Procedure - Solid Samples

Instrument calibration/drift correction.

Add approximately 0.05 g of *** Graphite Powder to a *** Graphite Crucible.

Firmly place the crucible on the lower electrode tip or appropriate autoloader position.

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

Repeat steps 3b through 3j a minimum of three times for each calibration/drift standard used.

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

Procedure – Powder/Chip Samples

Determine the instrument blank.

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

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

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

Instrument calibration/drift correction.

Login a minimum of three Standard reps.

Weigh approximately *** grams of a calibration/drift standard into a *** Nickel Capsule; enter the mass and standard identification into appropriate rep fields. If applicable, place the nickel capsule in the appropriate autoloader position.

氧和氮空白值超過(guò)20。這是由于氣流小，不能將爐子中的空氣驅(qū)趕出去?？烧{(diào)節(jié)氣體流量，調(diào)節(jié)載氣壓力在0.2~0.4MPa。接通儀器載氣，放一個(gè)石墨坩堝在下電極上，打開(kāi)主電源開(kāi)關(guān)，點(diǎn)擊軟件上的關(guān)爐按鈕，關(guān)閉爐子并等待10s。調(diào)節(jié)流量調(diào)節(jié)器，直到流量計(jì)a顯示為30L／h，打開(kāi)爐子。調(diào)節(jié)調(diào)節(jié)器直到流量計(jì)b顯示為50L／h，再次關(guān)閉爐子。如果以上設(shè)置不穩(wěn)定，則增加流量至100L／h，反復(fù)調(diào)節(jié)直至儀器穩(wěn)定。

Procedure - Solid Samples：

--Instrument calibration/drift correction.

Place the nickel basket containing the calibration/drift standard into the open port at the top of the loading head.

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

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