Purenova Mini β Portable Mass Spectrometry System

Overview

The Purenova Mini β Portable Mass Spectrometry System is a field-deployable, benchtop-sized analytical instrument engineered for rapid, on-site chemical identification without laboratory infrastructure. It integrates two foundational innovations in modern mass spectrometry: ambient paper capillary spray (PCS) ionization and single-stage vacuum miniaturization architecture. Unlike conventional benchtop or portable MS systems that rely on electrospray ionization (ESI) or atmospheric pressure chemical ionization (APCI) — both requiring purified, solvent-dissolved samples — the Mini β performs direct ionization from complex, untreated matrices (e.g., whole blood, urine, food extracts, or surface swabs) via disposable PCS cartridges. Its core mass analyzer is a linear ion trap operating under controlled pressure gradients enabled by the Discontinuous Atmospheric Pressure Interface (DAPI), a patented design that replaces multi-stage differential pumping with a single-stage vacuum chamber. This architecture reduces power consumption to ≤100 W and total system mass to 20 kg while maintaining a mass range of 50–2000 Da and MSⁿ capability up to MS³. The Mini β is not a simplified derivative but a purpose-built platform for real-time decision support in time-critical operational environments.

Key Features

• Field-Ready Form Factor: Dimensions of 55 × 24 × 31 cm (L × W × H); weight: 20 kg; operates on standard AC power or optional battery pack — no external gas supply required.
• Disposable PCS Cartridge System: Integrates sample loading, micro-extraction, and ionization into one consumable unit. Enables sub-minute analysis (<60 s per sample) with no solvent handling, derivatization, or chromatographic separation.
• DAPI-Based Vacuum Architecture: Single-stage vacuum chamber with discontinuous atmospheric interface eliminates need for high-capacity turbomolecular pumps. Sustains stable ion transmission across variable pressure zones for optimal ion fragmentation and mass analysis.
• Linear Ion Trap Analyzer: Supports full scan, product ion scan, and multiple reaction monitoring (MRM)-equivalent acquisition modes. Dynamic range >3 orders of magnitude; mass resolution ~1 amu (FWHM); scan speed >10,000 Da/s.
• Embedded Control & Cloud Integration: Onboard industrial-grade computer with touchscreen GUI; QR-code-driven method auto-loading; real-time synchronization with Purenova Chemical Cloud Analytics Platform for remote data aggregation, spectral library matching, and fleet-wide instrument management.

Sample Compatibility & Compliance

The Mini β accepts liquid, semi-solid, and surface-collected samples without pretreatment. Validated matrices include human urine, whole blood, saliva, food homogenates, environmental wipe extracts, and seized drug powders. Its PCS ionization mechanism delivers robust signal for small molecules (e.g., amphetamines, opioids, pesticides), peptides (e.g., cytochrome c), and polar metabolites — covering both volatile and non-volatile analytes. The system complies with ISO/IEC 17025:2017 general requirements for competence of testing laboratories and supports audit-ready data integrity through built-in electronic signatures, time-stamped audit trails, and encrypted local storage — meeting foundational expectations for GLP and GMP-aligned workflows. While not certified for clinical diagnostics under FDA 21 CFR Part 820 or IVD regulations, its performance aligns with ASTM E2912–22 (Standard Guide for Field Screening of Illicit Drugs Using Ambient Ionization Mass Spectrometry) and supports forensic toxicology applications consistent with SWGTOX guidelines.

Software & Data Management

The Mini β runs Purenova MassControl™ v3.x firmware, featuring intuitive workflow-guided operation: cartridge insertion triggers automatic method selection via embedded QR code, followed by autonomous solvent delivery, thermal desorption, ionization, mass scanning, and spectral deconvolution. All raw and processed data are stored locally in vendor-neutral .mzML format and synchronized in real time to the Purenova Chemical Cloud Analytics Platform. This cloud environment provides centralized spectral library hosting (including NIST-compatible libraries and custom forensic/drug panels), automated peak annotation using retention time–independent spectral matching, and role-based dashboard access for field operators, supervisors, and regulatory auditors. Audit logs record every user action, parameter change, and data export event — satisfying traceability requirements under FDA 21 CFR Part 11 for electronic records and signatures.

Applications

The Mini β is deployed where lab delay compromises outcomes:

• Law Enforcement & Forensics: On-scene identification of illicit drugs (e.g., amphetamine, methamphetamine, MDMA) in urine at LODs ≤100 ng/mL — eliminating reliance on immunoassay false positives and reducing turnaround from days to seconds.
• Food Safety Inspection: Direct screening of pesticide residues on produce surfaces or adulterants (e.g., melamine, Sudan dyes) in dairy powders without extraction or cleanup.
• Environmental Monitoring: In-field detection of VOCs and SVOCs in soil/water extracts or air particulate filters using thermal desorption–PCS coupling.
• Pharmaceutical QA/QC: Rapid verification of active pharmaceutical ingredient (API) identity and batch homogeneity during manufacturing line checks.
• Emergency Medicine: Point-of-care toxicology triage — e.g., acetaminophen overdose assessment in emergency departments using finger-prick blood spots.

FAQ

Does the Mini β require carrier gases or vacuum pump maintenance?

No. It operates exclusively on ambient air and uses a sealed, oil-free diaphragm vacuum pump with a rated service life of ≥10,000 hours. No gas cylinders, compressed air lines, or routine pump oil changes are needed.

Can the system perform quantitative analysis?

Yes. Internal standard calibration and response factor normalization are supported via MassControl™ software. Quantitative performance has been validated per ICH Q2(R2) principles for select analytes (e.g., verapamil LOD <10 ng/mL in plasma).

Is method development required for new sample types?

Minimal. The PCS cartridge’s standardized geometry and solvent delivery protocol enable rapid transfer of published methods. Most applications require only optimization of drying temperature and solvent volume — typically completed in <2 hours.

How is data security managed in cloud-connected deployments?

All communications use TLS 1.3 encryption; data at rest is AES-256 encrypted. Customers may deploy private cloud instances or air-gapped local servers compliant with GDPR, HIPAA, or CJIS requirements.

What regulatory documentation is provided with the system?

Each unit ships with a Factory Acceptance Test (FAT) report, IQ/OQ documentation templates aligned with ISO/IEC 17025, and a full set of CE-marking technical files (EMC, LVD, RoHS). Regulatory support packages for FDA submission or EU MDR alignment are available upon request.
