Analysis of High Pressure Samples by Gas Chromatography
High molecular weight compounds dissolved in gases at elevated pressures and temperatures in reservoirs often present production problems. These can range ftom precipitation of solids which foul chillers and tubing to plasticizing membranes used for gas component separations. Quantitative analysis of such samples is problematic because they are frequently present in sample vessels as two phases...
متن کاملLow Pressure - Gas Chromatography : Recent Trends and Developments
25 Low pressure-gas chromatography (LP-GC) has been applied during the last few 26 years for the fast analysis of various pollutants in different environmental and food matrices. 27 A typical LP-GC setup involves the use of a short microbore column (typically 0.5-1 m x 28 0.10 mm internal diameter) at the injector side connected with a zero dead-volume connector 29 to a short megabore column (t...

متن کاملInspiration by Magellanic penguins: reduced swimming effort when under pressure
Some marine mammals may increase their underwater locomotor efficiency by taking down little air for dives and descending passively, although at the point of maximum depth they presumably have to use energy to counteract the downthrust, to stop themselves sinking further. Birds, having considerable quantities of body-associated air, would appear not to have this option. However, measurements of...
