Procedure – Powder/Chip Samples

Prepare the instrument as outlined in the operator's instruction manual.

Login a minimum of three Blank reps.

Press the Analyze button on the instrument screen. After a short delay, the loading head slide-block will open. Insert a *** Nickel Capsule (leave capsule open) into the open port at top of 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.

氧氮氫分析儀的常見故障及解決方法：

氧和氮空白值超過20。這是由于氣流小，不能將爐子中的空氣驅趕出去?？烧{節(jié)氣體流量，調節(jié)載氣壓力在0.2~0.4MPa。接通儀器載氣，放一個石墨坩堝在下電極上，打開主電源開關，點擊軟件上的關爐按鈕，關閉爐子并等待10s。調節(jié)流量調節(jié)器，直到流量計a顯示為30L／h，打開爐子。調節(jié)調節(jié)器直到流量計b顯示為50L／h，再次關閉爐子。如果以上設置不穩(wěn)定，則增加流量至100L／h，反復調節(jié)直至儀器穩(wěn)定。 上海進口分析儀優(yōu)惠價格強力內循環(huán)水冷裝置。

Procedure – Powder/Chip Samples

Instrument calibration/drift correction.

Calibrate/drift following the procedure outlined in the operator's instruction manual.

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.
