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.
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。 元素分析仪咨询报价强力内循环水冷装置。
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.
