hi
i m studing AAS(atomic absorption specvtroscopy) technique.using beer"s law i plot a graph bw absorbance and concentration.then how can i make the quantitative analysis of my sample?

compare it to known quantities

Hi, that's great that you are studying AAS. The first step in making a quantitative analysis of your sample is to ensure that your graph follows Beer's law, which states that the absorbance of a substance is directly proportional to its concentration. Once you have established a linear relationship between absorbance and concentration, you can use this graph to determine the concentration of your sample. This can be done by measuring the absorbance of your sample and then using the graph to find the corresponding concentration value. It is important to note that this method assumes that there are no interfering substances present in your sample. If there are, you may need to use a different technique or adjust your results accordingly. Additionally, it is important to use standard samples with known concentrations to create your calibration curve and ensure accurate results. I hope this helps and good luck with your analysis!
