Abstract: Computer-implemented methods and computer-readable media are disclosed for providing a spectroscopic film selection tool to select one or more of a plurality of films for use in a spectroscopic analysis. At a first computing system, a spectroscopic film selection tool is stored in a non-transitory storage medium. The spectroscopic film selection tool includes a set of machine-readable instructions configured to execute on a second computing system. The machine-readable instructions are configured to elicit user input regarding attributes of a spectroscopic analysis and, based on the user input, identify one or more of a plurality of films for use in a spectroscopic analysis based on film data for each of the plurality of films.

Abstract: A sample analysis cup assembly, system and method for purging including a cell body, including a top end; a bottom end; a cell body wall extending axially from the top end to the bottom end; a transverse wall adjacent the top end, including a plurality of apertures extending therethrough; and a raised portion on the transverse wall including a central aperture extending therethrough; a rotatable cap, including a top surface; a bottom surface; and a series of apertures extending from the top surface through the bottom surface, the rotatable cap being structured to engage with the top end of the cell body; and a ring member structured to couple with the bottom end of the cell body are provided.

Abstract: A sample analysis cup, sample cup assembly, and method is provided including a cell body with an open top end including an outer top wall and an inner top wall, each extending axially and positioned in concentric relationship; a bottom wall extending from the outer top wall to the inner top wall, the bottom wall and the inner and outer top walls defining an internal reservoir therebetween; a transverse wall extending a selected distance from the inner top wall, the transverse wall partially closing the open top end; an open bottom end including an outer bottom wall and an inner bottom wall, each extending axially and positioned in concentric relationship, the outer and inner bottom walls defining an internal channel therebetween; and a hollow chamber defined between the open top end and the open bottom end.

Abstract: A portable sample pulverizing and/or pelletizing system and method operable in conjunction with a repetitive impact device includes a base member with an upper surface, a hollow sample chamber with an open top end, an open bottom end disposed on the upper surface of the base member, and an internal annular cutaway portion adjacent the open top end; and a plunger member, which repetitively impacts a sample material disposed in the hollow sample chamber, the plunger member being configured at one end to matingly engage with a repetitive impact device.

Abstract: A briquette press apparatus for compacting powdered materials having a programmable control monitoring the forces of the press. During compression, the programmable control measures the compression force being asserted against the powdered material and regulates the press so that the compression force equals a programmed reference value. During decompression, the programmable control monitors the pressure release rate of the press and regulates the press so that the measured pressure release rate matches a programmed reference rate.

Abstract: A sample cup for use in spectroscopy consists of a cap member having an extending peripheral flange about a closed top surface, with a downwardly extending cylindrical bottom section, the peripheral flange of the cap member has a through aperture located on the inner edge of the flange and extending towards the periphery, a cell body is of a tubular configuration with an opened top and bottom with the opened top surrounded by a flange having an aperture on an inner surface for communicating with the internal hollow of the cell body. The cap member is adapted to coact with the opened top of the cell body and is rotatably supported thereon, whereby in a first mode the through aperture communicates with the cell aperture to create a vent passageway and in a second rotatable position, the apertures do not align to create a closed cell mode.

Abstract: There is disclosed a sample cup for use in holding a sample for spectrochemical analysis. The sample cup consists of a cell member which is cup shaped and has a closed bottom and an opened top. The top surface of the closed bottom has a recessed section which extends towards the bottom surface at a given taper with the diameter being larger near the bottom surface of the closed bottom. This forms an area on the closed bottom which is relatively thin.Located on the bottom surface of the closed bottom is an upstanding plunger which is positioned within the thin area. The plunger has grooves directed from top to bottom on the side walls and when depressed ruptures the closed bottom of the cell to create a vent necessary to equalize pressure. The sample cup is adapted to have its top opening covered by a thin plastic film which is secured in position by a collar and snap on ring assembly.

Abstract: A sample vial for use in comminuting and blending material samples for spectrochemical analysis has a vial body section of a cylindrical configuration with a closed recessed bottom end having an inner concave semi-spherical surface. The body section has an opened top end with an inner flange surrounding the same. A cover member is also of a cylindrical configuration and has a closed recessed top end with the inner surface of the cover member of a concave semi-spherical shape. The cover member has an inner peripheral flange for insertion into an opened top end of the vial body section to form a friction fit closure which acts as a seal to prevent particle material from leaking out of the vial. The composite internal hollow of the vial provides a smooth uniform surface to allow a pestle to traverse the same when the vial is vibrated.
