Hello AGILENT family,
i have a few questions on the analysis of Pb in blood samples.
am failing to get the right concentrations of the QC sample 8ppb instead it’s reading 0.08 ppb and at the same time it’s also showing overange (0.08o) even when my highest standard is 25 ppb.
i can’t really get the right concentration, I don’t understand where am going wrong
kindly advise if anyone has come across this.
Am using an AGILENT MP-AES 4210 instrument.
digesting samples in 30% HNO3 & 30% H2O2 using a microwave digestion.
attached are the pics
