Creating Analytical Instruments Grounded
in Our Core Technologies

We primarily develop and manufacture thermal desorption spectroscopy (TDS) systems—also known as temperature-programmed desorption (TPD) in surface science—for materials evaluation, integrating mass spectrometry, high-vacuum engineering, precise temperature control, and gas analysis. ESCO, Ltd. systems enable precise detection of hydrogen, water, and other desorbed species under ultra-high vacuum across electronic materials and thin films, as well as metals, ceramics, and polymers.

We welcome inquiries such as “Could you design and manufacture an instrument like this?”, and such customer requests often become the starting point of our product development. We will continue to deliver analytical instruments that support manufacturing industries worldwide.
