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.

Sample Preparation

Sampling and sample preparation of refractory metals such as titanium and zirconium is somewhat different from that of steel. Unlike steel samples, hydrogen is not as mobile in this group of materials; therefore, storage in liquid nitrogen or dry ice is not required. However, it is important to keep the sample cool when cutting or sectioning. Sample preparation for oxygen and nitrogen determination has beendifferent from that of hydrogen determination.

氧氮?dú)浞治鰞x的常見(jiàn)故障及解決方法

供電正常、通訊正常，點(diǎn)擊確認(rèn)鍵后分析儀不工作。這是沒(méi)有水流，爐子溫度太高或儀器通道電壓不正常。如沒(méi)有水流，爐子溫度太高這些信息會(huì)顯示在顯示器畫面上，但沒(méi)有信息顯示說(shuō)明這兩項(xiàng)正常。接下來(lái)檢查儀器通道零位電壓，如果比±3V高出1V以上，可能是因?yàn)闅馄靠樟耍蛘呤强諝膺M(jìn)入到分析儀中。檢查并更換化學(xué)試劑，如果有空氣進(jìn)入熱導(dǎo)池里，熱導(dǎo)池的電壓就會(huì)＜-6V，此時(shí)打開(kāi)右面的門，堵住爐子氣體進(jìn)口，10s后，熱導(dǎo)池電壓值必然升高。經(jīng)過(guò)逐一排查，**終確認(rèn)堿石棉有問(wèn)題，更換后儀器正常。 美國(guó)分析儀廠家直銷
