AMS 1300

The Atonarp Mass Spectrometer 1300 (AMS 1300) is the industry’s first ever quantitative real time miniaturised mass spectrometer for gas detection. Now, you can monitor not only the most minuscule traces of gases, but also the precise quantity of each for optimised process control. With a rugged Faraday Cup and calibration against the Capacitance Diaphragm Gauge (CDG), the AMS 1300 operates in high pressure environments without the need for external pumps. Its customisable proprietary software puts precision molecular analysis for a range of industrial applications at your fingertips.


Monitor primary and secondary end points, silicon oil contamination and in-line vaccum leaks. Purpose-built for Lyophilisation Process Control.


Ensure efciency and compliance with Vaccuum and Transfer Chamber Monitoring, Leak Detection, Atmospheric Pressure Gas Analysis and more.


Enhance custody chain assurance with real time quantitative gas composition and calorific value data.


Quantitatively detect vapors of target molecules and compounds of interest at security check-points to flag potential hazards.

AMS 1300: The most durable, accurate, cost-effective and hassle-free tool for process analytics.

Small and Powerful

Compact, sleek and as small as a toaster, the AMS 1300 can be easily retrofitted on to any machine. Ideal for process and machine control applications, it’s fitted with our proprietary miniaturised array of micro-quadrupoles with integrated small turbo and roughing pumps.

Get real data in real time

The AMS delivers highly accurate measurements (sub-1%) due to its innovative electronics and signal processing capability. It performs quantitative molecular scans in less than 10ms, allowing for real-time process control optimization. And, with its cloud-connected software, you can leverage the data analytics for unparalleled process insight.

Optimise high pressure performance

The AMS operates at ~3 orders of magnitude higher pressure compared to standard mass spectrometers, thanks to the miniature design of Atonarp’s mass spectrometer array of micro-quadrupole rods, allowing for simpler system integration solutions.

Work with molecular precision

Ideal for fast repeatable measurements needed in process control applications, AMS spans 6+ decades of dynamic range and down to ppm concentration levels. It is calibrated within the same pressure range against the gold standard Capacitance Diaphragm Gauge (CDG).

Experience unparalleled uptime

With a smart modular design, the AMS 1300 guarantees the industry’s lowest downtime, with easy on-site replacement of consumable parts and in-built usage diagnostics. Few required consumables and low lifetime maintenance translates into a low total cost of ownership, and hassle-free operation.

AMS 1300
16 Poles, 9 Quadrupoles

Miniaturized quadrupole arrays contain smaller rods, and more quadrupoles, than a conventional quadrupole detector.

Traditional MS
4 Poles, 1 Quadrupole

The standard-sized array is unable to operate at high pressure and requires external pumps which are space-consuming.
