Abstract: A liquid handling system 10 for use with a liquid sample in a container 60 includes a probe 100 and an actuator 37. The probe 100 is configured to be inserted into the container 60 to contact the liquid sample in the container 60. The probe has a probe axis. The probe includes an elongate probe body 110 having a distal end, and an integral mixing device 140 on the probe body proximate the distal end. The actuator 37 is operable to reciprocate the probe in the container along the probe axis such that the mixing device generates mixing currents in the liquid sample.

Abstract: Certain embodiments described herein are directed to reflectron assemblies and methods of producing them. In some configurations, a reflectron comprising a plurality of lenses each comprising a planar body and comprising a plurality of separate and individual conductors spanning a central aperture from a first side to a second side of a first surface of the planar body is described. In some instances, the plurality of conductors are each substantially parallel to each other and are positioned in the same plane.

Abstract: Certain embodiments described herein are directed to time of flight tubes comprising a cylindrical tube comprising an inner surface and an outer surface, the cylindrical tube comprising an effective thickness and sized and arranged to couple to and support a reflectron assembly inside the cylindrical tube. In some configurations, the cylindrical tube further comprises a conductive material disposed on the inner surface of the cylindrical tube, the conductive material present in an effective amount to provide a field free region for ions when the conductive material is charged.
