QuSpectra mark QuSpectra NASA SBIR Awardee
Portable quantum sensors

Molecular analysis,
anywhere.

We bring NMR capabilities into a portable format. No superconducting magnets, no liquid helium, no dedicated facility infrastructure.

Powered by diamond quantum sensing, QuSpectra delivers high-sensitivity molecular analysis from very small sample volumes.

Capabilities

One sensor, two modes

What is it?

Chemical analysis

Identify compounds and concentrations across liquid samples— no reagents required.

Is it there?

Quantitative detection

Screen for compounds at trace concentrations — at the point-of-need, far from any laboratory.

How it works

From sample to fingerprint, in three steps.

The unique stack

Our integrated system controls and reads the quantum sensor. Changes in the magnetic field sensed by the diamond are read by the optical detector.

01

Diamond Quantum Sensor

Detects weak magnetic signatures from samples.

02

Integrated Microfluidics

Handles and positions samples directly on the sensor. No preparation, no reagents, no consumables.

03

Spectral Processing

Converts optical readout into molecular fingerprints.
