Answer / devendra kumar
ppb means parts per billion.
mass of solute/mass of solution*10000000=ppb
ppm means parts per million.
mass of solute/mass of solution*1000000=ppm

Answer / vipul patel
PPM is a term used in chemistry to denote a very, very low
concentration of a solution. One gram in 1000 ml is 1000
ppm and one thousandth of a gram (0.001g) in 1000 ml is one
ppm.
dilute 1ml of 1ppm solution to 1000ml is 1ppb

I have compare C2H2-air and C2H2-N2O flame AAS on determination calcium. Both use same range of std to plot calibration curve. (2-6ppm) When i measure the sample with phosphate, KCl and LaCl, C2H2-N2O flame give false positive result, around 0.5ppm. When i measure the sample with phosphste, KCl and EDTA. C2H2-N2O flame also give 0.5ppm false positive. But both above mentioned sample would not give false positive when measured by C2H2-air flame. What is the reason?
