Gravity: Formaldehyde (HCHO) Sensor

Hi,
I'm looking for a sensor only for Formaldehyde.
This sensor is capable to recognize only the HCHO ppm or measures indistinctly also other substances as alcohol, benzene, toluene...
Do yo have also the library to download for Arduino and also the code?
Thanks.
