Tip:
Providing a nitrogen source for CAD (Charged Aerosol Detector) requires high-purity, dry, oil-free nitrogen gas, which is crucial for the performance and stability of the detector
Recommended gas source solution
Option 1: High purity nitrogen gas cylinder (suitable for small and medium-sized laboratories)
-Configuration:
-Cylinder purity: 99.999% high-purity nitrogen
-Two stage pressure reducing valve (imported brands such as Swagelok and Parker)
-Stainless steel/copper pipe (polished inner wall)
-Terminal filter (0.01 μ m particle removal+activated carbon hydrocarbon removal)
-Advantages: Ready to use, guaranteed purity
-Disadvantage: Regular replacement of steel cylinders is required, resulting in high long-term costs
Option 2: Nitrogen generator (recommended for long-term use)
-Type selection:
-PSA (Pressure Swing Adsorption) generator: purity 99.5%~99.9%, flow rate 5-10 L/min
-Membrane separation generator: purity of 99%, low flow rate (suitable for single machine)
-High purity type (PSA+catalytic deoxygenation): purity 99.999%, flow rate>2 L/min (such as Peak Scientific, Parker Balston)
-Key parameters:
-Output pressure: adjustable from 0 to 150 psi
-Dew point: below -70 ° C
-Built in particle filter (0.01 μ m)
-Advantages: No need to replace the steel cylinder, continuous gas supply, lower cost
-Attention: Regularly replace the filter element and desiccant (every 6-12 months)
Maintenance Recommendations
-Daily: Record the inlet pressure value
-Monthly: Calibrate actual flow rate with soap film flowmeter
-Quarterly: Replace terminal filters and detect dew points
-Annual: Conduct in-depth maintenance on the generator (replace filter element, maintain air compressor)
The sensitivity of CAD detector depends half on chromatographic separation and half on the quality of nitrogen gas.
