Entech HDSTM Personal Monitors
Introducing the latest HDSTM (Helium Diffusion Sampling) Personal Monitor from Entech. A breakthrough technology based on helium diffusion yields a sampler that is small, light weight, cost-effective, universal, and defensible. HDSTM Personal Monitors simplify the collection of chemicals in the workplace and deliver highly reliable results unaffected by factors that create errors in other diffusive samplers – such as matrix concentrations, varying humidities, and fluctuating face velocities.
CS1200E Passive Canister Sampler
The CS1200E is a high-purity flow regulation system designed to reliably fill canisters at a constant rate from vacuum to within 1 psi of atmospheric pressure without requiring any power. Unsurpassed flow path inertness and a newly revised flow design enhances TO-15 compound recovery while improving flow stability. No other sampler has scientific data supporting the […]
7650HS-CTS Large Volume Static Headspace Brochure
The 7650HS-CTS is Entech’s latest GCMS headspace sample preparation system that recovers a wider range of compounds at lower concentrations than any other headspace system. The 7650HS-CTS supports sample analysis via large and small volume static headspace (1-1000cc) to accommodate a wide range of concentrations with quantitative recovery of compounds with boiling points from -70C […]
7650 Canister Autosampler
The 7650 brings the automated analysis of MiniCansTM, Bottle-VacsTM, and even large volume sampling canisters to a whole new level. Drawing upon the benefits of its predecessors, the 7650 is the first canister autosampler to facilitate the analysis of up to twenty, 1 to 1.4L canisters while maintaining samples in a completely closed and isolated […]
7200 Preconcentrator
The 7200 takes the industry standard, 7100A’s 3-stage preconcentration and water management technology, and elevates it to a whole new level. Many of the past limitations often seen in rotary valve based devices are now eliminated by combining digital valve isolation control with advanced robotic autosamplers, dropping the potential for carryover and cross-contamination far below […]
7032A Autosampling System
The 7032A Autosampler automates the introduction of up to 21 MiniCans, Bottle-Vacs, or Tedlar® bags into the 7200 for preconcentration. The 7032A is ideal for gas-phase volatiles applications where concentrations are expected to be within 0.2 PPB to 500 PPB. For higher concentrations, a loop injection valve can be installed (7032AQ-L, 7032AB-L) to allow much […]
7016D Autosampler
The new 7016D features 16 inlet positions that bring Entech’s automated analysis capabilities to a wide variety of vacuum sampling canisters and Tedlar® bags. The 7016D quickly connects to a 7200 Volatiles Preconcentrator for automated analysis of VOCs in canisters to comply with EPA Toxic Organics Methods TO-14A and TO-15.
5400B Thermal Transfer System
The analysis of adsorbent tubes can be a nightmare for analytical laboratories, especially when there is a requirement to get results on 100% of the tubes tested. Instrument problems, unexpected analyte loading outside of the GCMS calibrated range, and cross-contamination make the normal “one-shot” analysis very risky. Even attempting to recover a “split” fraction of […]
4700 Precision Diluter
The 6 Channel 4700 Precision Diluter represents the next generation in accurate canister standards preparation. Utilizing a combination of precise gas flow control, exact pressure measurements, and an ultra-inert flow path, the 4700 is capable of performing multistage dilutions for achieving standards ranging from part-per-billion to low part-per-trillion. The 4700 works with canisters and Bottle-VacsTM […]
Entech 3100D, 3108D, 3112D Canister Cleaning Systems
Canisters are cleaned for reuse by evacuating and refilling with nitrogen or zero air multiple times to completely eliminate VOCs introduced during the previous sampling. After cleaning, canisters are left under vacuum in preparation for re-sampling. System pressure and vacuum readings control the evacuation and fill times to create consistent batch to batch cleaning. Silonite™ […]
