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儀器采用集成精密微蠕動(dòng)泵的氫化物發(fā)生系統(tǒng)，提高了As、Se、Sb等氫化物形成元素的ICP檢測(cè)限。這些元素的亞ppb水平通常很難用ICP來(lái)檢測(cè)，但是PG儀器氫化物發(fā)生器將氫化物形成元素轉(zhuǎn)化為氣體，從而增加了信號(hào)強(qiáng)度。在低體積石英氣液分離器中，將元素氫化物從廢液中分離出來(lái)，然后送入ICP注射器。該系統(tǒng)比純星云系統(tǒng)的ICP靈敏度提高一個(gè)數(shù)量級(jí)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.

氫化物發(fā)生器有4或6個(gè)通道可供選擇。4通道版本用于堿性氫化物形成，6通道版本允許用戶添加內(nèi)部標(biāo)準(zhǔn)，如Bi。
