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.

736 Series: Oxygen/Nitrogen by Inert Gas Fusion

The 736 family of Elemental Analyzers is designed for routine measurement of oxygen and nitrogen content of

inorganic materials, ferrous and nonferrous alloys, andrefractory materials using the inert gas fusion technique.

These instruments feature our Cornerstone brand ® software, a custom interface designed specifically for

touch-screen operation. Developed by combining longterm research with customer feedback, this easy-to-use

software gives you complete access to instrument control, analysis settings, diagnostics, reporting, and more—without sacrificing valuable bench space.

可選六軸可旋轉觸摸屏幕，增強了操作的工效和直觀性。

隨著現在科學技術的發展，儀器儀表行業發生了突飛猛進的發展，再加上當前計算機技術、網絡技術的進步和發展，組建網絡而構成實用的監控系統，可以提高生產效率和共享信息資源方向發展。當前儀器儀表行業產品發展呈現微型化、多功能化、智能化、網絡化四大發展趨勢。我國現有有限責任公司（自然）企業數千多家，已經形成門類品種比較齊全，具有一定技術基礎和生產規模的產業體系。但同時業內行家也指出，雖然我國測試儀器產業有了一定的發展，但遠遠不能滿足國民經濟各行各業日益增長的迫切需求。隨著手機移動網絡的消費潛力不斷隱現，消費者利用手機消費的頻率和份額逐年遞增。移動互聯網所隱藏的商業價值被更多地挖掘出來之后，各種傳統行業（包括光譜儀，色譜儀，質譜儀，樣品前處理行業）的移動網上平臺相繼誕生。中國服務型正面臨百年未有之大變局，行業行家認為，中美貿易戰不會有終點，中美關系時好時壞將成為常態，儀器儀表行業無法排除大局勢的影響，且不要把問題聚焦在關稅上。中國經濟的高速發展得益于WTO框架下的全球化分工;現在中國制造的競爭力在于工業門類齊全、供應鏈完整、供應鏈的高度專業和細分。北京美國LECO分析儀優惠價格
