What remains in the chamber before the process?
Examine residual gases before introducing process gases. Compare conditions and investigate changes more precisely.
The next generation of vacuum measurement
Understand
vacuum.
We are developing TOF300: pressure and gas composition in one compact instrument. A new way to see what is happening inside your chamber.
For equipment manufacturers, industry and research.
TOF300 · Product vision
01 / The differenceOne process. Three insights.
All three insights come from real measurements. With our working demonstrator, we tracked gas composition during pumpdown, at base pressure and while introducing process gases.
Development status02 / Making gases visibleInteractive explanation
What is happening
inside my chamber?
Pumping down, testing a seal, assessing cleanliness: three examples show what additional gas information can bring to everyday work.

How is the residual gas changing?

Pressure trendrelative
The composition changes too.
The chamber is being pumped down.
The pump removes gas. The highlighted bar shows water in the residual gas; its signal is initially strong.
What do the signal assignments mean?
The horizontal axis shows the mass-to-charge ratio (m/z); bar height shows relative signal intensity. Assignments are simplified: signals from different gases can overlap, and molecules can form fragments. For example, the signal at m/z 28 may come from nitrogen or carbon monoxide. An individual peak therefore does not automatically identify a substance or prove a leak. The pressure trend has its own relative scale; the signal heights shown do not indicate concentrations.
03 / TOF300Our product vision
The housing and display are concept designs.
More insight. Fewer barriers.
As familiar as
measuring pressure.
We want to bring gas information to where it is needed: right at the chamber and into everyday work.
- 01
Measure base pressure. Understand residual gas.
Track total pressure during pumpdown, determine base pressure and see which gases are present: TOF300 is being developed to combine all three in one instrument.
- 02
Make information clear
Our aim is to turn spectra into clear trends and useful guidance for each application.
- 03
Designed for regular use
Compact sensing, electronics and software as one integrated instrument. Easy operation is a key development goal.
Our technical targets.
Development targets- Total pressure measurement
- down to 10−10 mbar
- Follow the pressure trend down to the achieved base pressure.
- Mass range

04 / TOFX technologyHow it works
Gases leave
a measurable trace.
Our technology uses time-of-flight mass spectrometry. It separates gas signals by their mass-to-charge ratio, adding a new perspective on vacuum.

01 / Ionisation
Gas is ionised.
Electrons ionise gas molecules. Electric fields can move the positively charged ions.

For everyone who wants to know
what happens in their chamber.
Wherever vacuum is part of everyday work, gas composition can reveal more of the picture. These applications guide our development.
Equipment and
component manufacturers
What can a chamber test reveal?
Alongside base pressure, unusual gas signals could indicate leaks or contamination, providing a starting point for further checks.
Research and
development
What conditions accompany the experiment?
From a single vacuum setup to an entire institute: gas information is intended to help researchers better understand experimental conditions.
Space and
New Space
What do materials release under vacuum?
Track gas composition during thermal-vacuum tests for additional insight into outgassing and the cleanliness of the chamber and test article.
Semiconductors
What remains between two process steps?
Examine residual gases and changes after venting, maintenance or process changes. For a better understanding of conditions in the chamber.
Requirements vary between systems. TOF300’s suitability will be tested for each application.
