In certain embodiments, the gas-deflector plate is configured to be positioned between higher and lower pressure regions in a pressurized system, wherein the gas-deflector plate has a channel therethrough shaped and/or angled such that jetting gas moving through the channel enters the lower pressure region at an angle offset from the vertical axis of the gas-deflector plate and/or the channel. In other embodiments, a jet-deflector component is employed such that the jetting gas strikes such jet-deflector component and is re-directed in another direction. ## Claims ### Claim 1 A system comprising: a pressurized subsystem including a higher pressure region and a lower pressure region; a gas-deflector plate with a first surface facing the higher pressure region, a second surface facing the lower pressure region, and a channel extending through the gas-deflector plate, wherein the channel includes with a first opening in the first surface and an asymmetric opening in the second surface; and a jet-deflector component coupled to the gas-deflector plate. ### Claim 2 (depends on 1) The system of claim 1, wherein the gas-deflector plate has a longitudinal axis and a lateral axis that extends through the gas-deflector plate and are parallel to the first surface and the second surface; and wherein the gas-deflector plate has a vertical axis that is perpendicular to the longitudinal axis and the lateral axis; and wherein gas moving through the channel from the higher pressure region to the lower pressure region enters the lower pressure region at an angle offset from the vertical axis. ### Claim 3 (depends on 2) The system of claim 2, wherein the angle offset is at least 15 degrees. ### Claim 4 (depends on 2) The system of claim 2, wherein the asymmetric opening is formed from a first portion and a second portion of the channel, wherein the first portion is across the asymmetric opening from the second portion, and wherein the second portion has a greater angular offset from the vertical axis than the first portion. ### Claim 5 (depends on 1) The system of claim 1, wherein the pressurized subsystem comprises a differential pumping system. ### Claim 6 (depends on 1) The system of claim 1, further including an ion source, an ion accelerator, a differential pumping system, and a target chamber. ### Claim 7 (depends on 6) The system of claim 6, wherein said gas-deflector plate is positioned between the target chamber and the differential pumping system. ### Claim 8 (depends on 7) The system of claim 7, wherein the target chamber comprises the higher pressure region and said differential pumping system comprises the lower pressure region. ### Claim 9 (depends on 1) The system of claim 1, further including a mass spectrometer. ### Claim 10 (depends on 9) The system of claim 9, wherein said mass spectrometer includes a sample chamber, a differential pressure stage, and an ionization chamber. ### Claim 11 (depends on 10) The system of claim 10, wherein the gas-deflector plate is positioned between the sample chamber and the differential pumping stage. ### Claim 12 (depends on 11) The system of claim 11, wherein the sample chamber comprises the higher pressure region and the differential pressure stage comprises the lower pressure region. ### Claim 13 (depends on 1) The system of claim 1, wherein the first opening has a diameter of about 6-18 mm. ### Claim 14 (depends on 1) The system of claim 1, wherein the gas-deflector plate has a thickness between first surface and the second surface of about 13-40 mm. ### Claim 15 (depends on 1) The system of claim 1, wherein the gas-deflector plate has a circular or generally circular shape. ### Claim 16 (depends on 1) The system of claim 1, wherein most or all of the gas-deflector plate is composed of a metal. ### Claim 17 (depends on 16) The system of claim 16, wherein the metal is selected from the group consisting of: copper, tungsten, and stainless steel. ### Claim 18 (depends on 1) The system of claim 1, wherein the gas-deflector plate comprises one or more openings that allow attachment to the higher pressure region and/or the lower pressure region. ### Claim 19 (depends on 1) The system of claim 1, wherein the jet-deflector component is positioned in the lower pressure region. ### Claim 20 (depends on 19) The system of claim 19, wherein the jet-deflector component includes a surface; and wherein the gas entering the lower pressure region strikes the surface of the jet-deflector component and is re-directed in a different direction.
