This approach is quite useful where clean fractions are desired and used for further experimental work. When recycle is used, it is normal practice to increase detector sensitivity and decrease chart speed during appropriate cycles in order to accommodate for the effects of band broadening and to obtain a better visual judgment of the resulting chromatogram.

Since the peak width on the baseline may be affected by adsorption and tailing effects, the peak s half width is used in the area calculation. This procedure for peak area calculation should only be applied to symmetrical signals. The area thus calculated is proportional to the concentration but slightly smaller than the true value. For an accurate determination of the half widths, a high chart speed must be chosen.

Effect of Detector Attenuation Change and Chart Speed on Peak Height,... 

A Perkin-Elmer Vapor Fractometer, Model 154, was used to separate the lead alkyls. The column used to effect the separation was a short 1-foot by J-inch column packed with 40% Nujol on 35-80 mesh Chromosorb. The helium flow rate was 100 cc per minute and a chart speed of g-inch per minute was used. The short column and a low temperature (70°C) were used to minimize possible decomposition of the organolead compounds. 

Use the method described above for the reduction by hydrazine, replacing hydrazine solution by 20.0 cm of H2O2 solution, prepared by 4-fold dilution of 20-volume H2O2. Check the chart speed compatible with die faster gas evolution in this case. Repeat using different samples and choose one sample of battery-active dioxide and prepared doped powders and study the effect of doping on the kinetics. 

Figure 4. Effect of the extract (BTJ, 42 mg i.v.) on tibialis anterior muscle (TIB), electrocardiogram (EKG), and arterial blood pressure (BP) in a 325 g anesthetized rat. The records were made at different chart speeds, as indicated by the time base. The inset just below the EKG trace shows details of the onset of the arrhythmia during the early stages of extract infusion.

Both the heat and mass transfer coefficients are functions of air velocity. However, at air speeds greater than about 15 ft/s (4.5 m/s), the ratio h kgis approximately constant. The wet-bulb depression is directly proportional to the difference between the humidity at the surface and the humidity in the bulk of the air. In the wet- and dry-bulb hygrometer, the wet-bulb depression is measured by two thermometers, one of which is fitted with a fabric sleeve wetted with water. These thermometers are mounted side by side and shielded from radiation, an effect neglected in the derivation above. Air is drawn over the thermometers by means of a small fan. The derivation of the humidity from the wet-bulb depression and a psychrometric chart are discussed later. 

The Pareto chart for gloss is shown in Figure 5. The largest effect was mold temperature. Barrel temperature was next followed by injection speed, pack pressure and screw speed (SCREWS).
