The probe is driven into the ground by a hammer. The core is collected inside the core-barrel chamber within the lower half of the probe. The probe is lifted 4 inches, opening a hidden compartment that channels the ground water into a water canister through Teflon straws located in the grooved edges running along the length of the core-barrel. The water canister is closed by back pressurization, and prevents the escape of VOC’s while the probe is removed from the exploratory borehole. At the surface the soil core and groundwater sample can be easily removed from the SimulProbe for shipment to a laboratory. Benefits to using the SimulProbe for soil and groundwater sampling include: Representative sampling. Soil core and water sample are taken at the same place. (Can also be used for simultaneous soil core and soil vapor.) Time savings. Quick setup and mobilization. VOC measurement. Back pressurization keeps VOC’s in groundwater sample and provides higher accuracy laboratory results. Overview of simulprobe technology for simultaneous soil and gas sampling BESST’s SimulProbe is used in exploratory borehole drilling to collect a simultaneous soil core and soil gas sample. The probe is driven into the ground by a hammer. The soil is driven inside the core-barrel. The probe is lifted two inches, opening a hidden compartment that channels the soil gas into the probe through two Teflon straws located in the split half grooves that run along the edges of the core barrel. A vacuum pump is connected to a tube running from the probe to the surface. The vacuum pump is used to collect the gas directly from the soil. Once the gas sample has been collected using a Tedlar bag, Suma Canister or Soil Gas Syringe, the probe can be removed from the borehole and the soil core sample can be easily removed from the SimulProbe for shipment to a laboratory. Benefits to using the SimulProbe technology for simultaneous soil and gas sampling include: Representative sampling: Soil core and soil gas sample are taken at the same place. VOC measurement: The VOC’s are directly collected from the ground which limits cross contamination of sample. Time savings: Quick setup and mobilization. System can be used with photoionization detector (PID) for on-site results. In-Situ Head Space Test: Enhances accuracy of on-site field measurements by directly sampling the soil-gas downhole, rather than using unreliable ex-situ methods which damage sample integrity. · © 2018 All rights reserved BESST, Inc. ·
