Overview
The Peak Scientific Headspace 250 Nitrogen Generator is an engineered solution specifically designed to meet the stringent gas supply requirements of headspace sampling systems used in gas chromatography (GC) and GC–mass spectrometry (GC–MS) laboratories. Utilizing pressure swing adsorption (PSA) technology, the Headspace 250 delivers ultra-high-purity nitrogen (99.9995%) at a stable flow rate of 250 cc/min and regulated output pressure of 100 psi—optimized for both carrier gas and make-up (tail-blown) gas applications in automated headspace injectors. Unlike cylinder-based alternatives, this generator eliminates logistical constraints, safety hazards, and purity inconsistencies associated with compressed gas delivery. Its compact, stackable architecture integrates seamlessly into Peak’s Precision Series modular gas generation platform—enabling laboratories to consolidate nitrogen, hydrogen, and zero-air generation within a single footprint while maintaining independent operational control and regulatory traceability.
Key Features
- Ultra-high-purity nitrogen output (99.9995%) validated per ISO 8573-1 Class 1:2:1 for particulates, water, and oil—ensuring compatibility with sensitive GC detectors including ECD, TCD, and electron ionization (EI) sources.
- PSA-based core with dual carbon molecular sieve (CMS) beds and integrated desiccant pre-filtration—designed for continuous regeneration and long-term stability under variable load conditions.
- Modular stackable chassis (256 × 380 × 540 mm) compliant with IEC 61000-6-3 EMC standards; enables vertical integration with Peak Precision Hydrogen and Zero Air generators without inter-unit interference.
- Real-time status indicators for service intervals, filter saturation, and CMS bed health—supporting predictive maintenance scheduling aligned with GLP/GMP documentation protocols.
- Low-power operation (6.9 W typical), universal input (100–240 V AC, 50/60 Hz), and silent operation (<45 dB(A))—suitable for benchtop deployment in controlled-environment analytical labs.
- Factory-calibrated pressure regulation with built-in overpressure protection and automatic shut-down upon inlet pressure deviation (>120 psi) or system leak detection.
Sample Compatibility & Compliance
The Headspace 250 is validated for use with all major headspace autosamplers—including Agilent 7697A/7694E, Thermo Scientific TriPlus RSH, Shimadzu HS-20, and PerkinElmer TurboMatrix systems—as well as standalone GC carrier gas modules requiring inert, hydrocarbon-free nitrogen. Its output meets ASTM D6299 and USP specifications for carrier gas purity in quantitative residual solvent analysis. The generator complies with CE marking requirements (2014/30/EU EMC Directive and 2014/35/EU LVD), carries UKCA certification for post-Brexit market access, and supports 21 CFR Part 11-compliant audit trails when paired with Peak’s optional LabManager™ software suite.
Software & Data Management
While the Headspace 250 operates autonomously via front-panel controls, it interfaces with Peak LabManager™—a browser-based platform enabling remote monitoring, event logging, and electronic maintenance records. LabManager™ generates timestamped reports for gas purity verification, runtime hours, and filter replacement history—fully traceable for internal QA audits or external inspections (e.g., ISO/IEC 17025 accreditation). All data exports conform to CSV and PDF formats compatible with LIMS integration. Optional firmware updates are delivered via secure HTTPS channels with cryptographic signature validation to ensure integrity and regulatory compliance.
Applications
- Residual solvent analysis in pharmaceuticals (ICH Q3C guidelines)
- Volatile organic compound (VOC) profiling in food and beverage matrices (e.g., ethanol in wines, acetaldehyde in PET packaging)
- Environmental testing of soil/water headspace samples per EPA Method 502.2 and 8260D
- Forensic toxicology screening using static/dynamic headspace-GC–MS
- Quality control of polymer additives, adhesives, and coatings where oxygen-sensitive degradation must be avoided
FAQ
What is the recommended inlet air specification for optimal performance?
Filtered, oil-free, dried compressed air meeting ISO 8573-1 Class 2:2:2 (≤0.1 µm particles, ≤−40 °C dew point, ≤0.1 mg/m³ oil content) is required. Peak recommends pairing with a dedicated refrigerated dryer and coalescing filter.
Can the Headspace 250 be used as a carrier gas source for GC–MS systems?
Yes—its 99.9995% purity and sub-ppb hydrocarbon content satisfy the baseline stability requirements of high-resolution mass spectrometers, including triple-quadrupole and TOF platforms.
Is routine calibration required?
No scheduled calibration is needed; however, annual verification using an external electrochemical oxygen analyzer (e.g., Michell XDT-200) is recommended to confirm purity compliance per ISO 8573-1 Annex B.
How does the 12-month on-site warranty apply internationally?
Peak maintains certified service engineers across EMEA, APAC, and the Americas. Warranty coverage includes labor, parts, and travel—subject to local distributor agreements and adherence to documented preventive maintenance logs.
