Cambridge Sulfur hexafluoride humidity analyzer

Cambridge Sulfur hexafluoride humidity analyzer

Sulfur hexafluoride is primarily of anthropogenic origin but also occurs naturally in minerals, rocks, and volcanic and igneous fluids. Concentrations of SF 6 in air have rapidly increased from a steady state value of about 0.02-0.05 to over 7 parts per trillion during the past 40 years, and are expected to continue increasing.

  • Measurement of methane emission from sheep - Cambridge Core

    Abstract. The aim of this study was to evaluate the sulphur hexafluoride (SF 6) tracer technique for methane (CH 4) emission measurement in sheep. Ten cryptorchid Romney sheep were involved in two indoor trials (T 1 and T 2 ), where daily CH 4 emissions were individually measured both by the SF 6 tracer (‘tracer CH 4 ’) and by the indirect calorimetry chamber (‘chamber CH 4 ’) techniques while fed on lucerne hay at 1.2 times maintenance requirements.

  • Comparison of the sulfur hexafluoride tracer and respiration

    Jun 01, 2012 · A technique that makes use of the inert tracer gas sulfur hexafluoride (SF6) has been developed for estimating CH 4 emission rates from ruminants under grazing conditions (Johnson et al., 1994). In recent years, some studies have examined the validity of the SF 6 tracer technique for estimating CH4 emissions.
