    Abstract: A device and a method for determining a status of a thermal chamber in a liquid chromatography system. The method (200) includes a step (210) of monitoring the temperature of a heat sink, a thermal chamber and/or an ambient temperature outside the thermal chamber. A step (212) sends these temperature measurements made by the sensors (110,111,112) to a computer system (120). The method (200) includes another step (220) of monitoring the power use of a heater/cooler engine, and sending (222) power information to the computer system (120). The method steps (210) and (212) may be occurring simultaneous to the method steps (220), (222) in one embodiment. The method (200) further includes a step (230) of receiving the temperature measurements and the power information generated or taken by the sensors from the steps (210), (212), (220), and (222), by the computer system. A next step (232) analyzes the temperature measurements, information, data or the like that is received and determines (234) a status, such as whether ice has formed on a heat sink of the system.

    Abstract: A liquid chromatography sample manager includes a sampling mechanism; a sample platter mounted in the sampling mechanism, the sample platter configured to rotate about a first vertical axis; a needle arm mounted within the sampling mechanism, the needle arm configured to rotate about a second vertical axis; and a sample delivery system in fluidic communication with solvent delivery system, the sample delivery system including a sample needle attached to the needle arm, the sample delivery system configured to transfer a first sample from a first sample vial carrier located in the sample platter into a chromatographic flow stream.
