Portable & Fixed Site Chemical Detection & Monitoring OwlSens-T is the first of its kind, next generation, gaseous and volatile chemical monitor. Capable of detecting more chemicals than any other single detector, OwlSens-T's key features include: - EXTREME SENSITIVITY – Detection limits to parts-per-billion - SELECTIVITY – Exceptional ability to resolve similar chemical compounds - RAPID RESPONSE – 15 second detection; 60 second identification - REPROGRAMMABILITY – PC controller for simple software updates and higher level data interpretation - VERSATILITY – capability against most gaseous/volatile chemicals listed in NIOSH 2010-168C (Pocket Guide to Chemical Hazards) Example deployments - Industrial hygiene - In-plant air monitoring - Distributed pipe network - Leak detection - Clean room monitoring - Process monitoring - Chemical storage tank integrity Broadband detection - Corrosive acidic gases (e.g. SO2, HCN, HF, H2S) - Corrosive basic gases / vapors (e.g. NH3 & Amines) - Halogens (e.g. F2, Cl2, PCl3, PF3) - VOCs (e.g. ethylene oxide, acrolein, acrylonitrile, etc.) - Halocarbons (e.g. vinyl chloride, CFC's, etc) The Technology OwlSens-T utilizes a highly advanced variant of Ion Mobility Spectrometry (IMS). This new method of ultra-fast chemical separation exploits the unique thermal properties of an ionized chemical sample, in a rapidly modulated high electric field. Every chemical has a unique spectral “finger-print”, which enables real-time identification and quantification from an on-board data base. OwlSens-T technology delivers an analytical detection window greater than double that of other Ion Mobility based separation systems; allowing greatly improved chemical separation and identification. Multi-dimensional datasets are generated and automatically analyzed, on single-second timescales, resulting in faster, more accurate, low-false-alarm rate detection and quantification.

A diffusion tube is a container with an opening at the top (which may be covered with a permeable membrane). Gas evaporates from a reservoir of sample at the bottom of the tube, and diffuses upwards at a rate governed by temperature, pressure and tube geometry. Performance Comparison: - Can be used with the V-OVG - Any substance with a sufficiently high vapor pressure can be used - Can produce higher concentrations

The GEN-SYS is a modified 19” rack unit especially design to houses a series of instruments that provide the functionality and adaptability needed to create a wide range of vapour standards. As the system is based on a modular design the user has a choice of when and what modules they wish to employ, the choices of modules are the OVG-4, OVG-4C, OFC-1 and OHG-4. GEN-SYS is designed to create chemical vapours, therefore to limit the user’s exposure to these chemical vapours it is strongly recommended that the GEN-SYS be operated in a fume hood, or ideally in a well-ventilated space. Do not place in the following environments - Space that is poorly ventilated or confined. Allow at least 50cm clearance from walls and free flow of air around the system - Locations with an ambient temperature above 30 oC- Locations where the altitude is greater than 10,000 feet. - Do not place the unit on fabric or any other soft surface - Do not cover the unit with a cloth or any other item - Do not place near flammable materials - Where maximum relative humidity exceeds 80 % GEN-SYS is supplied with a power supply that is automatically compatible with all conventional mains power supplies: 100-240V, 50-60Hz, max 2.5A. It is not necessary to manually select or switch voltages. The maximum power consumption of GEN-SYS is 170 W. The Power supply comes with a 5A IEC mains lead for the UK, or a European / USA equivalent. Warning if power is interrupted to unit this will result in an increase in concentration of vapour levels. If unit found in a powered down state it is suggested to purge the permeation oven by opening the split flow fully for 2 hours. GEN-SYS requires a pressure regulated supply of air / nitrogen at 40 psi. As the GEN-SYS is primarily used to validate instrument detection capabilities it is recommend that the gas supply has a dew point lower then -35 0C, is free from impurities (Hydrocarbon less than 0.1ppm methane) and particulates (less then 30 μm). It is also recommended that all gas lines be constructed of refrigeration grade copper or stainless steel tubing connected using Swagelok fittings. Please note that if the gas supply is interrupted whilst a permeation source is being incubated within the OVG, the concentration of the chemical will increase until it has reached a saturated level. For this reason any interruptions in the gas supply will result in a flow controller alarm where the permeation oven will be turned off. If found in this state please purge the oven through the exhaust with the sample outlet closed. A separate exhaust line off ¼” OD and 2 meters in length should be made ready to connect to the exhaust outlet of the GEN-SYS. This line should be checked for chemical compatibility and it is recommended that it is exhausted to a fume hood. Check the exhaust line at regular intervals for blockages and leaks. • Check chemical compatibility: Materials in the flow path include PTFE, copper, stainless steel, and Viton®. Ensure permeation devices are neither corrosive nor reactive with materials in the flow path. • Always refer to the Material Safety Data Sheets relevant to the vapour(s) you are handling and ensure adequate risk controls and COSHH are in place before using potentially hazardous vapours / gases with the GEN-SYS. • The GEN-SYS racking unit gets warm during operation, especially the oven inlets. • Do not place liquids on or near the GEN-SYS. Liquid spill may cause instrument failure. • Ensure cabling is routed behind the system, at bench level, posing no risk of tripping. Ensure that all cables are detached from GEN-SYS before attempting to move the unit. • GEN-SYS has not been designed for drop tests; any such test or accidental drop will cause damage to the system. • The GEN-SYS rack unit can weigh up to 25kg please take care in handling to avoid injury.

The Vertical Owlstone Vapor Generator (V-OVG) is designed to be compatible with both permeation tubes and diffusion tubes.
CATEGORY
The Owlstone V-OVG is a system for generating precise, repeatable trace concentrations of gases. By using permeation and diffusion tube technology, a range of concentrations from low parts per billion to high parts per million levels can be achieved. The large permeation oven allows the use of up to 6 permeation tubes to create multiple-component mixtures, or a diffusion tube to generate high ppm concentrations.
