7200A & 7200CTS Preconcentrators
Concentrate volatile compounds from air and gas samples before GC-MS analysis. The 7200A uses cryogenic trapping for accelerated canister analysis, while the 7200CTS offers cryogen-free multi-capillary column trapping. Select the platform for your target compounds and method.
Silonite™ Sampling Canisters
Collect whole-air samples for VOC analysis using internally coated canisters. Entech’s Silonite coating and inert sampling valves support sample storage and recovery. A range of canister sizes serves ambient air, indoor air, soil gas and vapour intrusion workflows.
CS1200E Sampling Flow Controller
Control the collection of time-integrated air samples into evacuated canisters. The CS1200E combines an inert flow path with tool-free connection options and adjustable sampling flow for different canister sizes and sampling periods.
3200 Canister Cleaning Systems
Prepare canisters for reuse through automated evacuation and refill cycles with nitrogen or zero air. The 3200 controller works with 3208 and 3212 ovens and manifold options for different canister sizes and laboratory throughput.
VASE™ Headspace Extraction
Vacuum Assisted Sorbent Extraction collects headspace compounds on Sorbent Pens for thermal desorption and GC-MS analysis. Applications include VOCs and SVOCs in water, soil, foods, beverages and consumer products, including aroma and off-flavour investigations.
AirDiscovery™ Thermal Desorption
An automated GC-MS introduction platform for air monitoring with active and diffusive Sorbent Pens. Direct thermal desorption and capillary focusing support workflows for volatile and semi-volatile organics in ambient, indoor, workplace and fenceline air.

From sampling to GC-MS
Tell SAMSI your sample matrix, target compounds, concentration range, sampling duration and analytical method. We can help identify a suitable combination of sampling devices, preparation equipment and GC-MS introduction options.
Typical application areas include air quality monitoring, soil gas and vapour intrusion, industrial hygiene, food and beverage aromas, off-flavours and product emissions.
