氧氮氫分析儀

氧氮氫分析儀是一種用于材料科學領(lǐng)域的儀器，于2016年03月09日啟用。

技術(shù)指標

測量范圍： ON 低氧0.0－300ppm OH 低氧0.0－300ppm 高氧0.0－2% 高氧0.0－2% 低氮0.0―300ppm 低氫0.0－50ppm 高氮0.0－2% 高氫0.0－1000ppm 靈敏度： 氧0.01ppm；氮0.1ppm；氫0.01ppm。

主要功能

該儀器配置有16位微處理器和兩個**的分別檢測高氧和低氧的 紅外檢測池。氮和氫通過雙重范圍的熱導檢測池測量。分析過程中可自動實現(xiàn)從 低范圍到高范圍的切換。樣品在高功率脈沖爐的石墨坩堝中加熱可達3000℃以上 高溫，脈沖爐采用循環(huán)水冷卻。該儀器具有靈敏度高、性能好、測量范圍寬和分 析結(jié)果準確可靠等優(yōu)點。ONH-2000氧氮氫分析儀是為快速、準確測定銅、鋼、鑄 鐵、合金、鈦、鎳、鉬、鋯、陶瓷和其它無機材料中氧、氮、氫的含量而專門設(shè)計 制造的。 浙江美國LECO氧氮氫分析儀優(yōu)惠價格強力內(nèi)循環(huán)水冷裝置。

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，被測后的氣體導入化學試劑管，這時二氧化碳和水被化學試劑除去，氮元素通過熱導檢測池含量被測定。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。

Oxygen, Nitrogen, and Hydrogen in Refractory Metals

Summary

Titanium is a metal that can be combined with elements such as aluminum, vanadium, molybdenum, and tin to produce high-strength, lowdensity, and corrosion-resistant alloys. Titanium alloys are used by the military, medical devices, sporting goods, and aerospace industries because of these properties, and due to the strict demands of these industries, effort needs to be taken to assure that the material meets the highest of quality standards.

Sample Preparation

Sampling and sample preparation of refractory metals such as titanium and zirconium is somewhat different from that of steel. Unlike steel samples, hydrogen is not as mobile in this group of materials; therefore, storage in liquid nitrogen or dry ice is not required. However, it is important to keep the sample cool when cutting or sectioning. Sample preparation for oxygen and nitrogen determination has beendifferent from that of hydrogen determination.
