Arduino and data

I have an Arduino and a Dust sensor PPD42 connected to it.
I read the data with PLX-DAQ
In the PLX-DAQ page there is 3 columns. The first is: lowpulseoccupancy with big numbers like between 20000to 200000 The second is: ratio with numbers like 0 to 0.11 and finally a third column concentration with numbers between 0.92 and 111
All those numbers vary in proportion of the dust i have nearby the dust sensor.
I would like to know the meaning of these data. Wich column represent the ppm of dust in the air ?
Thanks for helping.
