A BRAVE new approach to particle analysis

BRAVE Analytics develops and delivers lab and PAT solutions for particle analytics. These are used in water and environmental analysis, for biotech applications and the pharmaceutical industry.
Customers come to us:

We have a patented and innovative measurement technology: OptoFluidic Force Induction (OF2i®) which is available combined with in-flow Raman analysis and can be coupled to an ICP-MS for complementary particle analysis.

Particle analytics with OF2i® + Raman

BRAVE Analytics introduces its particle analysis device which determines particle size and particle concentration and provides Raman analysis - continuously, in-flow and on a single-particle basis.

+ Raman analysis

The new and patented OptoFluidic Force Induction for nanoparticle characterization is the result of years of research and development but it doesn’t stop there. With OF2i® you can:

Adding the BRAVE B-Elementary Raman analysis module to the OF2i® lab device gives you unique particle analytics so you can:

In cooperation with an Austrian university, the coupling of an OF2i®+Raman laboratory device with an ICP-MS is currently being tested. The initial results are promising. Scientific publications and a product launch will follow. 


This is what our customers and partners say about us

Unmatched particle analytics

Benefits of OF2i® + Raman Analysis

Minimum sample preparation

Size, concentration and PSD measurements require only dilution; Raman analysis of particles e.g. microplastics in water needs no sample preparation at all.

Single-particle sensitivity

Detect single particles and see results based on every particle's individual properties.

Continuous measurement

Get a chemical analysis of your particles during flow and monitor sample behavior as it happens.

For challenging samples

Analyze polydisperse systems, ultra-low concentrations, aggregates, anomalies and large-particle tails.

Continuous detection and Raman analysis of particles

Adding a Raman analysis module to our nanoparticle analyzer makes it possible to measure particle size and particle concentration and also detect and analyze individual particles with Raman spectroscopy. 

This correlative OF2i®-Raman device detects particles that are difficult to access by standard Raman microscopy: 

BRAVE B-Elementary gives you the first-ever in-flow optical tweezers for chemical analysis and opens the door to coupling with ICP-MS.

Why BRAVE particle analytics?


Uses the revolutionary OF2i® principle with a unique in-flow Raman analysis.


Measures continuously and delivers a live data stream.


Provides measurement results based on single-particle sensitivity.


Delivers statistically valid results and not just average values.


Integrates into your production process as an online PAT sensor or into your laboratory workflows as a benchtop analyzer.


Delivers measurement data continuously and in real-time over a time you define (lab device) or 24/7 (PAT sensor).

Continuous & time-resolved particle analysis

With our OF2i® nanoparticle analyzer for the lab BRAVE B-Curious you can monitor sample changes as they occur in the measuring cell. BRAVE B-Curious measures up to 1000 particles per minute and delivers results representative of the whole particle population.

Track particle concentration and particle size over time to better understand sample kinetics such as:

After measurement, BRAVE B-Curious uses an automated self-cleaning cycle to save you time and effort.

There are no dumb questions.

OF2i® integrates directly into the manufacturing process as an online PAT sensor. It continuously delivers measurement data in real-time so you can check, adjust and optimize your production processes.

Our nanoparticle analyzer for the lab BRAVE B-Curious is available to order now. The online PAT sensor BRAVE B-Continuous is currently being optimized and tested together with selected partners and will be available in 2024.

OF2i® has single-particle sensitivity. It can even detect ultra-low particle concentrations, single large particles or outliers, e.g. a few nanoplastic particles in one milliliter of water.

Quickly available measurement data is one of OF2i®’s many strengths. As soon as the measurement starts you can see a live stream of the particles in the H.A.N.S. software and results are ready immediately.

Contact us at We will answer all your questions, offer a live demo either at your site or online and discuss further steps (including: a feasability study, comparison measurements, measuring campaign).

Yes, the lab device measures over minutes and even hours. As a PAT device BRAVE B-Continuous is made for 24-hour operation.

Absolutely. While established methods typcially deliver average values as results, OF2i® delivers number-based values with single-particle sensitivity. These results are statistically valid and representative of all the present particle populations.
