The world’s only GC-MS process analyzer!
Neutrino expands the Eclipse platform with the ability to reach lower detection limits with unparalleled identification accuracy. Combining the separation of gas chromatography with the identification power an Agilent 5977B mass spectrometer, Neutrino allows users to detect and quantify components that would be impossible with other detectors.
The Wasson-ECE Neutrino combines the capillary chromatography capabilities of the Eclipse Process Analyzer with the powerful mass selective detector (MSD) to provide positive identification and quantification of impurities in process samples. The Neutrino supports configuration with additional detectors, including FID, TCD, and PDHID, enabling comprehensive multi-component analysis within a single analyzer platform.
The Neutrino accommodates process analysis of samples that previously required laboratory testing, delivering accelerated feedback and enhanced operational efficiency for process control.
Wasson-ECE possesses extensive expertise in configuring GC-MS systems for diverse and challenging applications. The Neutrino incorporates the same Agilent MSD technology utilized in laboratory applications, ensuring seamless transition to process analysis.
Neutrino is the world’s only GC-MS process analyzer. The MSD is capable of trace analysis and positive identification of a wide range of components. The Micro-Convection oven provides precise temperature controls essential for laboratory-quality capillary column chromatography, while Wasson-ECE’s valve chromatography expertise enables unparalleled process analysis capabilities.

The only on-line process VUV (Vacuum Ultraviolet) analyzer.
Wasson-ECE has the world-wide exclusive ability to bring vacuum ultraviolet spectroscopy to process GC. VUV is a universal detector delivering unique spectral signatures of compounds. When coupled with GC retention time data, this combination allows for detailed characterization of hydrocarbon mixtures (PIONA, ASTM D8071 and much more). Eclipse-VUV can be designed for both Class 1 Division 2 and ATEX Zone 2 rated areas.
Acquiring detailed composition of fuel products in real-time on the process line allows for rapid response to process disruptions.
Built on decades of Wasson-ECE expertise in laboratory and process analytics, the Eclipse Analyzer bridges the gap between laboratory precision and process requirements. Wasson-ECE has been using the VUV analyzer for laboratory applications for over 7 years. Using the same VUV and incorporating it into our process instrumentation allow for the seamless transition of applications, already proven in the lab, to be brought out into process environment.
Eclipse-VUV is the only online VUV process analyzer. The VUV allows for the detailed composition of liquid fuel products, verified by spectral analysis. Along with Wasson-ECE process instrumentation hardware including micro-convection ovens, capillary columns and electronic pressure controls, the instrument provides repeatable, accurate and detailed breakdown of liquid fuel products.

Xylenes provide an excellent example of the power of VUV to differentiate between very similar coeluting compounds. Xylene isomers co-elute chromatographically (A) but exhibit spectroscopically distinct features when scanned between 120-240nm (B). VUV deconvolution algorithms use these features to correctly match the isomers to the reference spectra in the compound library.
