Vacuum purity that doesn't compromise your data
Mass spectrometers, leak detectors, and electron microscopes all depend on one thing above all: a vacuum environment free of hydrocarbon contamination. A single trace of backing-pump oil can register as background noise, distort a spectrum, or silently degrade a detector over months of use.
— Application Scenarios
Where scroll vacuum technology fits into analytical work
Dry scroll pumps back the instruments where contamination isn’t just undesirable, it’s disqualifying for the result.
01
Mass Spectrometry
Backing the foreline of GC-MS and LC-MS systems, where any hydrocarbon signal shows up directly in the spectrum baseline.
02
Helium Leak Detection
Fast, clean roughing for leak detection systems that need to reach test vacuum quickly without introducing false signals.
03
Electron Microscopy
Low-vibration backing for SEM/TEM chambers, where mechanical noise from the pump can directly degrade image resolution.
— WHY IT MATTERS
Clean vacuum. Precise results.
Analytical instruments demand vacuum solutions that are free of oil, particles and vibration. Our scroll technology ensures a contamination-free environment for accurate, repeatable analysis.
Advanced vacuum technology is crucial to maintaining the contamination-free environments required for analytical work.
Analytical applications leave no room for compromise. Even the tiniest contaminants or vibrations can affect measurement accuracy and instrument performance.
With nearly 20+ years of expertise, GEOWELL delivers reliable, oil-free vacuum solutions trusted by leading instrument manufacturers and laboratories worldwide.
