新疆专业分析仪供应商Cornerstone氧氮氧分析软件允许用户在单一分析界面中完成日常的所有工作,快速而且简单易用。
氧氮氢分析仪是快速、准确分析氧、氮、氢元素的、高性能仪器,整机采用模块化、一体化设计,即主机由可靠的脉冲电极炉、高灵敏高精度的检测系统、布局合理和气密性好的气路系统、可靠耐用的电源系统、稳定的电路系统、高校节能的水循环散热系统等六个**的硬件模块单元组成。
氧氮氢分析仪的测量原理:
测量范围非常***。分析样品时,样品被称重后放到样品端口中,然后用载气进行冲洗,防止大气(含氧气和氮气)进入到炉子系统中。
石墨坩埚在脉冲炉中脱气,以尽量减少自带的污染。经过稳定阶段后样品落入坩埚中并熔融。样品中的氧与石墨坩埚中的碳反应生成一氧化碳。氮和氢以单质的形式释放。载气和样品气体通过粉尘过滤网后再进入到氧化铜催化炉中,将一氧化碳氧化成二氧化碳。
二氧化碳进入到红外池中用于测定氧含量,被测后的气体导入化学试剂管,这时二氧化碳和水被化学试剂除去,氮元素通过热导检测池含量被测定。测量氢时,载气换为氮气,样品气体通过舒茨试剂而不是氧化铜催化剂。测氧和氮时也可采用更廉价的氩气作为载气。
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.
采用三个**的红外器检测氧含量,同时检测CO和CO2,然后在转化为CO2集中检测。Procedure - Solid Samples:
--Instrument calibration/drift correction.
Place the nickel basket containing the calibration/drift standard into the open port at the top of the loading head.
Press the Analyze button on the instrument screen again, the loading head slide-block will close and the lower electrode will open.
Clean the upper and lower electrode manually, or, if applicable, remove the crucible and press the analyze button to clean with the automatic cleaner.
