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。

Procedure – Powder/Chip Samples
Prepare the instrument as outlined in the operator's instruction manual.
Login a minimum of three Blank reps.
Press the Analyze button on the instrument screen. After a short delay, the loading head slide-block will open. Insert a *** Nickel Capsule (leave capsule open) into the open port at top of 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.
Procedure - Solid Samples
Determine the instrument blank.
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 3 Standard replicates.
Weigh approximately *** grams of a calibration/drift standard, enter the mass and standard identification into appropriate replicate fields.
Note: LECO Reference Materia***o not require preparation.See preparation statement on the reference material certificate.

Summary
The determination of the amount of oxygen, nitrogen, and hydrogen in iron, steel, nickel-, and cobalt-base alloys represents some of the most important quality metrics for these materials. Oxygen is used to create steel from pig iron by removing excess carbon. Oxygen content must be controlled to limit the amount of carbon monoxide that can be formed during solidification which may cause excessive porosity. Nitrogen is considered both an impurity as well as an important alloying agent. Itcan be present as a nitride or interstitially in its gaseous form. Increased nitrogen content is known to increase yield and tensile strength, thus decreasing ductility and formability. Excessive levels may evolve during solidification thus increasing porosity. High hydrogen content is the primary cause of embrittlement, blistering and flaking due to its high
mobility through the lattice and provides no potential alloying benefits. 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.

仪器仪表行业飞速发展一是因为我国的经济高速稳定发展的运行;按照过去的经验,如果GDP的增长在10%以上时,仪表行业的增长率则在26%~30%之间。二是因为我国宏观调控对仪表行业的影响有一个滞后期,仪表往往在工程的后期才交付使用,因此,因宏观调控政策而减少的收入对仪表行业的影响不会太大。进一步提升我国仪器仪表技术和水平,有限责任公司(自然)企业要顺应产业发展潮流,在稳固常规品种的同时,进一步发展智能仪器仪表,提升产业数字化、智能化、集成化水平。随着手机移动网络的消费潜力不断隐现,消费者利用手机消费的频率和份额逐年递增。移动互联网所隐藏的商业价值被更多地挖掘出来之后,各种传统行业(包括光谱仪,色谱仪,质谱仪,样品前处理行业)的移动网上平台相继诞生。中国服务型正面临百年未有之大变局,行业行家认为,中美贸易战不会有终点,中美关系时好时坏将成为常态,仪器仪表行业无法排除大局势的影响,且不要把问题聚焦在关税上。中国经济的高速发展得益于WTO框架下的全球化分工;现在中国制造的竞争力在于工业门类齐全、供应链完整、供应链的高度专业和细分。湖南进口分析仪
