Agiltron PeakSeeker Pro Desktop Raman Spectrometer

Overview

The Agiltron PeakSeeker Pro Desktop Raman Spectrometer is a compact, benchtop-integrated system engineered for reliable, laboratory-grade Raman spectroscopy without the complexity or cost of high-end modular platforms. Based on dispersive optics and a thermoelectrically stabilized 785 nm diode laser excitation source, the instrument operates on the fundamental principle of inelastic light scattering—where incident photons interact with molecular vibrational modes to generate characteristic Stokes and anti-Stokes shifts. These spectral fingerprints enable non-destructive, label-free identification and quantification of chemical species across pharmaceuticals, polymers, forensics, materials science, and academic research. Designed for operational continuity in regulated and non-regulated environments alike, the PeakSeeker Pro delivers consistent performance within a robust aluminum chassis, supporting both routine screening and exploratory feasibility studies under ambient lab conditions.

Key Features

• Stable 785 nm excitation: Minimizes fluorescence interference while maintaining sufficient photon flux for sensitive detection across organic and inorganic matrices.
• High-quantum-efficiency CCD detector: Frame-based integration architecture reduces cooling requirements without compromising signal-to-noise ratio across the 200–3000 cm⁻¹ range.
• Optimized optical throughput: f/2.2 imaging spectrometer with NA = 0.22 ensures efficient light collection from micro-scale sample areas (0.1–0.3 mm spot size).
• Benchtop ergonomics: Compact footprint (36 × 29 × 11 cm) and sub-3.6 kg mass facilitate placement on standard lab benches, fume hoods, or shared instrumentation carts.
• Integrated thermal management: Passive and active stabilization maintains wavelength accuracy (<1 cm⁻¹ drift over 12 h) and photometric repeatability (<4% intensity variation over same period).
• Laser line rejection: Hard-coated, high-optical-density notch filters suppress Rayleigh scatter to OD >6, enabling clean isolation of Raman bands near the laser line.

Sample Compatibility & Compliance

The PeakSeeker Pro accommodates diverse physical states—including solids, powders, gels, and liquids—without requiring extensive sample preparation. Measurements can be performed through transparent packaging (e.g., glass vials, plastic bags, blister packs), supporting non-invasive quality control and counterfeit screening. Optional accessories extend functionality: the RSM Microscope enables confocal micro-Raman analysis; the MSK Microscopy Kit provides standardized coupling to OEM upright or inverted microscopes. For regulated workflows, the system supports 21 CFR Part 11 compliance via RSIQ-CFR software, delivering audit-trail logging, electronic signature enforcement, role-based access control, and data integrity safeguards aligned with GLP and GMP documentation standards.

Software & Data Management

Each system ships with a preconfigured laptop running RSIQ—the core acquisition and processing suite. RSIQ provides real-time spectral preview, baseline correction, peak fitting, and library search capabilities. Two licensed add-ons are available: RSIQ-QUAL performs automated unknown identification by comparing acquired spectra against commercial reference libraries containing >5,000 compounds; users may curate proprietary libraries for internal standards. RSIQ-QUANT implements multivariate calibration models (PLS, PCR) for quantitative analysis of mixtures, including concentration prediction and batch consistency monitoring. All software modules store metadata (instrument parameters, operator ID, timestamp, environmental logs) in encrypted SQLite databases, ensuring traceability and long-term archival compatibility.

Applications

• Pharmaceutical raw material verification and excipient characterization per USP and ICH Q5C guidelines.
• Polymorph screening and crystallinity assessment in API development.
• Forensic analysis of illicit drugs, explosives, and pigments—validated against ASTM E2598 and ISO/IEC 17025 protocols.
• In-process monitoring of polymerization reactions and catalyst behavior.
• Academic teaching labs: demonstration of vibrational selection rules, resonance effects, and symmetry-based band assignment.
• Quality assurance in food safety (e.g., adulterant detection in oils, dairy, and spices) and cosmetics (preservative profiling, fragrance verification).

FAQ

Is the PeakSeeker Pro suitable for regulatory submissions?
Yes—when configured with RSIQ-CFR and operated under documented SOPs, the system meets data integrity requirements for FDA, EMA, and PMDA submissions, including electronic records and signatures per 21 CFR Part 11.

Can it analyze samples inside sealed containers?
Yes—its 785 nm excitation and optimized optical path allow high-fidelity measurement through glass, PET, polyethylene, and other common transparent packaging materials.

What maintenance is required?
No routine optical alignment is needed. The system undergoes factory calibration traceable to NIST standards; annual verification using certified polystyrene or silicon reference samples is recommended.

Does it support external triggering or synchronization?
Yes—TTL-compatible trigger input/output ports enable hardware synchronization with stages, pumps, or process controllers for time-resolved or spatially resolved experiments.

Is remote operation supported?
Yes—RSIQ includes secure remote desktop capability and RESTful API endpoints for integration into LIMS or MES platforms via HTTPS.
