Sample observation STA/GC-MS
Sample Observation STA–Gas Chromatography Mass Spectrometry Measurement System
Successfully measured the water content of asteroid “Ryugu” samples collected by Hayabusa2 (measured at Tokyo HQ, August 4, 2021).
Simultaneous TG–GC-MS measurement while directly observing the sample during heating In addition to mass changes associated with thermal reactions, it provides high-sensitivity chemical reaction information that cannot be fully obtained through thermal analysis alone. Compatible with MS and GC-MS systems from various manufacturers, it serves as an essential tool for advanced materials research, process development, quality control, and basic science. Measurements under water vapor atmosphere are also supported.
Sample observation STA/GC-MS Overview
■ Innovative evolved gas collection mechanism
Collects gases directly from near the sample while minimizing background levels of water and air.
■ Rich simulation functions and accurate temperature information
Offers wide flexibility in measurement conditions—heating, atmosphere, and sample amount—while providing accurate sample temperature information.
Mass change data from STA and chemical reaction data from GC-MS can be obtained simultaneously, allowing in-situ (on-site) observation of reaction progress.

Sample observation STA/GC-MS Options
The following accessories are available for this product:
ASC for STAvesta
Optional ASC (Auto Sample Changer) for greater throughput Upgradeable with ASC for automated measurements
STAvesta ASC Safety cover
The ASC safety cover is designed to reduce mechanical hazards associated with the automatic sample changer (ASC).
Gas Selector
Links to the measurement program and switches the gases flowing into the sample chamber.
Flow Meter
The flow meter controls the flow rate of the atmospheric gas (inert gas, air, etc.) supplied to the sample chamber.
Sample Pan
Depending on the sample to be measured (especially if the sample is metal), it may melt the sample pan and damage the sample holder or other parts of the instrument.
