Improved suppressor device

The invention provides an improved suppressor device. An apparatus for detecting analytes in a liquid sample may include an elongated primary channel through which an ionic species flows, the primarychannel extending through a primary channel member, a first regenerant channel through which a regenerant flows, the first regenerant channel extending adjacent to the primary channel and being formedin a first block, a first charged barrier having exchangeable ions capable of passing ions of only one charge, positive or negative, and of blocking bulk liquid flow, the first charged barrier disposed between the primary channel member and the first block for separating the primary channel from the first regenerant channel, and a first sealing member disposed between the first charged barrier and the first block defining the first regenerant channel. 改良的抑制器装置。一种用于检测液体样品中的分析物的设备可以包括一种离子性物质流经的一个长条形主通道，该主通道延伸穿过一个主通道构件；一种再生物流经的一个第一再生物通道，该第一再生物通道靠近该主通道延伸并且被形成在一个第一区块中；一个具有可交换离子的第一带电屏障，该第一带电屏障能够通过仅具有一个正或负电荷的离子并且能够阻断本体液体流，该第
