Maximum precision and excellent lifetime in mass spectrometry

This high-precision sample manipulator has been specially developed for highly sensitive analyses in mass spectrometry with the best possible lifetime. For a material testing, this manipulator reaches even the smallest samples on one arm into a vacuum chamber and prepares them there with the laser. The sample moves in the plane by a few millimeters and inspects it with high precision in the submicrometer range.

Ideal for high-precision sample analysis in the mass spectrometer

Analyses in the smallest space at a top speed of 3.3 mm/s

Reliable results due to absolutely rigid, stable and precise positioning at ± 2.5 µm

Superior durability in demanding environments at over 1 million cycles

Optionally expandable:

Different travels
Individual solutions for cable routing
Configurable for clean room ISO 14644-1 (up to class 1 on request)
Combination with other systems for even more application possibilities
Immediate use with pre-configured controller incl. exemplary software

Ultra-precise analysis of smallest samples

To position the actuators outside the vacuum chamber, the sample arm is surrounded by a metal bellows. This flexible bellows is displaced by the drives outside the chamber.A purely linear movement in two directions was not possible due to the low flexibility of the metal bellows in transverse direction. Instead, a linear movement and a rotation around a pivot point 100 mm away from the sample were combined with a solid state joint.Both directions of movement are driven by stepper motors which act on sliding screw drives. The backlash of the ground sliding threads is largely suppressed by means of global spring preload.

Individual extensions and customizations

Engineering services include the fitting of the systems to your structure and the desired controlls. Furthermore, we develop prototypes and like to adapt the systems to the environmental requirements of your application particle emission, radiation, temperature, precision special parts manufacturing, working height, collision protection, safety concept, compensation factor and filter, sensor mounting, brake, decoupling, special lubrication, special colors, holders, adapters, special motors with pharmaceutical approval, comprehensive documentation, test protocoll, llife cycle tests

Applications with exceptionally high sample complexity

This high-precision sample manipulator can be easily combined with existing systems, resulting in a wide range of applications, such as

Identification of biomolecules e.g. proteins and peptides, oligonucleotides or oligosaccharides
Analysis of active substances, e.g. drugs, medicines, doping substances, cosmetics or chemicals in the organism
Examination of tissue sections and tumor spread
Age and origin analysis
Identification and quantification of components in complex mixtures such as environmental contaminants
Inspection of the precision of circuits in the semiconductor industry
Explosives detection on clothing and luggage at airports and for other security systems
