Wasson-ECE Instrumentation products

The Variable Pressure Sample System (VPS) gives you two ways to ensure the precision and accuracy of your gas chromatography results. The first method is pressure correction, used to create uniform pressure among all injected samples and calibration blends. The second method is multipoint calibration, which you can use to test the pressure ranges that will deliver accurate results from your calibration blend.

The Wasson-ECE Dynamic Blender is a simple, portable blending device that dilutes a sample or certified standard with a diluent gas of choice. The device contains a digital mass flow controller (MFC) that allows the diluent gas flow to be easily adjusted. An inert flow path and heated bridge eliminate adsorption and condensation issues when blending gas standards that include sulfurs, oxygenates, or other reactive analytes. The diluted mix is fed directly to a gas chromatograph (GC) sampling loop for analysis. Gas chromatographic analyses often require multi-level calibration or low concentration standards. Some analytes are quite expensive or difficult to purchase at low levels due to reactivity, adsorption, or high molecular weights.

The Wasson-ECE Liquid Auto-sampler (LS100B) automates the delivery of pressurized liquid samples such as liquefied petroleum gas (LPG) and natural gas liquids (NGL) to a gas chromatograph (GC) for analysis. The auto-sampler accommodates up to nine unheated sample cylinders with maximum pressure of 1000 psig. The system uses an inert gas to maintain pressure ensuring samples remain in liquid phase for analysis.

The Wasson-ECE LPG Pressurization Station is a stand-alone unit that prevents premature evaporation of liquefied petroleum gas (LPG) samples such as C3 and C4 hydrocarbon mixtures. The system is designed with a user adjustable pressure regulator, a back-pressure restrictor, and a sample relief valve to maintain sample integrity for reproducible LPG injections.

The capabilities of a gas chromatograph (GC) are unmatched in analytical chemistry. Unfortunately, a GC is a complex device with a lot of parts that need to work in harmony to correctly perform the analysis you’re after. GC’s are typically sold as “vanilla boxes” and the component selection and method development are all left up to you. You must do your homework to select the appropriate parts and add-ons.

With Eclipse, Wasson-ECE is leading the revolution in process gas chromatography. Eclipse analyzers are fully customizable to meet the needs of the most challenging processes.

The Wasson-ECE Non-Volatile Organics Concentrator (NVOC) accommodates the sampling of heavy organic contaminants, such as ethylene glycol and pump oil, in liquid carbon dioxide. These heavy components can be found in carbon dioxide due to leaks in pump seals or other equipment.

The Wasson-ECE OFID Controller Box with Purge Pressure Shutdown is a stand-alone accessory for Wasson-ECE OFID analyzers to prevent damage to the OFID cracking reactor caused by loss of reactor purge gas. The OFID/methanizer controller box is designed to shut down the heater of the OFID cracker upon loss of purge gas. When purge pressure is lost, power to the OFID heater will be shut down and an LED will illuminate to indicate loss of purge. When purge pressure is reestablished, the LED will turn off and a timer LED will illuminate. Power is restored to the OFID heater circuit once the reactor has properly purged. The system contains a timer bypass button to allow the user to bypass the purge timer.

The TO-Clean canister cleaner allows for fully automated canister cleaning. The TO-14/15 compliant TO-Clean system was designed to take the guesswork out of canister cleaning. The twelve 6-litre canister capacity will increase your lab`s efficiency. The system is fully automated, allowing the user to start a cleaning cycle and walk away. Using the touch screen controller, up to ten methods can be defined and loaded as needed. The system also comes with an automated leak check method to ensure system performance. This provides a high performance system that is easy to use as well as consistent.
