Entech’s turn-key solution to soil gas sampling – designed with you in mind. Our Chameleon Soil Gas Sampler provides an all-in-one solution that will challenge the standards of soil gas studies worldwide.

Nickel ferrules seal and are easily replaceable just like Graphite-Vespel^TM ferrules, yet just like stainless steel ferrules, they are also non-contaminating and cannot be removed by hand.

The internal Silonite^TM coated sealing spring in a MicroValve^TM is stronger than those used in Swagelok® Miniature Quick Connects, to further reduce the potential for leaks even at cold storage temperatures (-15°C). A compression fitting cap is also available, which when used with the MicroValve^TM creates a lower combined leak rate than any other currently accepted canister valve.

MiniCans^TM are the next generation of air sampling canisters from Entech. Designed for tool-free operation and advanced robotic analyzers, Silonite^TM treated MiniCans^TM allow the recovery of a wider range of compounds than any other sampling canister – including semi-volatiles up through the full diesel range and C25 hydrocarbons.

The 1900 Multi-Channel Canister Sampler is Entech’s next generation solution for collecting air samples in Silonite^TM coated canisters for detailed analysis in the laboratory by GC/MS or GC/FID/MS. A dramatically improved flow path now creates far less potential for carryover relative to other commercially available samplers

The TM1200 is Entech’s next generation canister sampling timer that automatically starts and stops the sampling process at specific times. Now you can easily start a 24 hour sample at midnight and stop it at midnight the following night without having to be present. Typically operated with our CS1200Ex canister sampler to time integrate the sampling event for a 24 hour sample, the TM1200 creates an optimized solution by exposing the collected sample to a very short, inert flow path for maximum compound recovery and minimal carryover.

We are the only manufacturer to offer the unsurpassed range, quality, and reliability of McDaniel Controls, Inc. gauges along with our exclusive, ¼” compression canister / TOV^TM fitting design. ­ The compression fitting connects easily to a dual stem canister, or our new dual port TOV^TM without any need for Teflon® tape!

Low-Level TO-15 monitoring requires consistent analyte recovery while collecting the maximum sample volume possible to support larger preconcentration volumes or repeat analyses from the same canister. The CS1200E will reliably fill canisters at a constant rate with a better-demonstrated recovery of TO-15 compounds than any other sampler.

Introducing Entech’s breakthrough technology for whole air sample collection – Helium Diffusion Sampling (HDS^TM). We now offer HDS^TM active sampling solutions for indoor air monitoring that simplify the collection of airborne chemicals for GC and GC/MS analysis. Rather than performing a traditional vacuum sampling event, MiniCans and Bottle-Vacs^TM are initially filled with helium, or helium with a recovery surrogate, and active sampling occurs in response to the controlled exchange of helium with air through a diffusion region.

Performing unfiltered sampling into your Silonite^TM canister can lead to particulate contamination. This will eventually reduce volatile compound recovery while making it more difficult to achieve EPA required blank levels. Entech’s Grab Samplers are a great solution to keep your canisters clean.

In the laboratory, analysis by loop injection requires either pressurizing to 3–7psig, or heating to 60–70°C to increase the pressure to purge a loop. Bottle-Vac^TM samplers can also be analyzed using the 7200A or 7100A Preconcentrator to withdraw a larger volume for low PPB analysis. Automated analysis can be performed using the 7650, 7410D, or 7032A Autosamplers.

The TOV-2^TM Toxic Organics Valve has been specifically designed to ensure complete recovery of low-level TO-14a and TO-15 target compounds. A pack less system features an ultra-compact, passivated sample path with no internal weld scars, and a Silonite^TM coating option for superior inertness and durability.

The FlowProfessor^TM automatically adjusts the flow setting of the CS1200E to obtain the correct flow every time. The sophisticated software even adjusts for estimated field temperatures and sampling site elevation to optimize sampling rates under any environmental condition. Trying to accomplish those calculations manually can be difficult at best.

Entech has engineered a new “twist” in whole air monitoring that eliminates many of the potential sources of error found in other sampling methods. Unlike other monitoring approaches such as tubes and badges, the new HDS^TM Monitor enables compounds to remain in the gas phase where chemicals are much less likely to interact.

The IH1200 Personal Monitors utilize classical vacuum sampling into MiniCans^TM and Bottle-Vacs^TM to perform STEL or TWA monitoring for up to 12 hours. Like HDS Personal Monitors, sampling using the IH1200 eliminates the concentration and matrix effects associated with adsorbent-based sampling techniques.

Introducing Entech’s low-cost external HDS^TM Samplers that allow any Silonite^TM Canister or Bottle-Vac^TM to be used to perform time-integrated sampling both simply and cost-effectively. HDS^TM utilizes a simple diffusion zone to control the exchange rate of helium and air, with diameters that are 20–50 times larger than typical critical orifice samplers.
