💡 Application Scenario: Evaporative Light Scattering Detector (ELSD)
In laboratories, nitrogen generators serve Evaporative Light Scattering Detectors (ELSD) by providing a stable, clean, and dry nitrogen supply. Their functions can be summarized in the following aspects:
1️⃣ Nebulization and Carrier Gas
▶ The working principle of an ELSD involves first nebulizing the liquid-phase effluent into fine droplets, then evaporating the mobile phase at high temperature, leaving non-volatile analyte particles, which are subsequently detected via light scattering.
▶ This nebulization process requires a high-purity, stable gas source (typically nitrogen) to generate the airflow that propels and atomizes the sample.
2️⃣ Accelerating Solvent Evaporation
▶ The dry nature of nitrogen helps rapidly remove the mobile phase solvent in the evaporation chamber, improving evaporation efficiency and reducing background noise.
3️⃣ Reducing Oxidation and Contamination
▶ ELSD is often used to detect non-volatile or thermally unstable compounds. Using nitrogen (an inert gas) prevents oxidation reactions caused by oxygen in the air and minimizes interference from moisture during detection.
4️⃣ Lowering Operating Costs
▶ Replacing high-pressure nitrogen cylinders with a nitrogen generator enables continuous supply of high-purity nitrogen, eliminating the need for frequent cylinder changes, enhancing safety, and reducing long-term expenses.
▶ Full Compatibility: Adjustable pressure range from 0–8 bar, compatible with ELSDs from leading brands such as Agilent, Waters, and Shimadzu.
💡 Application Scenario: Sulfur Dioxide Analyzer
In sulfur dioxide analyzers (especially UV fluorescence SO₂ analyzers or chemiluminescence methods), laboratory nitrogen generators play a key role in the following aspects:
1️⃣ Providing Zero Gas
▶ During SO₂ measurement, a gas free of SO₂, moisture, and particulates is required as a baseline reference (zero gas) for calibration and to eliminate background signals.
▶ High-purity nitrogen serves as an ideal zero gas source due to its inert nature and absence of SO₂ and other interfering gases.
2️⃣ Carrier or Dilution Gas
▶ In certain analytical methods (e.g., gas chromatography for SO₂ analysis), nitrogen can be used as a carrier gas to transport the sample gas through the separation and detection system.
▶ During calibration, nitrogen can also be used to dilute the SO₂ in standard gas to the desired concentration.
3️⃣ Protecting Optical and Sensing Components
▶ The dry and inert properties of nitrogen help prevent moisture or corrosive gases from damaging sensitive components such as UV optical systems and photomultiplier tubes.
4️⃣ Replacing Gas Cylinders to Reduce Costs and Risks
▶ Nitrogen generators provide a continuous supply of high-purity nitrogen, eliminating the need for frequent replacement of high-pressure cylinders, thereby enhancing safety and reducing operational costs.
