Continuous Low-Level Aquatic Monitoring (CLAM) - C.I.Agent®

Supplier: CI Agent Solutions

The C.L.A.M. extracts the water in-situ with the same technology the labs use on the bench.

PRODUCT DESCRIPTION:
The C.L.A.M. is a state-of-the-art small submersible extraction sampler using EPA approved SPE (Solid Phase Extraction) media to sequester Pesticides, Herbicides, PAH’s, TPH, and other trace organics from water. The C.L.A.M. uses low flow rate extraction sampling (5-60 ml/minute), where water is drawn continuously through the extraction media. It provides an extraction event that can be hours, days or weeks long, allowing capture of trace pollutants from illicit and episodic events. It provides a pre-extracted quantitative sampling event representing up to a hundred liters of water, lowering the laboratories’ detection limits a hundred fold. The small, dry extraction disk is all that is sent to the laboratory for solvent elution and analysis.

 

PRODUCT APPLICATIONS:
The C.L.A.M. can be used in applications such as sampling of urban water systems, rivers, monitoring wells, drinking water systems, watersheds and lakes, agricultural runoff, storm water and marine environments. There are approximately 100 substances controlled by regulations and that list grows every year with lower detection requirements. The C.L.A.M. is your water monitoring solution.

 

PERFORMANCE SPECIFICATIONS:

  • Low detection; up to 100 liters with a single field extraction
  • Uses low flow rate extraction sampling (5-60 ml/minute)
  • The small extraction disk is the only item to be sent to the lab for solvent elution and analysis
  • Weighs just over one pound, including the four (4) AA batteries
  • The C.L.A.M.’s resilient nylon body housing has Luer lock fittings which allow the filter to be locked to the C.L.A.M.’s body, and interlocking of different filter types in two stage assemblies. Each disk comes pre-conditioned with or without 10 ug of Terphenyl d-14 field surrogate added
  • The C.L.A.M. SPE disk media can be specific for non-polar analytes, polar compounds and chelating resin disks to sequester multivalent metal cations all at a neutral pH
  • Micro pump suction draws the water through the extraction media first, preventing analyte surface absorption on tubing and pumps
  • The media and housing uses special lofted filters to retard fouling
  • Unique flow design prevents contamination in tubing or pump

 

BENEFITS:

  • Comes in a waterproof Pelican® field case
  • The C.L.A.M. measures 2.5” by 8”
  • The C.L.A.M. runs submerged on four AA batteries
  • Just sending the small, dry extraction disk to the laboratory for solvent elution and analysis saves costs of extraction, expensive cooler shipments of sample bottles, and seven day holding time requirements.

 

C.L.A.M. Complete Kit
The C.L.A.M. comes in a sturdy, waterproof, part molded Pelican® field case. The kit includes:

  • The C.L.A.M body constructed with a resilient nylon body housing
  • A micro pump with integrated microcircuits and switch, fused into the body with waterproof polymer potting
  • Calibration syringe and tubing
  • One SPE disk screw on protection cap
  • One threaded screw in battery housing plug
  • Two rubber gaskets for the battery housing plug
  • One 4 AA battery holder
  • Two conditioned Oasis HLB SPE media disks.
  • A waterproof, part molded Pelican field case

 

Solid Phase SPE Extraction Disk
The field hardened housing contains C-18 media which is acceptable for the extraction of TPH, PAH’s Pesticides and all non-polar groups. Like all the C.L.A.M. disks, it has Luer lock fittings which allow the filter to be locked to the C.L.A.M. body and interlocking of different filter types in two stage assemblies. Each disk comes pre-conditioned with or without 10 ug of Terphenyl d-14 field surrogate added.

 

Solid Phase HLB Extraction Disk
This disk will retain a wide variety of non-polar and polar compounds such as: EPA 525 SOC’s, Pesticides, Pyrethroids, Herbicides, TPH, PAH’s, Pharmaceuticals, PCP’s, PCB’s, Dioxins, Furans, PBDE’s, Analgesics and Stimulants
such as caffeine.

 

C.L.A.M. Replacement Parts Kit
This is a general replacement kit for C.L.A.M. parts and is a good backup to have when you’re working in the field. It includes one calibration syringe, two rubber battery housing sealing gaskets, one battery holder, three foot length of 1/8 inch calibrating tubing and two Luer lock adapters threaded and one Luer lock quick connect.
