  • Patent number: 7695686
    Abstract: Sample preparation device and method for desalting and concentrating samples prior to further analysis such as by MALDI TOF and/or electro-spray ionization (ESI) mass spectrometry. The device in accordance with an embodiment of the present invention contains a three dimensional structure preferably comprising a plurality of sorptive particles entrapped in a porous polymer matrix so as to form a device capable of carrying out solid phase extraction. The device is manufactured by introducing casting solution containing polymer and optionally particles into a housing, and subsequently exposing the device to a quench bath for a time sufficient to allow for solvent exchange and precipitation to form the composite structure in the housing. The present invention is also directed towards a method of sample preparation using the device of the present invention.

  • Publication number: 20060047369
    Abstract: A method and system for controlling distributed energy resources is provided. Notification of an upcoming regional power distribution event is received and a distributed energy resource affected by the upcoming event is determined or identified. A first notification message is sent to an affected distributed energy resource asset owner or other administrator to notify the distributed energy resource asset of the event. An event data process is initiated to monitor and collect data associated with the event and an event control process is initiated to control one or more affected distributed energy resource asset during the event. The event control process and the event data process are terminated at the end of the event.
