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.

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.

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.

Software Features & Benefits

Cornerstone brand software is divided into four main sections—Analysis, Diagnostics, Settings, and Instrument—for simplified navigation and organization. Toolbars, sliders, and drop-down menus makeit easy to set parameters for calibration and data processing. The software also includes real-time ambient monitors, with fully animated system diagrams. Advanced diagnostic features include a thorough digital on-board manual, maintenance animations, photo illustrations, and screen captures that quickly provide the direction needed without having to refer to multiple manuals. also Cornerstone supports extended data archiving and flexible reporting capabilities. 双直流风扇保证持续冷却，不受电压波动的影响。江苏专业元素分析仪优惠价格

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.
