    • A probe drive system (24) of a precision liquid handler (20) sequentially inserts probe tips (36) of a multiple probe array (30) into a locator well (76) at a known position on a locator bed (28). The position of each probe tip (36) is determined by driving the probe tip (36) into contact with points on the side wall (88) of the locator well (76) and sensing the contacts. The positions of the probe tips (36) are mapped and checked for skew of the probe array (30). The probe tip positions ae overlaid to determine probe tip scatter. If a probe tip (36) is excessively misaligned, it is inserted into the locator well (76) and driven against the side wall (88) to bend the probe and reduce the misalignment of the probe tip (36). The center of the probe tip scatter is determined and is used by the probe drive system (24) as a global correction factor. Probe tips (36) with known positions are inserted into spaced apart locator wells (78,80) to detect skew of the locator bed.
    • 精密液体处理器(20)的探针驱动系统(24)在定位器床(28)上的已知位置处依次将多个探针阵列(30)的探针尖端(36)插入到定位器井(76)中。 通过驱动探针尖端(36)与定位器孔(76)的侧壁(88)上的点接触并感测触点来确定每个探针尖端(36)的位置。 对探针尖端(36)的位置进行映射并检查探针阵列(30)的偏斜。 探针尖端位置ae重叠以确定探针尖端散射。 如果探针尖端(36)过度不对准,则将其插入定位器孔(76)并被驱动抵靠侧壁(88)以弯曲探针并减小探针尖端(36)的未对准。 探针尖端散射的中心被确定并被探针驱动系统(24)用作全局校正因子。 具有已知位置的探针尖端(36)插入到间隔开的定位孔(78,80)中以检测定位器床的偏斜。

    • A piston carrier (46) supports an elongated, slender piston rod (2) for reciprocation in a pump cylinder (30) to pump fluid into and out of the cylinder (30). The piston rod (12) is made of a material such as sapphire or zircon and has a diameter less than about ten millimeters, and the pump can provide flows of from about 50 nanoliters to about 250 microliters per minute at pressures of several hundred bars. A drive motor (18) rotates a threaded screw (58) and a drive nut (70) of a drive system (26) applies a linear drive force to the piston carrier (46). A ball and socket connection (74) between the drive system (26) and the piston carrier (46) avoids the need for precise alignment to prevent breakage of the fragile piston (12). A magnet (80) in the socket (78) holds the ball (76) in place and avoids the need for a spring or other mechanical holder. The socket (78) also includes a ring (88) of a low reluctance material surrounding the ball (76) to increase the magnetic retention force.
    • 活塞架(46)支撑用于在泵缸(30)中往复运动的细长活塞杆(2),以将流体泵入和泵出缸(30)。 活塞杆(12)由诸如蓝宝石或锆石的材料制成并且具有小于约十毫米的直径,并且泵可以在几百巴的压力下提供约50纳升至约250微升/分钟的流量。 驱动马达(18)旋转螺杆(58),并且驱动系统(26)的驱动螺母(70)将线性驱动力施加到活塞架(46)。 驱动系统(26)和活塞架(46)之间的球窝连接(74)避免了精确对准的需要,以防止易碎活塞(12)的损坏。 插座(78)中的磁体(80)将球(76)保持在适当位置并避免需要弹簧或其他机械支架。 插座(78)还包括围绕球(76)的低磁阻材料的环(88),以增加磁保持力。

    • A method for automated loading of liquid sample to a liquid chromatography testing device is provided including installing a disposable tip on a probe, moving the probe with an automated liquid handler to a loading position proximate to a sample, and drawing a sample into the disposable tip. The probe is then moved to an injection position proximate an injection port, and the sample is injected from the disposable tip into the injection port. Also provided are the novel injection ports. After injection of the sample, the disposable tip is then removed from the probe. These steps may be repeated a plurality of times to sequentially load a plurality of samples. An exemplary method of the invention is directed to use with a liquid chromatography apparatus. An apparatus for assisting in the removal of the disposable tip is also provided.
