Latest Patents

Among his latest patents, DeFord has developed a "Method and apparatus suitable for repeated, accurate chemical analyses." This invention allows for a continually repeated chemical analysis of a process stream sample by interposing the sample in a flow of titrant. The flow is interrupted only to permit the interposition of the sample, which is then held in a chromatographic column for titration. The reaction product eluted from the column is subsequently detected.

Another significant patent is for "Quantitative chromatographic analysis without calibration." This method enables the quantitative analysis of the concentration of individual components in a sample using a chromatographic analyzer without the need for calibration. By utilizing two chromatographic analyzer systems to analyze identical samples with different carrier fluids, the difference in response is proportional to the properties of the carrier fluids and the concentration of the desired component. This innovative approach eliminates the need for calibration of the chromatographic analyzer detectors.
