Overview
SweebIR is a full-featured FTIR spectrometer with a built-in diamond ATR, offering lab-grade quality at a price that makes it affordable for a wide range of applications. The FIDES*Core software and a ready-to-use tablet are included: simply unpack, switch on and measure. Even without any spectroscopy experience, you will record reliable IR spectra from day one.
Compact
With a footprint of 30 × 30 cm and a weight of 7.5 kg, it fits on any lab bench and is easy to move.
Diamond ATR included
The diamond ATR unit is an integral part of SweebIR. This guarantees optimal alignment of the diamond and eliminates the cost of a modular solution and of sealing the housing – you don't pay extra for the ATR unit. A simple, clean solution for everyone who does not need transmission measurements. It also makes the usual CO₂ correction obsolete.
Self-aligning
The patent-pending interferometer unit aligns itself and therefore always delivers the best results. Scan speed and resolution are optimally set at the factory, but can be adjusted at any time.
Detector
Our patented detector with a LiTaO₃ crystal is among the most broadband, fastest, most sensitive and lowest-noise detectors of its kind worldwide – which is exactly why it is built into every SweebIR.
Tablet and FIDES platform included
Every SweebIR ships with a tablet with the FIDES*Core app pre-installed, so you can start measuring spectra right away. All spectra and, depending on the software module, analyses and reports are then available on the FIDES analysis platform, where you can access and manage them in the browser from any PC with internet access and, of course, export them as CSV if needed. Talk to us about your automated processing workflows and the corresponding API access.
Personal support, direct from the manufacturer
SweebIR is developed and built in Hamburg, Germany – from the detector and the interferometer to the software. You always have a personal contact, and support comes directly from the people who developed your instrument. For you, that means fast help, solutions for your requirements and an open ear for your ideas.
Applications
FTIR spectroscopy is one of the most versatile analytical methods in the lab. With SweebIR and its diamond ATR, you can measure solids, powders, liquids, pastes and films without sample preparation – for identity testing, quality control and materials analysis across many industries.
Pharma QC & pharmacy
Identity testing of active ingredients, excipients and starting materials according to Ph. Eur. 2.2.24 and USP – fast and reliable in incoming goods inspection, raw material testing and quality control (QC). Ideal for the pharmaceutical industry, contract manufacturers and pharmacies.
Chemicals & industry
Molecular spectroscopy for routine analysis: identification of organic and inorganic substances, purity control of solvents and chemicals, testing of raw materials and intermediates, as well as contaminant and complaint analysis.
Plastics & polymers
Polymer identification by ATR in seconds: films, granules, fibres, coatings, adhesives and rubber. For incoming inspection, mix-up checks, failure analysis, recycling and plastic sorting (e.g. PE, PP, PET, PVC, PA).
Food & cosmetics
Fast testing of fats, oils, sugars, flavourings and additives: verify identity and authenticity and detect adulteration (food fraud). Also suitable for raw materials in cosmetics, dietary supplements and natural products such as essential oils.
Cannabis & CBD
Determination of THC and CBD content in cannabis flowers and extracts – fully automated with FIDES*Canna according to Ph. Eur. 5.21. For medical cannabis, pharmacies, manufacturers and laboratories – fast and without time-consuming sample preparation.
Teaching & research
The compact FTIR spectrometer for universities, colleges, schools and vocational training: IR spectroscopy in lab courses, teaching and the research lab – robust, portable and easy to operate via tablet, even for students with no prior knowledge.

* The built-in diamond ATR has a significant influence on the signal-to-noise ratio and spectral range. These values are therefore not comparable to the usual specifications of other FTIR instruments, which are determined in transmission.
Software
Want it even easier? Then add one of our software packages: identity testing for the pharmaceutical industry, cannabis analysis for THC and CBD content, or fully automated content analysis. Do you have a special analytical task? Get in touch – we will be happy to develop a suitable solution for you.
FIDES*Core
Basic package · always included€0
With our modern FIDES*Core app, you can easily record IR spectra on the supplied (Android) tablet and manage them in your own database – with minimal effort and intuitive operation.
All data is also available in your online account at sweeb.wiredsense.com, where it can be analysed or downloaded to any computer with internet access. Immediately after each measurement, your data is available there in an audit-proof form.
For customers who, for security reasons, prefer not to store data online, we also offer PC software (Windows, Linux, Mac) that lets you work with the instrument completely offline.
FIDES*Pharm
Add-on packageFor identity testing according to Ph. Eur. 2.2.24, we offer automatic spectral comparison against our own reference database. It mainly comprises IR spectra of EDQM CRS substances and was recorded in-house under strict GLP rules.
FIDES*Canna
Add-on packageSince 2025, we have offered fully automated cannabis analysis of THC and CBD content. To develop it, we examined both flowers and MCT-based extracts and built a model according to Ph. Eur. 5.21 – so medical cannabis can be tested to the high standards of the pharmacopoeia.
FIDES*Mix
Add-on packageFTIR spectroscopy is excellent for quantitative analysis. To make your work easier, we offer automatic content analysis for various mixtures – and find solutions for special cases, too. Contact us to find out whether FIDES*Mix can determine the content of your target substance in your mixture.
Basic package FIDES*Core: €0 – included. First add-on package €39/month, each additional one only €19/month.
Frequently asked questions
What happens if I cancel?
You can cancel the add-on package subscriptions on a monthly basis. After that, you will not incur any further costs. FIDES*Core is free of charge anyway and therefore cannot be cancelled.
Is there a minimum term for subscriptions?
No.
Can I add packages at any time?
Yes, billing is calculated to the exact day.
