  • High-sensitivity, fast-response monitoring of PFC and abatement tool emissions by FTIR spectroscopy

    Semiconductor fab plants are faced with real-time monitoring and reduction of their PFC emissions to meet SEMI Environmental, Health and Safety (EHS) requirements. In some cases emissions are continuous, while in other cases they are intermittent or random. Also, in-situ real-time process control is becoming a critical element of yield enhacement. Solution: FTIR Spectroscopy In-Situ ...

  • ppb Dissolved oxygen measurement

    Dissolved oxygen (D.O.) measurement is one indicator of water quality because oxygen is a common element contributing to corrosion reactions. This corrosion reaction provides the need for low level D.O. control since dissolved oxygen is responsible for costly replacement of piping and equipment by corrosive attack on metah. what is Dissolved Oxygen? Dissolved axygan (D.O.f is the ...

  • Measurement of moisture in HBr

    Introduction Moisture in corrosive gases will accelerate the rate of metal corrosion in gas supply systems which, in turn, can lead to their premature failure. For this reason, it is important to monitor moisture levels in these gases. FTIR is an effective way to monitor for moisture in these corrosive gases. In order to determine low levels of moisture in corrosive gases, it is ...

  • Detecting Gases: What You Can`t Smell Can Hurt You

    Walking through a drill-site area, a worker smells rotten eggs and stops tor a minute or two to assess where a gas leak might exist. Rubbing his itchv eves as he investigates further, he notices that he no longer smells the tell¬tale hydrogen sulphide odour. He does not realize that the gas has deadened his olfactory senses and unless he leaves the area within seconds, he could lose ...

  • Quadrasperse Quadpolymer solves major fouling problem at large Gulf Coast Petrochemical Plant

    Background As a result of poor results with a previous water treatment supplier, ChemTreat was given the opportunity to turn things around in a large, open recirculating cooling system for a Gulf Coast chemical plant. The cooling system serviced a light olefins unit with multiplestage, cracked-gas compressor after-coolers operating at a high skin temperature. At a maximum skin temperature of ...
