hello genuine question. I'm a 3rd yr chemistry student and wanted to know the process of digestion of river water sample in step by step from collection of water sample to analyzing it in AAS machine. Hopefully this comment will be answered. Thank youuu

Then, how to calculate the background? Do we actually need to calculate them?

Thanks for the lesson 😊

could you please send me the link of the liquid accessory? My lab's FTIR is from ThermoFisher, and we only have the solid accessory.

Great explanations though buh I don’t seem to really understand

Hello Sir....can you please guide me to illustrate a result we get from AAS?? I get the absorbance value for heavy metal detection using AAS. How I can calculate the concentration of heavy metal by using this data?

It's problem lamp blink

IR is base on qualitative analysis and it's vedio uploaded on quantitative analysis 😁😛👍🏻

hello i have a question ..can we measure lead & cadmium without hydride lamp in AAS?

What will be main reason for coming negative value in balance and reagent blank

Clear message, clear structure, easy to understand, thank you

Hello excuse me, in minute 2:22 there is a pair of bars that regulates the gas flow, in my spectrometer it indicates only a interval of 0 to 10 and I need to set it on 13.5 to the oxidant, how can I do it?

Does anyone know how much the 200 AA cost? Please

Hola trabajo con.equipos de este modelo series AA pero cuando hago analisis la lampara parpadea y las lecturas son erroneas que puede provocar el parpadeo de la lampara ??

Interesante

Will there be any difference of the results if BC is either on or off?

Sir AAS 240 instrument - abs Vs con ?

What you are estimated?

Why is it neccessary to use a blank ?

Do you guys have any advise how to fix no peak detected error under 30610 code?

i have a problem in 280Z AA series , all results is good except arsenic when i checked standard apsorbance is not good how much gain i want to set

Hello. I have good experience in tuning and calibrating atomic absorption spectrometers. I'll be glad to help. my email is [email protected]

gr8 sir

nice

Hello ..how to prepare the liquid sample such as blood or urine ??

excuse me, while you were doing the quantitative analisis, may de areas of the picks were similar to each repetition (lecture)of the same sample?

so nice for explanation, but record not good!

very good explanation

Please do you have a procedure to prepare the standard solutions

Is it possible to do training in your analytical laboratory?

Tengo 2 de esos equipos en mi trabajo.. crees que puedas responder a una duda?

how to know the lifespan of the lamp (HCL)?

hello thanks a lot, I have a question, do you know where I can find to what pressure the acetylene cylinders for AAS are filled, because some say that at low pressures for safety and others that no matter high pressures someone knows if there is a regulation or specifications, I mean that pressure cylinders are filled, I am clear that the working pressure (maximum cylinder output pressure) should be about 10 psi, and that the tank pressure should not be less than 100 psi per training of acetone that breaks down the packaging, but I can buy 2,000 psi cylinder if I have the regulator or I have to buy 300 psi, thank you very much,

I adjust and calibrate the device. I have a lot of experience in spectrometry. I can help.

Thank you very much. You have the nicest, calm, understandable speaking voice of any scientist that I have herd on KZbin for laboratory instrument instructional videos. You can watch my science/geology videos on KZbin by typing in Frank Reiser M.S.

really beautiful work

and do u have protocol for that?

hi! how long can we store the solution in plastic bottles? thanks

"the flame is gonna be lit" heh ;-)
