Anton Paar Cora 100 Portable Handheld Raman Spectrometer

Overview

The Anton Paar Cora 100 is a fully integrated, battery-powered handheld Raman spectrometer engineered for rapid, non-destructive molecular identification in field and industrial environments. Based on 785 nm laser excitation and optimized optical path design, it delivers high-fidelity Raman spectra across a broad fingerprint region (400–2300 cm⁻¹), enabling unambiguous chemical characterization of solids, liquids, and powders without sample preparation. Its compact form factor—measuring only 15.8 × 10.1 × 2.9 cm and weighing 650 g—is purpose-built for single-hand operation, real-time decision-making, and deployment in regulated or hazardous locations where benchtop instrumentation is impractical. The system complies with MIL-STD-810G for shock, vibration, and thermal cycling, and achieves IP67 ingress protection, ensuring operational reliability under extreme ambient conditions (−20 °C to +40 °C).

Key Features

• Robust mechanical architecture validated to MIL-STD-810G for drop, shock, and environmental stress testing
• IP67-rated enclosure providing full dust-tightness and immersion resistance up to 1 m for 30 minutes
• High-sensitivity linear CCD detector coupled with thermally stabilized 785 nm diode laser (>215 mW at sample surface)
• Spectral resolution better than 10 cm⁻¹ across the entire 400–2300 cm⁻¹ range, supporting precise peak discrimination
• Sub-millimeter spatial resolution enabling targeted analysis of heterogeneous samples or small features
• Embedded Linux operating system with intuitive touch-enabled GUI in multiple languages including English and Chinese
• On-device spectral acquisition, baseline correction, and library matching—no external PC required for routine screening
• Rechargeable lithium-ion battery supporting up to 60 consecutive Raman acquisitions per charge (typical usage)

Sample Compatibility & Compliance

The Cora 100 supports direct analysis of raw, unprocessed materials—including pharmaceuticals, polymers, explosives precursors, illicit substances, lubricants, and battery electrolytes—through transparent packaging (e.g., plastic bags, glass vials). Its contact-based measurement mode ensures consistent probe-to-sample coupling, while optional accessories—including an auto-focus adapter, 90° right-angle probe, and sample bottle holder—extend versatility across irregular geometries and containment formats. The instrument meets requirements for field-deployable analytical tools under ISO/IEC 17025-accredited laboratories when used with documented calibration protocols. While not inherently 21 CFR Part 11 compliant due to its embedded-only workflow, audit-ready data export (text-based .txt spectra with timestamps and metadata) facilitates integration into LIMS or ELN systems supporting GxP workflows.

Software & Data Management

Pre-installed firmware includes spectral acquisition control, real-time background subtraction, and on-device chemometric matching against user-configurable spectral libraries. All acquired spectra are timestamped and stored locally in plain-text format compatible with third-party analysis platforms (e.g., MATLAB, Python SciPy, GRAMS/AI). USB 2.0 connectivity enables bulk data transfer and firmware updates. No proprietary binary formats are used; raw intensity vs. wavenumber data is fully accessible and interoperable. Optional software packages support advanced multivariate analysis (PCA, PLS-DA), spectral alignment, and library expansion with reference standards traceable to NIST SRMs.

Applications

• Rapid verification of incoming raw materials in pharmaceutical, chemical, and food manufacturing (per USP & EP monographs)
• Field-based detection of counterfeit or adulterated medicines and consumer products
• First-responder screening for hazardous or explosive compounds in customs, border control, and emergency response
• In-line quality assurance during polymer compounding or battery electrode coating processes
• Non-invasive forensic analysis of trace evidence (e.g., pigments, fibers, illicit drug residues)
• Academic and industrial research requiring mobile Raman capability for in situ or outdoor measurements

FAQ

Is the Cora 100 suitable for quantitative analysis?
The Cora 100 is primarily designed for qualitative identification and semi-quantitative screening. Quantitative accuracy depends on calibration using matrix-matched standards and is subject to laser power stability and sample homogeneity.
Can the battery be replaced by the user?
No—the lithium-ion battery is sealed and not user-replaceable. Service-level replacement requires authorized Anton Paar technical support.
Does the instrument require annual recalibration?
While no scheduled recalibration is mandatory, Anton Paar recommends periodic performance verification using the included polystyrene standard (Raman shift at 1003 cm⁻¹) to confirm spectral axis accuracy and resolution consistency.
What spectral libraries are preloaded?
The device ships with a core library of >1,200 reference spectra covering common pharmaceutical actives, excipients, polymers, and hazardous chemicals. Users may import additional libraries in standard JCAMP-DX or plain-text format.
Is remote data synchronization supported?
Native cloud sync is not implemented; however, exported .txt files can be integrated into enterprise data management platforms via scripted ingestion workflows or middleware APIs.
