Can anyone help in finding out LDL for atomic absorption spectroscopy?
As a rule of thumb, multiply the standard deviation of several blank absorbance values (minimum 10) by the factor three (based on the three-sigma rule) and use your sensitivity (i.e. the slope of your calibration curve) to convert that absorbance value to concentration.
Another approach is to calculate it from the residual variance of your calibration curve, like in DIN 32645.
