The disclosure describes embodiments of an apparatus including a first gas chromatograph including a fluid inlet, a fluid outlet, and a first temperature control. A controller is coupled to the first temperature control and includes logic to apply a first temperature profile to the first temperature control to heat, cool, or both heat and cool the first gas chromatograph. Other embodiments are disclosed and claimed.

A can lid is provided to be made of a steel plate and easy to be opened. An opening piece is enclosed by a score line formed on a periphery of a panel portion. An installation portion of a tab is attached to the opening piece at a site close to a circumference of the opening piece. The tab includes a finger grip portion that is situated closer to a center of the opening piece than the installation portion, and a nose portion that is situated on an opposite side to the finger grip portion at a radially outer side of the score line. A portion of the panel portion underneath the nose portion serves as a support section that supports the nose portion from below. An outer circumferential bead is formed on a radially outer side of the score line to enhance a bending stiffness of the support section.

Non-crosslinked polyolefin films or doped crosslinked polyolefin films (i.e., crosslinked polyolefin films that include a tear-alignment additive) may be used to shrink-wrap packages to create a wrapped package that is protected from tampering and damage but is also easy to open with little effort required by the customer. There is no need for perforations, and the films are quiet when torn, folded, cut, etc. Tear initiating cuts may be formed in the film. A tab may be placed over the film, and when the tab is pulled it applies enough force to start a pair of straight tears. The tears may be parallel or perpendicular to each other. The tears propagate in non-crosslinked polyolefin easily in the machine direction of the film as the tab continues to be pulled. In a doped crosslinked polyolefin, the tears propagate in the machine direction or perpendicular to the machine direction of the film.

An apparatus is disclosed and includes a can, which has an end wall incorporating a vent panel and a pouring panel, both panels presenting a contour defined by a rupture line. The apparatus includes an actuation tab with an extracting end portion affixed to the vent panel. The actuation tab includes a punching end portion affixed to the pouring panel and a lower end tooth to be pressed against a spot region of the rupture line of the pouring panel. The actuation tab includes a grip portion affixed to the extracting end portion and is designed to be manually and upwardly actuated for detaching the vent panel from the end wall. The grip portion is designed to punch and rupture the spot region of the rupture line of the pouring panel and, subsequently, detaching the latter from the end wall.

A foil for closing an opening in a container, such as an easy opening container, includes foil to be adhered to the container. The foil includes a tab for releasing the foil from the container. The tab is folded on the foil and connected thereto via a connector and the tab is provided with a breakout device such that upon actuating the tab a visible and irreparable broken out part is formed and adhered to the foil.

A tamper evident metal foil closure for a container which provides visual evidence of tampering in the form of damage to the metal foil (e.g. tearing) and evidence of temperature tampering of the metal foil when heat is used to remove and reseal the metal foil. Containers sealed with this novel metal foil closure make it more difficult to tamper with or remove the container contents and then return the container for a refund.
