Precision Series

Manufacturer – Peak Scientific

Description:Precision Series provides compact, modular on-site nitrogen generation tailored for GC detector make-up, carrier and headspace applications—eliminating cylinder dependencies. It combines ultra-high purity output with flexible footprint and modular stacking to adapt as your lab evolves.

Technical specifications:
Max purity: up to 99.9995% nitrogen.
Output flow rates: e.g., 250 cc/min (Precision Nitrogen 250), 600 cc/min (Precision Nitrogen 600), 1000 cc/min (Precision Nitrogen 1000)
Maximum output pressure: typically, around 80 psi / ~5.5 bar (models 250/600/1000)
Start-up time: approx. 90 minutes to reach operating purity.
Technology: Uses Pressure Swing Adsorption (PSA) and Carbon Molecular Sieve to remove oxygen and moisture; some “Trace” models also include catalytic oxidation to reduce hydrocarbons to < 0.05 ppm.
Key features:
• On-demand nitrogen generation ensures continuous, stable supply and avoids downtime from cylinder change-overs.
• Ultra-high purity (up to 99.9995%) suitable for sensitive GC applications requiring minimal contaminants.
• Modular, stackable design — compact footprint and ability to expand capacity or integrate with other gas modules (e.g., hydrogen, zero air) as lab demands grow.
• Minimal maintenance: typically, annual filter change, no cylinder handling, and rapid start-up.
• Dedicated compressor module option when no house compressed air supply available.
Applications: Ideal for GC and GC-MS systems, headspace vial pressurization, purge & trap, tube conditioning for thermal desorption, and sample preparation workflows in analytical labs.

Sub-model names:
• Precision Nitrogen 250 – up to ~250 cc/min flow, standard purity (~99.9995%) for detector make-up gas.
• Precision Nitrogen 600 – up to ~600 cc/min flow, standard make-up gas for GC/GC-MS.
• Precision Nitrogen 1000 – up to ~1000 cc/min flow, for higher throughput or multi-instrument GC setups.
• Precision Nitrogen Trace 250 – ultra-high purity model (~99.9995%+, hydrocarbon <0.05ppm), up to ~250 cc/min flow.
• Precision Nitrogen Trace 600 – ultra-high purity (~99.9995%+), up to ~600 cc/min, for carrier/make-up/reference gas at trace detection levels.
• Precision Nitrogen Headspace 250 – tailored for headspace sampler instruments needing higher pressure (~100 psi) at ~250 cc/min flow.
