PG Instruments new hydride generation system with integrated precision micro peristaltic pump, improves ICP detection limits for hydride-forming elements such as As, Se, and Sb. Sub-ppb levels of such elements are often difficult to detect with ICP, but the PG Instruments Hydride Generator converts hydride-forming elements to gas, increasing signal intensity. intensity. In a low-volume quartz gas-liquid separator the elemental hydrides are separated from liquid waste then carried to the ICP injector. The system can increase ICP sensitivity by an order of magnitude or more over a nebuliser-only system.
PG仪器采用集成精密微蠕动泵的氢化物发生系统，提高了As、Se、Sb等氢化物形成元素的ICP检测限。这些元素的亚ppb水平通常很难用ICP来检测，但是PG仪器氢化物发生器将氢化物形成元素转化为气体，从而增加了信号强度。在低体积石英气液分离器中，将元素氢化物从废液中分离出来，然后送入ICP注射器。该系统比纯星云系统的ICP灵敏度提高一个数量级或更多。
The hydride generator is available with 4 or 6 channels. The 4-channel version is for basic hydride formation, and the 6-channel version allows the user to add an internal standard, such as Bi.
氢化物发生器有4或6个通道可供选择。4通道版本用于碱性氢化物形成，6通道版本允许用户添加内部标准，如Bi。
