LEYSPEC ultra 200S

The LEYSPEC product family offers simple and intuitive operation with an on-board control and display unit. Simple residual gas analysis is possible without even connecting the device to a computer.

Due to the intuitive interface, the Residual Gas Analyzer (RGA) is very easy to operate. At the push of a button, you can display the partial pressures of key gases and if your process involves an additional gas, you can assign it to the spare display channel. Due to the high bake-out temperatures achievable, the RGA is ideal for use in demanding high vacuum and ultra high vacuum applications.

The LEYSPEC RGA offers greatest sensitivity combined with an intuitive software that allows all basic and advanced test procedures.


LEYSPEC for accurate measurement

Intuitive software
The intelligent and intuitive LEYSPEC software completes the offering. The easy user interface allows a wide range of use cases, from simple operations to complex analysis. Creating recipes is as easy as it should be: Quick and convenient. During operation the total pressure is displayed and different views can be chosen to fit the view for the purpose of the analysis. Choose between the scan mode, trend mode or analog mode.

Highest Sensitivity
The LEYSPEC product family offers the highest sensitivity for the most accurate residual gas analysis. This allows detecting even the smallest traces of contaminants or process gases.

Highest bake-out
With its high bake out temperatures of up to 300°C, the LEYSPEC ultra is perfectly suited for sophisticated high and ultra high vacuum applications. The LEYSPEC ultra range offers highest bakeout temperature so even in harsh environments reliable gas analysis can be performed.

Advanced feature
Preinstalled software functions allow many additional functionalities and test procedures such as a helium leak test or setting of warnings and error levels for selectable gases. A programmable degas function is implemented for simple process degassing after start or exposure to atmosphere. The background suppression allows focussing on the important peaks.

Different product types
The new LEYSPEC range offers the perfect solution for any application in mass spectrometry. Focusing on residual gas analysis the product range offers solutions for 100, 200 or 300 amu – depending on the process requirements. All products come with the integrated display for easy and quick operations as well as the LEYSPEC software for sophisticated test procedures and residual gas analysis. Compact in size and mountable in any orientation, the LEYSPEC product range is perfectly suited for different built-in situations.



  • Advanced range for all residual gas analysis
