SETSYS超高温热重分析仪

技术特点

高性能模块化热重分析仪(室温至2400°C

仪器亮点

SETSYS Evolution 是一款标准的高性能TGA、TG-DSC 及 TG-DTA热分析仪。它基于一个全模块化的热分析平台,可以实现TGA、DTA及DSC;同步TGA-DTA或TGA-DSC;热膨胀/TMA的测试。SETSYS TGA(热重分析)的关键技术是塞塔拉姆独有的对称天平,以及稳定耐用的炉体,可以提供完美的表现和极低的操作损耗。SETSYS可以配置最高温度达2400°C的实验温度,并可以使用相对湿度、真空以及高腐蚀性气氛。参见:

NEW PARTS AND OPTIONS
SETSYS Vapor Sorption
A new SETSYS Evolution TGA or STA version is available for studying the sorption behavior of materials with vapors (including volatile organic compounds). This allows for sorption isotherm or sorption kinetics experiments. Find out more by downloading TN707 from our application documents library at www.setaram.com.

Quenching / Fast heating
This option allows the sample to be inserted in, or removed from, the hot zone of the furnace during a measurement. The insertion and removal is programmed from the Calisto software.

Oxygen Trap
A gas purification system is available to remove trace oxygen from the inert / carrier gas flow. It is based on a zirconium foil placed in a slot in the hot part of the anti-convection tube above the sample.

Oxygen Partial pressure
This option allows for the measurement and control of oxygen partial pressure of the gas flowing above the sample. This is especially interesting when studying the phase diagrams of ceramics. An oxygen partial pressure controller is placed upstream of the test gas inlet. A specific flange equipped with an oxygen probe is connected at the furnace outlet.

Protected thermocouple
An alumina sleeved protected thermocouple was designed to prevent corrosion/damage from the gases evolved from the sample. It is available with or without the above mentioned oxygen probe. Various thermocouples types are available up to 1750°C.

Hook for disc shaped samples
Platinum based hooks which allow hanging of disc-shaped samples to the balance are available. Sample diameters vary between 10 and 16mm.

特征

炉体

SETSYS Evolution配置了耐用且高效的石墨炉体,提供超高升温速率(全温度范围内最高可达100 °C/min), 单个炉体即可满足从室温到2400 °C所有应用。简单快速的更换热电偶即可完成切换最高温度上限(1000, 16000, 1750 或 2400 °C)的操作。SETSYS Evolution同时还可配置初级真空和二级真空。

气氛

配置质量流量计(MFC)的高性能的气体控制系统可以确保气氛的精确控制及气体混合。此外还有多种气氛控制的选件。标准的SETSYS Evolution配置允许多种在多种气氛下加热至1750 °C。而在1750 °C以上,相同的炉体更换少许配件后可以加热至最高2400 °C。可以使用最高100%浓度H2、CO及 NH3气氛。可选配件:氢气安全系统、腐蚀气体套件(可以使用100%浓度的腐蚀气氛,参见技术文档TN679),氟化氢气体套件、湿度发生器WETSYS(可产生最高达70°C 下90%相对湿度气氛,最高使用温度1750°C,气氛包括空气、氦气、氢气及二氧化碳,并可编辑复杂的湿度条件,参见WETSYS。)

天平

SETSYS Evolution的对称型上悬挂天平是特别针对TGA应用设计的。其关键特性包括:

-毫克至35克的样品质量测试范围;

-超长的测试时间内可检测细微的质量变化;

-高灵敏度;

-无论以时间还是温度而言的世界领先的基线稳定性。

软件

SETSYS Evolution配备的同领域内最强大,使用方便的软件CALISTO。

应用案例

SETSYS Evolution是专为最苛刻的环境和长期的等温实验。它的应用包括研究金属和合金的氧化/腐蚀,材料和气体之间的反应,特殊气氛环境下的等温稳定性何金属的相转变等。
