Dear expertise
Greetings of the day!
My query is regarding the molecular weight of the metal analyte detection using a sensor.
We usually calculate molarity to find the LOD of the sensor. So if there is a need to convert concentration units from ppm to molarity of analyte. We use formula
ppm = molecular weight x molarity x 1000
The question is, what would we need to consider the overall salt molecular weight or only metal ions weight for such studies?
Kindly help me to resolve it.
