氧氮氫分析儀是快速、準(zhǔn)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(jìn)行沖洗，防止大氣（含氧氣和氮氣）進(jìn)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(jìn)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(jìn)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。上海禹重實業(yè)有限公司是一家專業(yè)提供分析儀的公司，歡迎您的來電哦！
