BME 680 b- VOC detection from the gas sensor resistance

[Mahendra_ms]

Hey.. there 
First of all, I would like to say thanks to Bosch Sensortech for such a great innovation like BME 680!

We're developing one product with BME 680 

The intend is to monitor the VoC compounds from the human breath
 As per the datasheet of the BME 680(page 9 / Table 5), the sensor is sensitive to b-voc  which includes Ethane, Carbon Monoxide, Action, Ethanol, and Isoprene /2-methyl-1,3 Butadiene

I'm using BSEC library from where I'm getting the gas sensing resistance too 
Now can anyone tell me, is there any way to get b-VoC compounds from the same 

I would appreciate all comments and suggestions
 
Thanks with Gratitude!

Since you are already using BSEC lib, the lib will output one b-voc estimate value directly which you can directly use. 

But BME680 is not able to distigruish which kind of b-voc compound from the read out value,  only can tell you the overall gas concetration increasd or decreased.
