+ 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:

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; analyzing 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.

Send us your sample(s) – and we’ll do the rest

Find out whether OF2i® or OF2i®+Raman analysis is the answer to your particle challenges!
Get in touch, we’ll organize measurements on your sample(s) and send you a detailed measurement report. This is the first (non-binding) step to a feasibility study. Open the door to deeper insights today!

PAT sensor for 24/7 monitoring of production

The OF2i® principle will soon be available as a PAT solution for continuous online monitoring of (nano)particles during production. The BRAVE B-Continuous PAT sensor, which launches in 2024, runs 24/7 and lays the foundation for RTRT (Real-Time Release Testing).

BRAVE B-Continuous opens the door to:

Why OF2i®?


Uses induced motion as a revolutionary measurement principle.


Measures up to 3000 particles per minute 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 2500 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.
