Processor

  • Product Type:
    • Samplers
  • Product Category:
    • ESP

The Environmental Sample Processor (ESP) provides in situ collection and analysis of water samples from the subsurface ocean. The instrument is an electromechanical, fluidics system designed to collect discrete water samples, concentrate microorganisms or particles, and automate application of molecular probes in order to identify microorganisms and their gene products. Data generated are then available for remote retrieval and analysis in near real-time.

The system is a modular design consisting of a core sample processor (the ESP), analytical modules and sampling modules. The core ESP provides the primary interface between the environment and a set of DNA and antibody-based sample processing technologies that are applied onboard the instrument in real-time. In addition, the ESP can be used to archive samples for a variety of analyses after the instrument is returned to a laboratory. The system provides expandability to allow installation and control of secondary analytical modules for parallel processing of collected samples.
