N2 Generators Built for ELSD instruments

These nitrogen generators are matched to the precise flow and purity requirements of evaporative light scattering detection - where stable, consistent gas delivery directly impacts baseline quality and detector sensitivity. For ELSD, our integrated compressor models are the natural choice: fully self-contained, plug-and-play units that need nothing but a power outlet. No external compressor, no installation complexity - just reliable nitrogen from day one. Engineered and manufactured in Denmark for long service intervals and minimal downtime, in a footprint small enough for even the most space-constrained lab bench.

IMPORTANT to mention! If your ELSD setup demands a different nitrogen output / flowrate to ensure peak operational uptime, or you already have compressor, so you need a generator that require external air supply, then view our comprehensive selection of scalable N2 solutions for all flow requirements and air supplies.

What changes in practice

From cylinder to generator

Switching from gas cylinders to an in-house FLAIRMO generator eliminates the most common sources of ELSD variability.

No more mid-sequence interruptions

Cylinder changes introduce pressure transients. A generator runs continuously - no swaps, no spikes, no lost runs.

Consistent dryness

Our PSA process produces inherently dry nitrogen, controlled to the levels your detector requires.

Oil-free from source

Multi-stage filtration ensures that oil never reaches your nebulizer - protecting both your detector and your results.

Cylinder Supply
Pressure drop
Cylinder empties during run - pressure drift affects nebulization
Moisture risk
Regulator and connection swaps introduce ambient humidity
Logistics burden
Ordering, handling, changeover - time taken from analysis
Flairmo Generator
Constant pressure
Regulated output - stable throughout the longest analytical sequence
Dry by design
PSA separation + adsorption drying - no moisture at the detector
Zero logistics
On-demand, on-site - nitrogen available whenever analysis runs
Why gas quality defines your results

ELSD detection is unforgiving

The moment nitrogen pressure drops, moisture creeps in, or oil contaminates the nebulizer, your baseline suffers - and your results with it. Stable, dry, oil-free nitrogen is not a convenience; it is a prerequisite for reproducible detection.

FLAIRMO nitrogen generators deliver a constant, on-demand supply of clean nitrogen directly at point of use. No cylinder changes mid-sequence. No regulator creep. No pressure drop toward the end of a bottle.

What your detector actually needs

ELSD nitrogen requirements

ELSD instruments place specific demands on gas supply. Understanding these requirements is the first step to specifying a generator that performs.

01
Flow rate
0.5 – 5.0 l/min

Typical range for ELSD nebulization. Demand varies with solvent volatility - low-volatility solvents require lower flow; highly volatile solvents require higher flow to ensure complete evaporation before detection.

02
Pressure
~2 bar

Optimal nebulization occurs at approximately 2 bar at the instrument inlet. Pressure must remain constant throughout the analytical run - ripple or drift translates directly into baseline instability.

03
Purity
≥ 99.5% N₂

Minimum purity for ELSD. Equally important: the gas must be oil-free, dry, and particulate-free. Contamination at any of these points will raise background signal and compromise sensitivity.

Tailored specification

How we specify the right system for your lab

Every ELSD installation is different. We assess your detector model, method mix, operating pattern, and lab infrastructure before recommending a configuration. If you run central compressed air, we validate its suitability. If not, we integrate a compact, low-noise compressor package.

The outcome: a right-sized generator with reserve capacity, a complete air treatment chain, and a quiet footprint in your lab.

Detector & method assessment
We review your ELSD model, solvent range, and typical run patterns to establish actual flow and pressure requirements.
Infrastructure validation
If existing compressed air is available, we verify its pressure, cleanliness, and capacity before integrating it into the gas chain.
Right-sized recommendation
Model selection with reserve capacity, full air treatment chain, and acoustic footprint matched to your lab environment.
