Introduction
Michael J Leveille is a notable inventor based in Northbridge, MA (US), recognized for his contributions to the field of optical calibration technologies. With a total of five patents to his name, Leveille has made significant advancements in the calibration of UV absorbance detectors, which are essential in various scientific and industrial applications.
Latest Patents
Leveille's latest patents include a calibration medium for wavelength calibration of UV absorbance detectors and methods for calibration. This invention features an optical medium designed for calibrating UV absorbance detectors, along with methods for creating such a medium. The optical calibration medium consists of a gel-sol silica glass monolith that incorporates a rare-earth dopant. This dopant exhibits at least one spectral feature in the far UV range, allowing for precise calibration. The constituents of the gel-sol silica glass are selected to ensure that the rare-earth doped sol-gel glass monolith has a transmittance of at least about 50% at approximately 250 nm. The rare-earth materials chosen for use as dopants display a wide range of spectral features, particularly between 190 nm and 700 nm, with distinct features in the far UV range.
Another significant patent is the approach to short measurement path-length flow cells. This innovation involves a photometric measurement flow cell with adjustable measurement path-lengths that can be reduced to less than 0.1 mm. The path-length is controlled by a common flow cell body and the dimensions of a stepped sealing optical element. By replacing one stepped element with another of a different length, the flow cell's measurement path-length can be reliably adjusted.
