RKI Instruments has introduced the Model AC-2 photoelectron spectrometer.
Designed for atmospheric pressure operation, it consists of an open counter equipped with a UV source.
The instrument measures ionisation potential and work function of surfaces in air (without vacuum).
The open counter is a unique electron detector which can be operated in open air (without vacuum) and has been used for photoelectron spectroscopy in the air (Pesa).
By combining the open counter with a UV source, the AC-2 Pesa instrument opens the way to a new dimension in surface anaylysis.
The AC-2 is capable of measuring large samples up to 50x50mm, powder samples and films on a surface.
Measurements can be taken is just five minutes.
Other methods which require vacuum may take up to 30 minutes for a measurement.
Any sample that emits photoelectrons can be measured.
Samples include metals, semiconductors, organics, magnetic and polarized materials as well as catalysts, pigments and ceramics.
RKI Instruments is an instrument company located in Union City, California.
The Model AC-2 is manufactured for RKI by Riken Keiki of Tokyo, Japan.
Riken Keiki has been a world leader for gas detection and other instrumentation for over 60 years.
