Epsilon 4

Flexible configurations: Epsilon 4 is a highly flexible analytical tool available in a 10-Watt version for elemental analysis (F – Am) in areas from R&D through to process control. For even higher sample throughput or extended light-element capabilities and in more challenging environments, a 15-Watt version is available, which can even analyze carbon, nitrogen and oxygen.

Latest developments: Epsilon 4 instruments combine the latest excitation and detection technologies with state-of-the-art analysis software. The 15-Watt X-ray tube in combination with the high current (3 mA), latest silicon drift detector SDD30 together with the compact design of the optical path, deliver even better analytical performance than 50-Watt power EDXRF and even benchtop WDXRF systems - with the added bonus of power efficiency.

Fast and sensitive: Fast measurements are achieved by using the latest silicon drift detector technology that produces significantly higher intensities. Unique detector electronics enable a linear count rate capacity to over 1,500,000 cps (at 50% dead time) and a count rate independent resolution typically better than 135 eV for better separation of analytical lines in the spectrum. This allows the Epsilon 4 spectrometer to run at full power and therefore realizes a much higher sample throughput compared to traditional EDXRF benchtop instruments.

Reduce helium consumption: The high performance of Epsilon 4 enables many applications to be operated in air atmosphere, without longer overhead time and costs involved for helium or maintenance of the vacuum system. When measuring in air, low-energy X-ray photons characteristic of sodium, magnesium and aluminum are sensitive to variations in air pressure and temperature. Built-in temperature and air-pressure sensors compensate for these environmental variations, ensuring excellent results whatever the weather.
