International Classification:

G01N 1/10

US Classification:

422501

Abstract:

Described is a compound sample needle for a liquid chromatography system. In one embodiment, the compound sample needle includes a rigid needle having a coupling end with a face and a counterbore. The compound sample needle also includes a flexible tubing having an outer surface and a coupling end disposed in the counterbore of the rigid needle. The coupling end of the flexible tubing has a face adjacent to a base of the counterbore. The coupling ends of the rigid needle and flexible tubing are secured to each other by a weld formed along a circumference of the outer surface and the face of the rigid needle. A rigid sleeve protects the welded joint. The compound sample needle is suitable for injection into the high pressure mobile phase of ultra performance liquid chromatography systems.

Abstract:

A method and system for receiving CIMT encoded data transmitted in simplex mode. The receiver (12) is adapted to receive a stream of digital data and analyze successive portions thereof to identify a predetermined pattern of data. The receiver (12) outputs the received digital data in response to a detection of the predetermined pattern of data and, in the alternative, outputs other data in response to a failure to detect the predetermined pattern of data. In the illustrative embodiment, the stream of digital data is transmitted as conditional invert master transition encoded simplex data. The receiver (12) includes a CIMT decoder (16) which analyzes the input data to identify a master transition therein. The receiver (12) uses a local clock to analyze successive portions of the received data stream and word alignment logic to identify a master transition therein. In the best mode, the inventive teachings are implemented in a communications system having a CIMT encoder (13) which transmits a time scrambled flag bit along with a stream of CIMT encoded data.

G01N 30/54

Abstract:

To heat a flowing liquid, an apparatus includes a heater block assembly having a heater block made of thermally conductive material. The heater block assembly has a tube inlet, a tube outlet, and a tube path between the tube inlet and tube outlet. Tubing extends through the tube path from the tube inlet to the tube outlet. The tubing is in thermal communication with the heater block. A heater cartridge, in thermal communication with the heater block, is configured to provide heat to the heater block for transfer to liquid flowing through the tubing between the tube inlet and the tube outlet of the heater block assembly. Circuitry is in electrical communication with the heater cartridge to control a temperature of the heater block by controlling operation of the heater cartridge.
