What does NGA mean?

NGA stands for NitroGen + AirGen. These units generate both nitrogen and dry instrument air simultaneously from a single compressor and membrane system — eliminating the need for a separate compressed air source or standalone air dryer. Each NGA model is pre-configured for a specific instrument platform with factory-set pressure regulators and flow rates matching OEM requirements.

The 3G designation means three simultaneous gas outlets from one unit: Curtain Gas (high-purity N₂), Gas 1 / Gas 2 (dry instrument air for source and sheath), and Exhaust (regulated compressed air). All three independently pressure-regulated. No electrical components — purely pneumatic operation with zero noise.

Technology

Why choose NG Series

⚗️

PSA Technology

Pressure Swing Adsorption separates nitrogen from air using molecular sieves. Delivers ultra-high purity nitrogen continuously without liquid nitrogen or cylinders.

🔄

Membrane Technology

Hollow fiber membrane modules separate nitrogen from compressed air. Low maintenance, no moving parts — ideal for high-volume industrial and central lab supply.

🔌

Integrated Compressor

XS iQ and XL iQ models include built-in scroll compressors — no compressed air infrastructure required. Truly plug-and-play installation.

🎯

LC-MS Grade Purity

Purpose-built for demanding LC-MS applications. Meets OEM specifications for Agilent, Waters, Sciex, Shimadzu, and Thermo Fisher instruments.

📱

Smart Controls

Touchscreen LCD, RS-485, and RS-232 standard. Real-time purity monitoring, flow control, and remote alarm capability. Optional WiFi on select models.

♻️

Eliminate Cylinders

End cylinder rentals, deliveries, and handling risks. Continuous on-demand generation ensures uninterrupted supply at a fraction of the cylinder cost.

Applications

Proven performance across
analytical methods

From routine LC-MS to high-throughput ICP-MS, NG Series generators supply reliable high-purity nitrogen for the widest range of laboratory applications.

LC-MS / LC-MS/MS

Nebulizer gas, curtain gas, and drying gas for liquid chromatography-mass spectrometry. Meets OEM purity specifications.

GC-FID / GC-NPD

Make-up gas and detector gas for gas chromatography. Ultra-low hydrocarbon content ensures detector baseline stability.

ICP-MS Collision Cell

UHP collision cell gas supply via optional 99.9999% outlet on XL iQ models. Removes polyatomic interferences reliably.

FTIR Purge Gas

Moisture-free nitrogen purge for FTIR optics and sample compartments. Eliminates CO₂ and water vapor interference.

Sample Evaporation

High-flow nitrogen blowdown for solvent evaporation in sample preparation workflows. Turbo Vap and similar systems.

ELSD Detection

Nebulizer gas for Evaporative Light Scattering Detection in LC. Consistent purity critical for detector sensitivity.

Incubators & Storage

Inert atmosphere generation for cell culture incubators, dry storage cabinets, and sensitive sample preservation.

Agilent MP-AES

Dedicated NGA CASTORE MP-AES model supplies both the high-flow N₂ and dry instrument air required for Agilent's Microwave Plasma Atomic Emission Spectrometers.

3D Laser Printing (SLS/SLM)

CASTORE XL iQ 3D Printing model purges oxygen from build chambers to prevent material oxidation during laser sintering and melting processes. Programmable purge algorithm included.

Central Lab Supply

CASTORE BASIC and PRO models serve as central nitrogen supply points for entire laboratory facilities via distribution manifolds.
