GCMS Inlet for Detection and Characterization of “Aroma Significant Compounds” in Foods and Beverages
Accurate Monitoring of Sulfur Compounds in Silonite® Fused Silica Lined Canisters Utilizing a New Approach for Water Removal During Field Sampling
Flavors, Odors, and Contaminants in Alcoholic Beverages using Vacuum Assisted Sorbent Extraction (VASE) and GC/MS Analysis
Quantitative Headspace Measurement of Volatiles in Dairy Products using Vacuum Assisted Sorbent Extraction (VASE) & GCMS Analysis
Improved Performance And Dynamic Range For EPA Method TO-15 using the Entech 7200 and Agilent 7890B/5977 GCMS
Canister sampling and analysis for measurement of volatile chemicals is finding use in a growing number of diversified applications. This has required air laboratories to accommodate an even wider dynamic range of sample concentrations, and a growing list of compounds to include those once thought to be incompatible with canister sampling techniques.
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.
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 […]
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 […]
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 […]
