    摘要： The present invention pertains to an apparatus for gathering analyte. The apparatus comprises a pumping mechanism for pumping solvent at supercritical pressure. The apparatus also comprises an extraction mechanism which receives a first sample and at least a second sample separate and distinct from the first sample and extract analyte from them essentially simultaneously. The extraction mechanism is connected to the pump mechanism to receive solvent at supercritical pressure for extracting the analyte from the samples. The apparatus additionally comprises a collection mechanism for collecting analyte from the solvent after the analyte has been extracted from the samples. The collection mechanism receives the supercritical solvent having the analyte extracted from the samples from the extraction mechanism. The present invention pertains to a method for extracting analyte. The method comprises the steps of pumping solvent at a supercritical pressure. Then there is the step of extracting analyte from N samples essentially simultaneously with the solvent at a supercritical pressure, where N is greater than or equal to two and is an integer. The N samples are separate and distinct from each other. Then there is the step of collecting the analyte of the N samples from the solvent.

    摘要： The invention provides a system and a method for obtaining from the patient's body information pertaining to the blood pressure and heart rate of a patient for the purpose of enabling a physician to monitor and prescribe treatment intended to maintain a patient's blood pressure within a predetermined range, for encouraging the patient to follow the treatment and for collecting information relating to the patient's blood pressure and heart rate. Signals are generated that represent the level of blood pressure and pulse rate of a patient in a form suitable for telephonic communication. The signals are transmitted to a remote central digital processor for storage and analysis. Data resulting from the analysis is submitted to the patient or physician. An off hook and ring detect circuit is provided preventing actuation of the system when telephonic access is unavailable.

    摘要： A syringe interface or adapter includes a first retaining member that pivots about an axis generally perpendicular to and offset from the axis of an injector piston when the syringe interface is attached to the injector. The first retaining member pivots in a rearward direction to engage a portion of the syringe flange. The syringe interface further includes a second retaining member slideably positioned within a passage in the syringe interface to slide in a direction generally perpendicular to the axis of the piston when the syringe interface is attached to the injector to engage a portion of the syringe flange. The first retaining member and the second retaining member preferably cooperate to engage the syringe flange around the entire perimeter of the syringe flange. The first retaining member is preferably biased toward an open position. The syringe interface can also include a rear portion having an attachment mechanism to attach the syringe interface to the injector.

    摘要： A supercritical fluid extraction (SFE) system. The SFE system includes a mechanism for providing supercritical fluid for extracting analyte from a sample. The SFE system also includes an extraction vessel and a mechanism for moving the extraction vessel into fluidic communication with the SFE system so that supercritical fluid can flow through the extraction vessel and extract analyte from the sample. Preferably, the SFE system is additionally comprised of a mechanism for holding a plurality of extraction vessels and an extraction chamber assembly. In this design, the moving mechanism selectively moves an extraction vessel from the holding mechanism into the extraction chamber in fluidic communication with the SFE system. Preferably, the SFE system further includes a computer for controlling the functions of the SFE system. The computer, for instance, could automatically and sequentially control the supercritical fluid extractions of the samples within the holding mechanism. The SFE system preferably includes a mechanism for collecting analyte from the fluid with analyte. The collecting mechanism is in fluid communication with extraction chamber assembly and preferably includes a restrictor for controlling the flow of fluid with analyte to the collecting mechanism. The restrictor converts the fluid with analyte from a first supercritical pressure to a second pressure which is less than the first supercritical pressure.

    摘要： A pump for liquefied gases is provided having a low thermal conductivity liner provided in the inner bore of the pump cylinder. The low thermal conductivity liner prevents transmission to the pump cylinder of heat generated during the compression of the liquefied gas. The liner is preferably formed from a ceramic, such as zirconium, or from a plastic. In addition to the provision of the low thermal conductivity liner, techniques for reducing the dead volume of retained gases in the pump chamber are utilized to prevent the transmission of retained heat from the these gases to the incoming charge of liquefied gases.
