Stall Packing

The principle of the stall packing method is to fix the final bed height of the column

After we ve helped Morgan take down her stall and pack her stock into the boot of the car, it seems natural to go to the pub. It s full of other market people as well as locals and a tourist or two. We... 

Owing to their greater exposure to motor vehicle exhaust emissions, it is possible that fatty foods on sale at shops attached to petrol stations or at stalls and shops in busy roads could contain higher concentrations of aromatic hydrocarbons than similar foods on sale at other shops. A study in Germany found that concentrations of benzene and toluene were higher in retail packs from petrol stations on busy roads than from petrol stations in rural areas.15 It also found that retail packs from shops in busy roads contained higher concentrations of benzene, toluene, xylenes and ethylbenzene than retail packs from shops in residential areas.

The principle of this method is to fix first the piston height around 5 cm above the final bed height, pack against the piston (stall), and finally fix the final bed with the DAC. 

For example, the normal discharge rates for a power tool during a motor start-up or stall condition can appear to be the same as the short-circuit current conditions for a notebook computer even if both used a 4-series cell pack configuration. Therefore, the... 

The early analytical method applied to the quantitation of PCBs in oils uses a calibration technique developed by Webb and McCall in 1973. The method is based upon the detector response comparison obtained for a commercial PCB mixture with that of the sample and uses packed column gas chromatography with, typically, an electron capture detector (see ASTM method D-4059). Slight variations in the aroclor manufacturing process, or chemical alteration of the analyte PCB, causes problems with the quantitation. Reasonable results can be achieved, however, in the analysis of insulating oils where the PCB has not been degraded. More sophisticated analytical methods have been published by Albro et al. (1979), Lao et al. (1976), Sherma et al. (1975) and Stalling (1979).
