High Performance Liquid Chromatography (HPLC)
Formaldehyde was low molecular weigh poison gas in ambient air, cause eye and respiratory tract irritation and skin sensitization. Refer analysis method of USEPA Method TO-11A determination of Formaldehyde in Ambient air using adsorbent Cartridge followed by High Performance Liquid Chromatography (HPLC). This method was active sampling by suction the air into DNPH adsorbent cartridge, the reacting airborne carbonyl with 2,4-dinitrophenylhydrazine (2,4-DNPH) coated on an adsorbent cartridge followed by separation and analysis of the hydrazone derivative by high performance liquid chromatography (HPLC) with ultraviolet (UV) detection.
HPLC (DNPH cartridge)
The DNPH cartridge was accurate and precisely sampling 100-2,000 mL/min of ambient air. Formaldehyde and Acetaldehyde concentration 0.01 µg/cartridge

Sampling and tested by HPLC
ALS provided the active sampling on site for the environment, workplace to quantitate atmospheric concentrations of Formaldehyde and Acetaldehyde. Or the passive sampling for personal sampling by industrial hygienist to assess the efforts of respiratory exposure for Formaldehyde and Acetaldehyde on worker.
