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.

氧氮氢分析仪的常见故障及解决方法：

氧和氮空白值超过20。这是由于气流小，不能将炉子中的空气驱赶出去。可调节气体流量，调节载气压力在0.2~0.4MPa。接通仪器载气，放一个石墨坩埚在下电极上，打开主电源开关，点击软件上的关炉按钮，关闭炉子并等待10s。调节流量调节器，直到流量计a显示为30L／h，打开炉子。调节调节器直到流量计b显示为50L／h，再次关闭炉子。如果以上设置不稳定，则增加流量至100L／h，反复调节直至仪器稳定。 江苏LECO分析仪多少钱
