Abstract:
Embodiments of a front-end pre-concentrator module, a back-end pre-concentrator module and a gas analysis subsystem are disclosed, as well as gas analysis systems using combinations of the front-end pre-concentrator module, the back-end pre-concentrator module and the gas analysis subsystem. Embodiments of disposable and re-usable moisture removal filters are disclosed for use alone or in combination with a gas analysis system.
Abstract:
This invention discloses a method for determining dissolved hydrocarbons in an amine solvent or sulfinol solution qualitatively and quantitatively. The analysis of dissolved hydrocarbons is done by diluting the sample with water and injecting it into the Gas Chromatograph via an auto injector. The sample components are separated by a polar column with oven temperature programming and detected by flame ionization detector (FID). The compositions of dissolved hydrocarbons are computed by gas chromatography or GC Chemstation based on the External Standard Method (ESTD).
Abstract:
Sample processing units useful for mixing and purifying materials, such as fluidic materials are provided. A sample processing unit typically includes a container configured to contain a sample comprising magnetically responsive particles, and one or more magnets that are in substantially fixed positions relative to the container. A sample processing unit also generally includes a conveyance mechanism configured to convey the container to and from a position that is within magnetic communication with the magnet, e.g. , such that magnetically responsive particles with captured analytes can be retained within the container when other materials are added to and/or removed from the container. Further, a sample processing unit also typically includes a rotational mechanism that is configured to rotate the container, e.g. , to effect mixing of sample materials disposed within the container. Related carrier mechanisms, sample processing stations, systems, and methods are also provided.
Abstract:
An apparatus according to the present invention includes a plurality of sample spraying devices, each of which connects to an LC column. The apparatus includes an electrical circuit that can turn a high voltage between 1 and 5 KV on and off on the time-scale of nanoseconds to milliseconds. The circuit is controlled by a computer program which applies the high voltage to each spray device in a Hadamard sequence. The spray devices are positioned aiming at the mass spectrometer inlet. The preferred configuration of arrangements for the spray devices are in a circle or an arc of a circle around the inlet of a mass spectrometer.
Abstract:
A pin valve assembly and a method of controlling the flow of fluids comprising a pin block housing pin valves, a fluid plate with a fluid channel for fluidically communicating with the pin valves, and a fitting block housing fittings for fluidic communication with the fluid plate and for fluidic communication with fluidic components. The fluid flow through the channels of the fluid plate are controlled by the fluidic components and the pin valves.

Proceso analítico de separación de especies volátiles de aplicación a muestras líquidas, sólidas o mezcla de ambas, caracterizado por la hibridación de los procesos implicados en las técnicas de espacio de cabeza dinámico y perevaporación analítica, así como el diseño de un módulo básico para llevar a cabo dicha separación analítica.
Abstract:
The present invention relates to multi-phase protein separation methods capable of resolving and characterizing large numbers of cellular proteins, including methods for efficiently facilitating the transfer of protein samples between separation phases. In particular, the present invention provides an automated system for the separation, identification, and characterization of protein samples. The present invention thus provides improved emthods for the analysis of samples containing large numbers of proteins.
