Environmental Sample Processor (2G)

Persistent presence

During the development of the ESP, several iterations were necessary until we had a stable, working instrument.  We call this instrument the Second-Generation ESP or 2G ESP.

2G ESP system architecture

There are three major components of the 2G ESP:

The ESP core

  • Provides power, reagents, and data/control communications
  • Collects small to moderate sized samples (from milliliters to two liters)
  • Performs automated sample processing, sample archival, and real-time probe array analyses (sandwich hybridization arrays and enzyme-linked immunosorbent assays).

Analytical modules

  • Custom analytical devices fitted to the core ESP
  • Take the sample collected and processed by the core and can perform analyses where small sample volumes dominate (microliters to milliliters)
  • Currently performing quantitative-PCR


External sampling modules

  • Meet specialized sampling requirements posed by deep-water environments.
  • Provide for large sample volume concentration (up to two liters).
