Abstract: A method of mass spectrometry is disclosed comprising digitizing a signal output from a detector to provide a first digitized signal. A finite impulse response (“FIR”) filter, a digital filter or an echo cancellation filter is applied to the first digitized signal in order to reduce the effect of baseline perturbations, echoes or ringing effects. Alternatively, an analog signal output from a detector is passed to one or more first power splitters or dividers, wherein one or more first transmission lines are attached to one or more ports of one more said first power splitters or dividers in order to reduce the effect of baseline perturbations, echoes or ringing effects.

Abstract: A cargo bar having reduced costs due in part to being constructed from square tubes and due to being collapsible to a length that fits a 4 foot pallet so as to facilitate shipping and storage. Pressure induced extension of the cargo bar against opposed truck walls is provided by a rack and pinion gear arrangement, the rack teeth provided on a first tube wall and the pinion teeth provided on a pivotal lever mounted to a second tube. The bar ends have pressure pads that will conform to side walls of a truck or van and the tube interior is alternately fitted with retractable track pins that extend through the pads and retract behind the pads to accommodate different cargo bar systems.
