STA HP TGA-DSC (STA Simultaneous Thermal Analysis)

Product catalog summary

Introduction
The document introduces the High Pressure Simultaneous Thermal Analysis (STA) instrument, which operates under defined atmospheres and pressures up to 150 bar, with a temperature range from room temperature to 1800°C. It is noted for its high precision, resolution, and long-term drift stability, making it unique in the market.

Specifications
The STA Platinum Series combines Thermogravimetry (TG) and Differential Thermal Analysis (DTA) or Differential Scanning Calorimetry (DSC) to provide comprehensive data on mass change, enthalpy, specific heat, and other thermal properties. The instrument supports various applications, including pyrolysis studies, gasification, CO2 sequestration, and metal reduction/oxidation studies.

Technical Features
The STA HP is controlled via PC software compatible with Microsoft Windows, featuring data security, curve comparison, data export, and multi-method analysis. The TG features include mass change evaluation, while HDSC features cover glass transition temperature and complex peak evaluation.

Measurement System
The Linseis STA HP is the only system providing TG and DTA/DSC data under pressurized conditions up to 1800°C. It supports high vacuum, inert, reducing, and humidified atmospheres, with a unique gas control for high-pressure applications.

Applications
An example application is the gasification of charcoal under CO2 atmosphere at 20 bar, demonstrating the instrument's capability in high-pressure environments.

Models and Specifications
Two models, STA HP/1 and STA HP/2, are detailed with differences in temperature range, heating elements, pressure range, and TG resolution. The document also compares calcium oxalate decomposition under pressure versus atmospheric conditions, highlighting pressure dependence.

Contact Information
Contact details for LINSEIS GmbH in Germany and LINSEIS Inc. in the USA are provided, along with a list of products and services offered by the company.

STA HP TGA-DSC (STA Simultaneous Thermal Analysis)-2

Introduction Thermogravimetry is a technique in which the mass under defined atmosphere and pressure (up to 150 bar) of the sample is monitored against time or temperature in the temperature range RT...1800°C. This instrument is while the temperature of the sample, in a specified worldwide the only available pressure STA. atmosphere, is programmed. This technique serves the determination of material compositions. The unique characteristics of this product are high precision, high resolution and long term drift stability. The STA Platinum Series was especially developed to meet the challenging...
