EW-4430 Portable Blowing Agent Rapid Detector

The EW-4430 is designed based on the existing EW-4400 Portable Photoionization Gas Chromatograph. The internal structure of the instrument has been optimized. Without changing the outer shell volume, a solid sample pyrolysis furnace has been added, thereby enabling analysis of samples in different states, including gas, liquid and solid samples. The volume remains small for easy portability. In simple terms, it is a portable foam plastic blowing agent rapid detector that can detect both gas-phase blowing agents and simultaneously perform rapid detection of blowing agent components in liquid blowing agents and solid foam samples.

    Detection limit: 0.3 ppb (benzene);

    Linear range: 10⁵;

    Photoionization Detector (PID), photon energy 10.6 eV, sample ionization achieved by photons, no radioactive source;
   

    Lightweight instrument, flexible and mobile, especially suitable for on-site analysis and emergency detection of environmental pollution accidents;

    No need for hydrogen or combustion-supporting gas; high-purity nitrogen or air can be used as carrier gas, with built-in carrier gas cylinder;

    Non-destructive detection, safe and reliable;

    Analysis of organic volatiles in water, headspace sampling with direct injection detection;

    No chemical pre-treatment, concentration, enrichment or adsorption-thermal desorption required; direct injection analysis with accurate and reliable results;

    Winner of the 2005 BCEIA Gold Award.
