Synchronous Thermal Analyzer (STA 2500 Regulus)

1、 Instrument Introduction:

Excellent performance

STA 2500 RegulusEfficient and reliable performance, with a wide temperature range.

Top mounted sample, unique self compensating differential balance design

The instrument is a top loading system with natural gas flow, which can automatically protect the balance from condensation deposition and contamination. This tailor-made microbalance system eliminates the effects of buoyancy and convection, making the operation simpler.

Diverse types of atmosphere

Measurement can be carried out under inert atmosphere, oxidizing atmosphere, and vacuum conditions. The atmosphere can be dynamic or static. Built in mass flow controller（MFC）Controlled by software, the gas flow rate can be changed and recorded at any time according to testing needs.

Suitable for analyzing escaping gases

STAThe top sample design facilitates the connection of gas analysis systems, such asFTIR(Fourier Transform Infrared Spectrometer),MS(Mass spectrometer), orGC-MS(Gas chromatography)-Mass spectrometry). At the same time as conducting thermal analysis, simultaneous analysis of the composition of the escaping gas can be carried out.

Sample tray, crucible, and nested platform

The instrument can be equipped with crucibles made of various materials such as alumina, platinum, aluminum, quartz, etc., and has different shapes and sizes to choose from.STA 2500 RegulusThe standard equipped nested platform supports almost all types of crucibles. A large volume crucible requires a larger fitting platform.

Used in conjunction with an escaping gas analyzer

BySTA 2500 RegulusGas analysis systems such asFT-IR(Fourier Transform Infrared Spectrometer)QMS(quadrupole mass spectrometer) orGC-MS(Gas chromatography)-Mass spectrometer can be used in combination to obtain samples at different times/Information on the type of escaping gas at temperature. From this, more detailed information about the tested material can be obtained, and even characteristic information about the material composition may be obtained.
