How can I get my raw concentration? Only getting <0.000

Hi,

it looks like your sample has a lower concentration then your lowest standard (blank)  

if you want to have „negative“ values, you have to remove the „0“ for the minimum concentration in the calibration tab

the "Min Conc." in the "Calibration" tab should be set to "<None>" for negative values. al other options in the "Min Conc" could give <x.xxx values.
