Protea Limited

Measurement solution for organic vapour speciation - Monitoring and Testing

Protea has deployed FTIR gas analysers in many projects requiring the monitoring of complex mixes of VOCs. In the chemical and pharmaceutical industry, scrubbers and carbon-bed abatement plants are typical installations where the use of Protea FTIR analysers and our chemometric expertise have proved valuable to plant operators. They prove an invaluable tool in process measurements and emissions monitoring. In the laboratory, Protea can deliver instruments with all the chemometric software and support to enable users to measure hundreds of gases.

Typical organic speciation measurements include:

  • Alkenes: Linear (Methane, Ethane, Propane, n-Butane, Pentane, Hexane, Heptane, Octane), Branched (Iso-butane, Iso-octane) and Cyclic (Cyclopropane, Cyclobutane, Cyclopentane, Cyclohexane, Cycloheptane)
  • Alkenes: Ethylene, Propylene, Butylene
  • Alcohols: Methanol, Ethanol, 1-Propanol, 2-Propanol (Isopropyl Alcohol, IPA), n-Butanol, Iso-butanol, sec-Butanol, tert-Butanol
  • Ketones: Acetone, Methyl Ethyl Ketone (MEK), Methyl Isobutyl Ketone (MIBK), Diethyl Ketone, Methyl Vinyl Ketone
  • Aldehydes: Formaldehyde, Acetaldehyde, Butyraldehyde, Benzaldehyde
  • Esters: Methyl Acetate, Ethyl Acetate, Ethyl Butyrate, Ethyl Formate, n-Butyl Acetate, Isobutyl Acetate, Isopropyl Acetate
  • Ethers: Ethylene Oxide, Dimethyl Ether, Di-isopropyl Ether, Diethyl Ether, Methyl Tert-butyl Ether, Tetrahydrofuran (THF)
  • Carboxylic Acids: Formic Acid, Acetic Acid, Propionic Acid, Acrylic Acid, Butyric Acid
  • Aromatic: Benzene, Bromobenzene, Fluorobenzene, Iso-propyl Benzene, Ethyl Benzene, m-Xylene, o-Xylene, p-Xylene, Mixed Xylenes, Toluene, Styrene
  • Amines: Methylamine, Diethyl Amine, Triethylamine, Butylamine, Dibutylamine, Tributylamine
  • Amides: Formamide, Acetamide, Dimethyl Acetamide, Dimethyl Formamide (DMF)
  • Alkynes: Acetylene (Ethyne)
  • Halogenated Organic Species: Chloromethane, Dichloromethane (DCM), Chloroform, Chloroethane, Carbon Tetrachloride, Trichloroethylene, Tetrachloroethylene, Chlorobenzene

Protea can deliver analysers for use either as transportable or fixed industrial monitoring systems, giving plant operators or emissions testers the powerful capabilities of FTIR is easy to deploy packages. For the trained FTIR user in the lab or the field, full spectrum libraries and model building software allow analysers to be configure and re-configured again and again to measure an almost infinite range of gas applications.
