The paper below from the Institut fur Chemie in Germany compares GC- PID, FID and ECD for non urban samples that were concentrated on tenax. The PID (Model PI52) with an HNU 11.7 eV lamp compares in sensitivity with the ECD for low MW chloroalkanes. and with the FID for a number of hydrocarbons. The HNU PID with a 10.2 eV lamp is more sensitive than the FID or the PID with an 11.7 eV lamp.
