When detecting leaks, it is important to distinguish between virtual and real ones. Examples of virtual leaks can be: gas desorption, diffusion, trapped volume, and back streaming. Leak-up or rate-of-rise tests can indicate whether a vacuum system's base…
Ionization gauges convert residual molecules to positively charged ions, and then attract them to a negatively charged collector where they create a measurable current. Modifications to high vacuum ionization gauges can optimize their performance at a…
No one gauge technology will provide pressure measurement throughout the range of vacuum. Combining vacuum sensors can produce a gauge capable of measuring pressure better than with any single technology. After having highlighted the properties of individual…
When choosing a vacuum gauge, it is possible to adopt high vacuum ionization gauges or sputter ion current. After describing the basic operating principle of the Sputter ion pump, this video shows how to measure UHV pressure with Agilent SIPs.
Material preparation and cleaning in ion pump manufacturing is critical to achieving ultrahigh vacuum pressures. One cleaning process to which the pump components are subjected is vacuum firing, through which the outgassing rate of the pump is reduced…

Customer feedback on turbo pumps often highlights concerns regarding the durability of these high-speed vacuum devices. However, users can take concrete steps to significantly enhance uptime…
To get an impression on the working pressure there are more parameters necessary like ID, eluent composition, fully or superficially porous particles used, ...
Hello,
What are you seeing on the axes? You can alter the axes by using the stacked mode so you might want to make sure that is not selected. What types of signals are you opening in DA?
