新疆分析仪哪家好

氧氮氢分析仪的原理：分析样品在惰性气流存在下于石墨坩埚中加热熔融，其中脉冲炉温度可自由设定，并通过一个非接触式的光学温度传感器进行实时监控，用于实现样品的完全分解，反应所生成的CO H2和N2被带入到具有高稳定性和灵敏度的检测系统进行检测。对于CO的检测采用的是非色散性红外检测器，对于N2和H2的检测则采用热导检测器。

氧氮氢分析仪的特点：快速准确分析，自动化操作；精密气体校准；CO红外检测器，高分辨率和重现性的N、H热导池检测器；同一台仪器实现熔融提取和热提取；热提取分析时间可调；可自由选择温度*高达2500 °C；光学温度计温度测定和控制；所有检测器自动调零/自动水平控制（ALC）；数据评估的自动优化选择范围；炉自动清洁和坩埚自动进样（可选）；外设电脑进行操作和控制；样品信息保存； 所有样品数据可追踪查询；通过FTP或本地局域网进行数据传输； ON，H分析轻松切换。

Sample Preparation

Sampling and sample preparation is an important issue because traditional methods used to obtain samples for oxygen and nitrogen determination are different from those recommended for hydrogen, especially when sampling molten metal. The main difference in steel sampling procedures for oxygen/nitrogen and hydrogen is due to the mobilityof hydrogen. Special precautions must be used when sampling for hydrogen. From molten steel and iron, a sample must be quickly quenched in cold water and chilled in a refrigerant such as liquefied nitrogen or a mixture of acetone and solid carbon dioxide in order to reduce losses of hydrogen from diffusion. Losses of oxygen and nitrogen from diffusion are not a problem. A sample that is taken for hydrogen and

chilled in a refrigerant can also be used for oxygen and nitrogen determination. However, a sample that is typically taken for oxygen and/or nitrogen determination is not suitable for hydrogen determination due to hydrogen loss (diffusion). Surface contamination must be removed by filing or light grinding, using care not to overheat the sample.

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.

Note: LECO Reference Materia***o not require preparation. See preparation statement on the reference material certificate. Solid Standards may be used to calibrate when chip or powder standards are not available.

Procedure – Powder/Chip 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 3i a minimum of three times for each calibration/drift standard used.
