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。 上海進口分析儀采購***電極爐頭設(shè)計,提高脈沖爐熱交換效率。
Procedure - Solid Samples
Prepare the instrument as outlined in the operator's instruction manual.
Determine the instrument blank.
Login a minimum of 3 Blank replicates.
Press the Analyze button on the instrument screen. After a short delay, the loading head slide-block will open. Place a 502-344 Nickel Basket into the loading head.
Note: samples using automation should be placed in the appropriate autoloader position before starting the
analysis sequence. Once the sequence has started, the automatic analysis will start and end automatically.
Sample Preparation
Typically, titanium and zirconium samples are chemically etched to remove surface contamination when oxygen and nitrogen are determined. However, etching can introduce hydrogen into the sample.
ASTM method E 1409 "Determination of Oxygen and Nitrogen in Titanium and Titanium Alloys by the Inert
Gas Fusion Technique", as updated in 1996, permits either etching or abrading (filing) of the test specimen.
ASTM E 1447 "Determination of Hydrogen in Titanium and Titanium Alloys by the Inert Gas Fusion Thermal
Conductivity/Infrared Detection Method" permits surface preparation by abrading (if necessary to remove
contamination). Differences in sample preparation present somewhat of a dilemma regarding simultaneous
determination of O, N, and H in titanium. However, abrading samples with a file to remove surface
contamination will yield accurate O, N, and H results. The ONH836 utilizes a high-power electrode furnace to quickly and efficiently release the target gases from within the sample, which allows for a very rapid simultaneous determination of oxygen, nitrogen, and hydrogen.
