Model: Shepherd FTIR
Manufacturer: Cerex
Portable FTIR Multi-gas Analyzer
Continuous, real time portable monitoring of 385 individual species of gas: 100+ HAPs, Acids, VOCs, SVOCs, Fluorocarbons, CFCs, Solvents, Hydrocarbons, Combustion Gases, Organics.
Fully Portable
The Shepherd FTIR utilizes an ultra-sensitive cryo-cooled MCT detector system for sensing minute changes in IR absorption due to the presence of trace concentrations of individual gases. The result of coupling our proven detection system with a 20 meter internal optical sample path and CMS real time analytic software is an industry leading FTIR multi-gas analyzer. Offering true ppb detection limits in a simple to operate portable package, in practice, only the Cerex cryo-cooled system can reliably deliver unattended, continuous real time monitoring of ultra low ppb concentrations of individual gas species with absorption features spanning the IR spectrum from 2 to 14 microns. There are no additional costs for sample handling, wet chemistry, carrier gas , sorbent filters or tedious ongoing calibrations. There are none of the constant maintenance costs or extra work associated with the handling of, or regulatory compliance issues arising from the use of liquid nitrogen coolant. Results are immediate, and the raw data containing all the information necessary for gas identification and quantification is always saved. Low cost of ownership is achieved through a three year routine maintenance cycle.
Features
For twenty years Cerex has manufactured the premier open path FTIR analyzer: Our AirSentry FTIR. With so many installations among diverse users worldwide, Cerex has received high quality feedback from Industry, Government, Engineers, Operators, Systems Integrators and Scientists operating our FTIR analyzers. We listened—The Shepherd FTIR offers features and a variety of configurations for flexible operations. An internal cell, long life consumables, a simple user interface, simplified networking and unknown gas analysis software.
The touchscreen interface, intuitive controls, large buttons, multiple analysis routines, advanced signal smoothing and low ppb detection limits make the Shepherd FTIR ready to meet a broad spectrum of monitoring requirements, with the flexibility to meet the needs of field technicians as well scientists.
