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.

New ceramic crucibles
Yttria and Yttria Stabilized Zirconia (YSZ) crucibles for TG-DSC and TG-DTA versions, with optional covers are available. The crucible’s volume is 100 µL, diameter 5mm and height 8mm.

特征

炉体
SetsysEvolution装备了耐用且高性能的石墨炉体,提供高扫描速率(100°C /分钟,全部温控范围内)及实验进行时控温条件的快速切换。单一石墨炉体即可实现室温至2400度的全程控温。通过更换控温热电偶可快捷实现最高温度控制 切换(1000°C,1600°C,或2400°C)。 Setsys Evolution具有初级及二级真空装置。

气氛环境
SetsysEvolution 配备的 高性能气体控制面板,通过质量流量控制器确保气氛及混合气体高精度。可实现多种气氛控制需求,SetsysEvolution标配型号在1750°C条件 下可实现任意种类气体气氛中正常工作。高于1750°C,炉体保持不变仅需配置少量附件就可轻松满足最高达到2400度的实验需求。
气氛包括0至100%任意浓度的H2, CO2, NH3 ,可选附件如下:
– 氢气安全组件
– 腐蚀性气氛组件(可评估材料在100%腐蚀性气氛下性能)见技术备忘表 TN679 
– 氟气氛组件
– 湿度气氛组件-见湿度发生器 WETSYS (79°C时产生0~90%湿度的载气,最高可用于1750°C条件下,适用气氛含空气,He,N2,CO2,等,可程序控制湿度条件)

对称结构天平
SetsysEvolution采用的特殊设计悬挂式对称结构天平特别适用于TGA应用。主要特点包括:
• 测试样品重量范围广(mg~35g)
• 可检测长时间实验下的微小重量变化
• 高灵敏度
• 同等实验时间及温度条件下具有领先于市场的基线稳定性

电子器件及软件
SETSYS Evolution随机装备功能最强大,用户操作最友好的热分析软件-CALISTO.
