Abstract: The present invention relates to an apparatus and method for sampling, retrieving and storing fluid samples obtained from a liquid environment. An embodiment comprises a sample holding unit, at least one check valve, a trigger valve coupled to a triggering mechanism, and a decanting valve. Alternatively, apparatus comprises a holding unit, a four-way connector, at least one pressure relief device, a first flow regulating valve, a second flow regulating valve, and a ball valve. A method for sampling, retrieving and storing fluid samples obtained from a liquid environment includes deploying a sample apparatus to the site of interest in a liquid environment, opening the trigger valve with the triggering mechanism, allowing fluid to enter the sample holding unit until the internal pressure becomes substantially equivalent to the external pressure, once check valve closes, the triggering mechanism closes the trigger valve and the sample apparatus is retrieved from the liquid environment.

Abstract: Methods for separating glass articles from glass substrate sheets are described herein. In one embodiment, a method includes focusing a laser beam on at least one surface of the glass substrate sheet such that the laser beam has an asymmetrical intensity distribution at the at least one surface of the glass substrate sheet. The method further includes translating the laser beam on the at least one surface of the glass substrate sheet along a desired groove line to form at least one groove on the at least one surface of the glass substrate sheet. The at least one groove extends partially through a thickness of the glass substrate sheet along the desired groove line and has bevelled or chamfered walls. The glass article may be separated from the glass substrate sheet along the at least one groove.
