Latest Patents

One of his latest patents is the "Multipass optical spectroscopy cell having a single transmission path." This invention describes optical cells designed for spectroscopy applications. The cells feature a series of discrete planar reflectors that are aligned and spaced apart at each end of the sample cavity. These reflectors can be surrounded by transparent windows, allowing divergent energy to be removed from the cell cavity. The design ensures a unique beam path for the energy beam, eliminating overlapping optical paths through the cell. This innovation provides well-defined detection signals with a very high signal-to-noise ratio.

Another significant patent is the "Device for residue handling minimization with vacuum-assisted separations." This device is designed for the efficient collection of residue from separation columns. It includes a manifold with multiple sample ports that are fluidly connected to a vacuum port through at least one channel. The residue is pulled through the sample ports into the channel and then directed to the vacuum port. From there, the residue can be moved directly to a drain or to a collection vessel connected with a drain, enhancing the efficiency of the separation process.
