火焰原子化器

采用单缝石英管技术作为火焰原子化器的原子捕集阱，以火焰法测定地表水中Cu、Pb、Zn、Cd等痕量元素，进一步提高了石英管法的灵敏度。

Taking single-edge slotted quartz tube as flame atomic-trap , using flame atomic-absorption spectrometry to determine trace Cu , Pb , Zn and Cd elements in surface water , so that the sensitivity of the quartz tube will be increased .

还叙述了新设计的氢空气扩散焰火焰原子化器。

A new , design of atomization furnace with flame diffusing air to hydrogen is described .

火焰原子化器的设计改进

An Improved Flame Atomizing Device

采用硼氢化钠还原法将试样中硒还原为挥发性硒化氢，氩为载气将硒化氢吹出并导入火焰原子化器进行原子荧光测定。

The method is based on the reduction of Selenium to volatile SeH 2 which is bubbled out by a carrier gas of pure argon and then swept to an Ar H 2 flame quartz atomizer to measure its atomic fluorescence .
