Very Good! But the student made an error while explaining the absorption of the lamp's light. That was actually the emission not the Absorption.
Nice video, However the atoms of intrest in the flame will absorb light from the hollow cathode tube, this will decrease the amout of light going to the photo multiplier. The decrease in light detection reguarding the sample compared to the amount of light detected with just the hollow cathode tube is converted to a measurable amount of absorption.
Oh thank you so much. I was having a hard time visualising it and my textbook wasn't helping much
That was one nice tutorial for AAS.. Thanks Katherine..
12 years later and it's still educative. Thanks alot

This video is nothing less than a treasure for the students coming from the third-world countries who can just dream of having this type of sophisticated equipment in their labs. Unfortunately, this equipment is costly and requires a lot of funding from the government and scientific societies. However, it is the sole responsibility of their governments to provide them such advanced equipment to enrich them with the practical aspect of doing a degree in chemistry. Without practicality, what's the use of having immense theoretical knowledge of how these machines work? They think and believe developed-nation students are living in heaven and having all the means to become competent chemists and analysts in life. Thank God , this type of video at least provides us an opportunity to see them from afar without even touching them. Alas, this is the inner voice of a student studying chemistry at one of the general public universities in his country and still hoping for the best future. Is it not an irony? By the way, thank you so much for a helpful and blissful video.
