Protect Your Investment!


The QSN-750 II is often compared to its “little brother”, the GS-1000-II. However, unlike the GS 1000-II, the QSN 750-II can be used within automate production environments. When the spectrometer is combined with a sample-preparation device and a sample-handling robot, it can form a single unit, and can ensure automatic cleaning of the counter-electrode.

Custom Specifications

Both the integration system and the photomultipliers, which are arranged in accordance with customer specifications, are housed inside the optics and are therefore protected against external influences.

Easy Maintenance

The easy-to-reach self-cleaning and patented spark stand and aperture window enable problem-free maintenance by the user. An exhaust filter ensures the consumed argon is purged.

Fast Measuring Process

The automatic program selection option simplifies assignment of the right analysis program. Depending on the application, the measured values appear on screen approx. 16-30 seconds after the start of the measuring process and can then be printed out, transferred within the network or evaluated later.

Analytical Constancy

The temperature-stabilised optics and the Gated Digital Source (GDS) technology guarantee a high degree of signal reproducibility and thus analytical constancy.

Simple to Use

Precise instructions on how to operate the QSN 750-II model and use the software are naturally given during installation. The customer only has to ensure availability of a power and an argon supply.
