ESCO, Ltd.: The Global Specialist in Ultra-High Vacuum Thermal Desorption Spectroscopy
Based in Japan, ESCO, Ltd. is a highly specialized manufacturer exclusively dedicated to Ultra-High Vacuum Thermal Desorption Spectroscopy (UHV-TDS) instruments—a unique level of specialization that is rare anywhere in the world. The origin and foundation of our analytical innovation is the ESCO-TDS1200II IR, our flagship base model that established the global benchmark for high-precision UHV-TDS. Operating under strict UHV conditions (<10^-7Pa) with Quadrupole Mass Spectrometry (QMS), concentrated IR lamp heating up to 1200°C, and cryo-chamber technology (minus 100°C), it effectively eliminates background noise—such as residual water molecules (H2O)—to achieve absolute trace hydrogen quantification. This foundational philosophy forms the core engineering DNA behind our entire analytical lineup.
At the upcoming exhibition in Germany, ESCO is proud to showcase our specialized lineup evolved from this core origin, covering an unprecedented temperature spectrum—from cryogenic (minus 100°C) to ultra-high temperatures (1700°C):
■ ESCO-TDS 600 IR H2 [Exhibition Highlight]: Featured as our primary exhibition highlight for the German market, this practical analyzer bridges the ultra-high sensitivity of lab-grade mass spectrometry with the simple "one-touch" workflow of factory-floor equipment.
- ppb-Level Sensitivity with UHV Precision: Operating under UHV, it detects minute traces of diffusible hydrogen down to ppb (parts per billion) levels without complex vacuum sample transfer mechanisms.
- High-Speed Sampling (1 Hz): Sampling once per second—300 times faster than conventional atmospheric gas chromatography (GC) systems—it captures peak temperatures without missing sharp desorption peaks even under rapid heating conditions (up to 600°C/h).
- Elimination of Secondary Reactions: The strict UHV environment eliminates carrier-gas-induced and moisture-induced secondary reactions, ensuring pure hydrogen desorption data for evaluating delayed fracture (hydrogen embrittlement) in ultra-high-strength steels and optimizing baking processes in electroplated films.
■ ESCO-TDS-100 Cryo H2 [Under Development] (Low-Temperature TDS / L-TDS): Engineered as a world-exclusive "Cryogenic Diffusible Hydrogen Analyzer," this system measures from minus 100°C to 200°C. It is the only instrument globally capable of quantitatively separating and detecting hydrogen trapped in specific individual lattice defects—such as vacancies (HESIVs), dislocations, and grain boundaries—within pure iron and advanced steels.
■ ESCO-TDS 1700 IH (Induction Heating TDS): Engineered for ultra-high-temperature analysis exceeding 1500°C via high-frequency induction heating, providing breakthrough analytical capabilities for extreme applications:
- Nuclear Fusion Materials (Tungsten): Evaluates the trapping, retention, and permeation behaviors of hydrogen isotopes (H, D, T) in plasma-facing components (divertors and first walls) under extreme thermal loads.
- Carbon Materials (Graphene, Graphite, & Carbon Black): Quantifies edge-terminated hydrogen desorbed at elevated temperatures (>1000°C) to evaluate active edge site density, degree of graphitization, and electrochemical durability in batteries and fuel cells.
■ ESCO-TDS1200II IR BGM [New / MEMS & Semiconductor Model]: Accurately measuring the temperature of silicon in a vacuum has historically been a major technical challenge. By integrating an optical Bandgap Monitor (BGM), this system achieves direct, highly precise in-situ silicon temperature tracking, making it the ideal R&D tool for silicon-based MEMS sensors, semiconductor devices, and oxide thin films.
ESCO’s TDS systems are indispensable across high-tech sectors, including MEMS/semiconductors, hydrogen energy, nuclear fusion, fuel cells, lithium-ion batteries, automotive high-strength steels, and electroplating quality control. We invite you to visit our profile and booth to discover how the world's premier TDS specialist can elevate your research and production process evaluations.
