氧氮氫分析儀是快速、準確分析氧、氮、氫元素的、高性能儀器，整機采用模塊化、一體化設(shè)計，即主機由可靠的脈沖電極爐、高靈敏高精度的檢測系統(tǒng)、布局合理和氣密性好的氣路系統(tǒng)、可靠耐用的電源系統(tǒng)、穩(wěn)定的電路系統(tǒng)、高校節(jié)能的水循環(huán)散熱系統(tǒng)等六個**的硬件模塊單元組成。

氧氮氫分析儀的測量原理：

測量范圍非常***。分析樣品時，樣品被稱重后放到樣品端口中，然后用載氣進行沖洗，防止大氣（含氧氣和氮氣）進入到爐子系統(tǒng)中。

石墨坩堝在脈沖爐中脫氣，以盡量減少自帶的污染。經(jīng)過穩(wěn)定階段后樣品落入坩堝中并熔融。樣品中的氧與石墨坩堝中的碳反應(yīng)生成一氧化碳。氮和氫以單質(zhì)的形式釋放。載氣和樣品氣體通過粉塵過濾網(wǎng)后再進入到氧化銅催化爐中，將一氧化碳氧化成二氧化碳。

二氧化碳進入到紅外池中用于測定氧含量，被測后的氣體導(dǎo)入化學(xué)試劑管，這時二氧化碳和水被化學(xué)試劑除去，氮元素通過熱導(dǎo)檢測池含量被測定。測量氫時，載氣換為氮氣，樣品氣體通過舒茨試劑而不是氧化銅催化劑。測氧和氮時也可采用更廉價的氬氣作為載氣。 Cornerstone氧氮氫分析軟件分成4個主要部分：分析、診斷、設(shè)定、儀器，界面可快速導(dǎo)航和組織。

Method Selection

Two methods are described in this application note; either method can be used to analyze iron, steel, nickel-, and cobalt-base alloys. The Precision Method is recommended for general use and will provide the best precision and accuracy throughout the typical O, N, and H concentrations found in this group of metals; approximate cycle time is 3.5 minutes. The Fast Track method can be used where speed of analysis is a critical component; for example, when molten metal is being sampled and results are required in the shortest possible time. This method will produce suitable results for most samples; approximate cycle time is 2.25 minutes. As noted above, sampling and sample preparation are key elements to accurate O, N, and Hdetermination as well. It is up to the user to determine which method best meets their needs.
