  • An Exhaust Solution for Controlled Environments
    : exhaust from laboratory workstation fume hoods or other procedure/processing areas must be safely discharged into the atmosphere without causing re-entrainment, creating an odor problem or violating environmental regulations. . This quick, one-time registration gives you access to members-only site
  • An Exhaust Solution for Controlled Environments
    that extract heat from workstation fume hood exhaust before it is discharged above the roofline. The warm air from the heat exchanger is transferred to the supply-side handler to preheat the conditioned air entering the building, thus reducing the amount of natural gas or fuel oil needed to heat
  • The Development of a RTD Temperature Sensor for Exhaust Applications (.pdf)
    A RTD (resistive temperature device) high temperature sensor was developed for exhaust gas temperature measurement. Extensive modeling and optimization was used to supplement testing in development. The sensor was developed to be capable of withstanding harsh environments (-40?? to 1000??C

  • Eliminating Laboratory Fume Hood Exhaust Re-Entrainment: How Wind Studies Helped Assure a Successful Project
    AS A PRIME. CONSIDERATION. Since facility safety was a fun-. damental requirement, "all means. available," according to Wilson,. were employed to prevent exhaust. re-entrainment into the building.

  • QIC-Biostream - Exhaust gas analysis of small scale fermenters
    . Exhaust gas analysis of small scale fermenters. Summary. The application of the Hiden QIC-Biostream gas. analysis system is to monitor the off-gas and. vapours from up to 80 small scale fermenters for. yield optimisation and process screening. Introduction. Biotechnology is an extremely important area
  • Detection of Nitroarenes in Diesel Exhaust Using HPLC with UV and Fluorescence Detection
    A family of polyaromatic hydrocarbons (PAHs) known as nitroarenes are present in automobile exhaust. These species are known to be highly mutagenic and carcinogenic. Thus, it is very important to develop good methods for the analysis of these species. In many cases the presence of interfering
