Micro GPN-500 Nitrogen Generator: High-Purity, Reliable Gas Source
for Laboratory Instruments
Introduction
The Micro GPN-500 Nitrogen Generator is a cutting-edge solution
designed by our Gas Source Department to deliver a consistent,
high-purity nitrogen supply for critical laboratory instruments.
Engineered to replace traditional high-pressure steel cylinders,
this generator caters to the needs of gas chromatographs (GC),
Fourier transform infrared spectrometers (FT-IR), total organic
carbon analyzers (TOC), nuclear magnetic resonance (NMR) systems,
and thermal analyzers. With a flow rate of 500ml/min and nitrogen
purity exceeding 99.99%, the GPN-500 ensures uninterrupted
operation, cost efficiency, and enhanced safety, making it an
indispensable tool for modern laboratories.
Key Features & Advantages
1. Cylinder-Free Convenience & Safety
The GPN-500 eliminates the hazards and logistical challenges of
high-pressure steel cylinders. Its dual-cathode stainless steel
electrolytic separation cell enables on-demand nitrogen production,
starting instantly upon power-up. This design not only reduces the
risk of gas leaks or cylinder explosions but also eliminates the
need for manual cylinder replacements, saving time and labor costs
for laboratory staff.
2. Low Maintenance & Cost Efficiency
Operating the GPN-500 is remarkably straightforward: during normal
use, it requires only periodic addition of pure water (resistivity
≥1MΩ/cm) to sustain continuous nitrogen generation. This eliminates
the recurring expenses associated with cylinder refills, making it
a cost-effective long-term investment. The generator's durable
construction minimizes wear and tear, further lowering maintenance
costs over its lifespan.
3. Superior Purity & Reliability
Equipped with a unique anti-backflow device, the GPN-500 prevents
reverse gas flow, safeguarding both the generator and connected
instruments from contamination. Its three-stage purification system
ensures nitrogen purity exceeds 99.99%, meeting the strict
requirements of sensitive analytical techniques like NMR and GC.
Additionally, the disposable stretched-mold purification tube
reduces potential leakage points, enhancing overall system
reliability and extending service life.
4. Uninterrupted Operation
A large 3-liter water storage tank allows the GPN-500 to run
continuously for days on a single water fill, ideal for unattended
or extended experiments. This feature is particularly valuable for
laboratories with high-throughput workflows, ensuring instruments
receive a steady nitrogen supply without interruptions.
