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.
氧高低双量程采用3个碳红外检测一氧化碳和二氧化碳，保证准确定量。山东美国LECO分析仪价格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.
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.
