Total quantity or scope: The University of East Anglia is looking to purchase a versatile field-deployable GC-Time-of-Flight mass spectrometer (GC-ToF-MS) system for ultra-trace environmental air, water and soil analysis of volatile compounds (boiling point range -140 AC to 300 AC) such as halocarbons
(including iodocarbons, bromocarbons, chlorocarbons, CFCs), sulphur gases (including dimethyl sulphide and carbonyl sulphide), oxygenated and nitrogenated hydrocarbons (including short-chain alcohols, aldehydes, and ketones, alkyl nitrates, and acetonitrile), persistent organic pollutants, primary, secondary and tertiary amines.
extracted during the recycling process are shipped to the U.
Ramanathan's studies on the climate warming effects of non-CO2 pollutants dates back to 1975, when he discovered the super greenhouse effect of a class of halocarbons
known as chlorofluorocarbons (CFCs).
in butter: Elevated tetrachloroethylene levels in samples obtained in close proximity to dry-cleaning establishments.
Their molecular structures include a very wide range of individual substances, such as hydrocarbons, halocarbons
and oxygenates, which are very harmful to the environment and human health.
manufacturers of residential refrigerators currently use non-chlorine containing halocarbons
(HFCs) as blowing agents for rigid polyurethane insulating foam.
When it comes to other gases, the combined radiative forcing by halocarbons
Other greenhouse gases include halocarbons
that contribute 12 per cent of the global radiative forcing.
Several classes of halocarbons
containing fluorine, chlorine, and
The newly constructed 30,000 square foot facility is part of a three-phase program to contain and manage Class I and II Ozone Depleting Substances (ODS) and other halocarbons
Critical evaluation of sampling and gas chromatographic analysis of halocarbons
and other organic air pollutants.
