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. 安徽分析儀哪家好通用下電極坩堝支座，容納各種坩堝使用。

Determine the instrument blank.

a. Login a minimum of 3 Blank replicates.

Oxygen, Nitrogen, and Hydrogen in Refractory Metals

Summary

One of the most critical chemical specifications of titanium alloys is the hydrogen content. Too high of a

hydrogen content can cause hydrides to precipitate, which can lead to embrittlement and subsequent

cracking when the alloy is stressed. Hydrogen pickup typically occurs during downstream processing steps

such as heat treating, pickling, and cleaning.

The LECO ONH836 is a simultaneous oxygen, nitrogen, and hydrogen determinator that utilizes an electrode furnace, inert carrier gas, and both infrared and thermal conductivity detection to meet the analytical needs of the refractory metal industry. 

This application note was written specifically for use with the LECO ONH836 series determinator.
