Title: Innovations of Hansueli Buser
Introduction
Hansueli Buser is a notable inventor based in Arlesheim, Switzerland. He has made significant contributions to the field of gas chromatography, holding a total of 3 patents. His work focuses on improving sample introduction systems and charging mechanisms for gas chromatographs.
Latest Patents
One of his latest patents is a sample charger for a gas chromatograph. This innovative device features a charging chamber designed for connection to the separating column of the gas chromatograph. It allows for the insertion of a sample container in the form of a tube, utilizing a rod-shaped sample holder. The design includes carrier-gas inlet openings, enabling the interior of the insertion tube and sample container to be scavenged with inert gas during the insertion process. Once the sample container is fully inserted, the carrier gas flows through the container into the separating column.
Another significant patent is a sample introduction system for a gas chromatograph. This system includes a chamber with a needle that pierces a sample held in a holder. The needle is designed with a conical point, which opens into a passageway that communicates directly with the separating column. As the sample is pushed onto the needle, it seals against the conical surface, allowing for the ingress of carrier gas supplied to the chamber.
