Introduction

Glen H Hughes is a notable inventor based in Midland, MI (US). He has made significant contributions to the field of chromatography and data analysis, holding 2 patents that showcase his innovative approaches.

Latest Patents

One of his latest patents is titled "Method for interpreting complex data and detecting abnormal instrumentor." This invention provides an improved method for determining when a set of multivariate data, such as a chromatogram or a spectrum, is an outlier. The method utilizes Principal Component Analysis to create a model that describes a calibration set of spectra or chromatograms known to be normal. It also includes the creation of residuals that describe the portion of a particular spectrum or chromatogram not explained by the model. A key improvement involves using an average residual spectrum calculated for the calibration set as a reference point for comparison. Additionally, the invention allows for the separation of complex data into various sub-parts, facilitating the detection of outliers in any sub-part.

Another significant patent is the "Apparatus and method for establishing a temperature gradient in capillary gas chromatography." This invention involves a chromatography column surrounded by an inner tube and an outer tube. A first heat transfer fluid is heated and flowed between the inner tube and the column, while a second heat transfer fluid, at a lower temperature, is flowed in the opposite direction. This method establishes a negative temperature gradient along the capillary gas chromatography column, optimizing the analysis of samples.
