Abstract: An ion mobility spectrometer analytical instrument, including an ion mobility spectrometer, a swab interface, and a desorber assembly. The desorber assembly includes a heat transfer device configured to heat a desorber, as well as a supply configured to direct gas through the desorber. The instrument further includes a drift tube, high voltage device arrayed, at least in part, proximate to the drift tube, wherein the high voltage device is configured to change a polarity of a voltage applied to the drift tube and have an absolute voltage of about 500 to 1500 volts. The instrument further includes a reactant supply unit adapted to supply reactant during a sample substance analysis, and a control unit.

Abstract: A method for making a blade putter having a high inertia of rotation. The product of the method has a base, a ball-striking part, a toe weight and a heel weight. The base is made of a first material of relatively low mass, such as aluminum, and the other parts are made of a second material having a relatively high mass, such as copper or brass. A dovetailed groove is formed in the toe end of the base to slidingly receive a dovetailed protuberance formed in the toe weight and a dovetailed groove is formed in the heel end of the base to slidingly receive a dovetailed protuberance formed in the heel weight. A recess formed in a leading wall of the base receives the ball-striking part. Fasteners hold the parts together as they are machined so that respective perimeters of the weights are flush with the base. The fasteners are then removed and the base is anodized separately from the other parts.
