Richmond, Tang, Caputto, and Trucco, in Wolfs laboratory, using column chromatography, reported the successful separation of the two proteolytic enzymes from human gastric juice (R5, R6, T2-T6). Of these, one had optimum proteolytic activity at pH 2 (pepsin), while the other... 

While the first goal of most analysis is to obtain a chromatogram with adequate separation, much work remains to convert the chromatographic raw data into useful quantitative information, mostly as chromatography reports. In the past two decades, both HPLC instrumentation and chromatographic data systems have made tremendous improvements in performance and refinements. Chapter 4 gives a brief history of its evolutionary progress of data... 

Figure 5.8. Schematic illustrating the typical flow path from raw data to chromatography reports, listing the processes and methods used.

While the functional details of individual data systems vary greatly, Figure 5.8 shows the typical key processes or functions (integration, calibration, and quantitation) to convert sample chromatograms (raw data from the detector) into useful chromatography reports. These processes are controlled by a set of user-specified methods residing in the data system as summarized in Table 5.1.

Earlier studies had indicated aldehyde and ketone formation in the oxidation of ethylene however, later work using mass spectro-graphic analysis and gas chromatography reported no products other than CO2 and water. The coulombic efficiency determinations for the anodic oxidation of other unsaturated hydrocarbons in acid solution indicate that CO2 is the main reaction product (cf. Table 17). For lower olefins, i.e., C2H4 and oxidation is complete. For larger compounds, other products are formed however, the primary product is CO2. A general equation for hydrocarbon electro-oxidation can thus be written as...
