Coated Bolt SPME Self Sealing Water Sampler for Manual and ROV Assisted Analyses of Harsh Environments such as Hydrothermal Vents
Overview:
- A set of durable, self-sealing and chemically resistive water samplers were developed which employed a sorbent (HLB/PAN) coated rod as a structural support and SPME material
- The coated screw design employs a spring that automatically forces the device shut, keeping the sorbent coating sealed in the Teflon body during transportation and stabilizing extracted compounds on the coating
- The large surface area of the screw allows for good sensitivity even when shorter extraction times have used a total of 6 screws per sampler allows for simultaneous replicate sampling both a diver and submersible ROV operable variant of the sampling device have been designed and successfully deployed.
