氧氮氫分析儀的常見故障及解決方法

供電正常、通訊正常，點擊確認鍵后分析儀不工作。這是沒有水流，爐子溫度太高或儀器通道電壓不正常。如沒有水流，爐子溫度太高這些信息會顯示在顯示器畫面上，但沒有信息顯示說明這兩項正常。接下來檢查儀器通道零位電壓，如果比±3V高出1V以上，可能是因為氣瓶空了，或者是空氣進入到分析儀中。檢查并更換化學(xué)試劑，如果有空氣進入熱導(dǎo)池里，熱導(dǎo)池的電壓就會＜-6V，此時打開右面的門，堵住爐子氣體進口，10s后，熱導(dǎo)池電壓值必然升高。經(jīng)過逐一排查，**終確認堿石棉有問題，更換后儀器正常。 Cornerstone氧氮氫分析軟件同時支持***的數(shù)據(jù)文檔格式和可變的報告格式。北京進口分析儀采購

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.

Determine the instrument blank.

a. Login a minimum of 3 Blank replicates.

b. Press the Analyze button on the instrument screen. After a short delay, the loading head slide-block will open.

c. Press the Analyze button on the instrument screen again, the loading head slide-block will close and the lower electrode will open.

d. Clean the upper and lower electrode manually, or, if applicable, remove thecrucible and press the analyze button to clean with the automatic cleaner.

e. Firmly place a graphite crucible on the lower electrode tip.

f. Press the Analyze button on the instrument screen, the lower electrode will close and the analysis sequence will start and endautomatically.

g. Repeat steps 2b through 2f a minimum of three times.

h. Set the blank following the procedure outlined in the operator's instruction manual.

Summary

The determination of the amount of oxygen, nitrogen, and hydrogen in iron, steel, nickel-, and cobalt-base alloys represents some of the most important quality metrics for these materials. Oxygen is used to create steel from pig iron by removing excess carbon. Oxygen content must be controlled to limit the amount of carbon monoxide that can be formed during solidification which may cause excessive porosity. Nitrogen is considered both an impurity as well as an important alloying agent. Itcan be present as a nitride or interstitially in its gaseous form. Increased nitrogen content is known to increase yield and tensile strength, thus decreasing ductility and formability. Excessive levels may evolve during solidification thus increasing porosity. High hydrogen content is the primary cause of embrittlement, blistering and flaking due to its high

mobility through the lattice and provides no potential alloying benefits. 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.
