International Classification:

G01N 1/00
G01F 23/00

US Classification:

73 6456, 25044011

Abstract:

Systems and methods for supporting a liquid against a vacuum pressure in a chamber can enable analysis of the liquid surface using vacuum-based chemical analysis instruments. No electrical or fluid connections are required to pass through the chamber walls. The systems can include a reservoir, a pump, and a liquid flow path. The reservoir contains a liquid-phase sample. The pump drives flow of the sample from the reservoir, through the liquid flow path, and back to the reservoir. The flow of the sample is not substantially driven by a differential between pressures inside and outside of the liquid flow path. An aperture in the liquid flow path exposes a stable portion of the liquid-phase sample to the vacuum pressure within the chamber. The radius, or size, of the aperture is less than or equal to a critical value required to support a meniscus of the liquid-phase sample by surface tension.

US Classification:

210656, 2101982, 210287, 502416, 502401

Abstract:

Embodiments disclosed herein include functionalized graphitic stationary phase materials and methods for making and using these materials, including the use of these materials in separation technologies such as, but not limited to, chromatography and solid phase extraction. In an embodiment, a functionalized graphitic stationary phase material may be manufactured from high surface area porous graphitic carbon and a radical forming functionalizing agent. The radical forming functionalizing agent produces an intermediate that forms a covalent bond with the surface of the porous graphitic material and imparts desired properties to the surface of the graphitic carbon.

Abstract:

A method for forming a fluorinated oxostannate film involves vaporizing a volatile fluorinated alkyltin compound having at least two hydrolytically sensitive functional groups or at least two reactive functional groups which are sensitive to oxidation at a temperature greater than 200 C.; providing a substrate; physisorbing or chemisorbing the fluorinated alkyltin compound onto the substrate; and exposing the physisorbed or chemisorbed fluorinated alkyltin compound to a sequence of hydrolysis, irradiation, and/or oxidation steps to form the fluorinated oxostannate thin film on the substrate. Fluorinated alkyltin compounds having formula (I) are also described, in which Ris a fluorinated or partially fluorinated linear or branched alkyl group having about 1 to about 5 carbon atoms, X is a dialkylamino group having about 1 to about 4 carbon atoms, and n is 1 or 2:
