Ppb-level formaldehyde sensor utilizing a compact 3D-printed differential photoacoustic cell and a 320 nm UV laser

Precise measurement of formaldehyde (H2CO) is a vital defense line for health, crucial for risk warning and prevention of major diseases like leukemia and cancer. The cross-interference of commercial electrochemical and metal oxide semiconductor sensors is grievous for H2CO sensing. Spraying disinfe...
