Cahn VersaTherm热重分析仪
High Mass - High VolumeThe electromagnetic nulltype balance is the heart of this thermogravimetric analyzer. The VersaTherm HM (High Mass), with a sample capacity of 100 g, provides 1 µg sensitivity. The ability to handle high mass and high volume samples can be critical. Often, complete parts like microchips and ball bearings must be measured. Coatings can be analyzed using the entire coated part, which improves accuracy and minimizes sample preparation. The high mass and high volume capability of the Cahn VersaTherm provides a tremendous advantage with non-homogeneous, low density, or irregularly shaped samples.SoftwareData acquisition and data analysis are done with the powerful Thermo Scientific Thermal AnalystTM software from Thermo Scientific. Compatible with Microsoft® Windows® NT, 2000 or XP, it provides the ultimate in flexibility and reliability.
Featuring:
Real time and continuous data display
Data saved directly to hard drive for nearly endless runs
Programmable control of gas flow rates, switching, and mixing
A complete suite of powerful data analysis toolsThe optional TG/FT-IR software offers:
Complete integration of data analysis and acquisition with the Thermo Scientific OMNICTM FTIR software
Programmable external AC and contact closure for remote start of FT-IR or Mass Spec
High Vacuum – 5 x 10–5 torrThe Cahn VersaTherm HS (High Sensitivity) and HM (High Mass) can be evacuated down to 5 x 10-5 torr using the optional vacuum accessory. This guarantees an oxygen-free environment and fast purges.Corrosive or Reactive GasesCorrosive or reactive gas environments including SO2, HCL, H2, CH4, O2 and H2S can easily damage thermal analysis systems. Our TGA instruments are designed to handle the most aggressive sample environment by incorporating a unique patented gas flow separation system and gold plated balance mechanism for added protection.High Precision – High SensitivityThe Cahn VersaTherm HS (High Sensitivity) provides sensitivity of 0.1 µg. The wide dynamic range of this instrument makes it possible to measure trace components in very high purity materials.High VolumeHigh volume is important when analyzing low density materials to maximize surface area exposure and prevent spillover contamination during out-gassing. The Cahn VersaTherm TGA provides unique, high-volume reactor tubes and sample containers up to 35 ml to accommodate these "real-world" samples.
High MassSample mass is a vital factor when analyzing non-homogeneous materials such as coal, minerals and catalysts. The Cahn TGA offer's unique, high-mass capability up to 100 g.Patented Synergy Interface for TG/FT-IR/MSThe patented Synergy interface uses a large ID "sniffer" tube to guarantee maximum gas transfer with minimal clogging. The no-flow zone guarantees minimal off-gas mixing, and the "sniffer" tube is positioned right above the sample to provide concentrated effluents.
