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
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,
The pressure on the tank when full is your gas provider responsibility. Your job is to set up your regulator to between 9.5-14.5 psi (depending on your samples). Bellow 9.5 your flame will blow out easily and above 14.5 you are risking an explosion. Acetylene is packed in Acetone and when you run the tank bellow 100 psi acetone will enter your gas box (which you should never touch) and also your spray chamber and will damage your O-rings, they dissolve quickly into a black mass that you will have to clean up.
I do too, what kind of parameter in your calibration standards do you have for let's say copper. I have a 10ppm and 30ppm STD and after calibration using g a mean absrobance of .4700-.5000 for 30ppm and .1700-.1800 for 10 ppm, we run samples reading the STD between every 20 samples, our standard for 30, ppm will vary from 29.5 to 30.3 and we are trying to narrow this range in absorbance. Do you have any tips?
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 ??
@@paelams claro que si funciona pero en algunos casos funciona mejor con unos elementos que con otros. Si tu contactas a un Product Specialist de Agilent el te puede decir si tus samples se pueden corren juntos o no. Yo soy technico de servicio. Reparo las máquinas pero no las corro.
@@chaleco82 Hola, disculpa me podrias ayudar? lo que pasa es que en la escala de flujo de aire solo me aparece del 0-10 y necesito calibrarlo a 13.5 pero no me deja
Thanks for the lesson 😊
Thank you sir. It's helpful.

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

You have to get a regulator, to use the indicated flow rate for your specific instrument

To late, he blowed the whole lab.
I adjust and calibrate the device. I have a lot of experience in spectrometry. I can help.

DIOS ESA LAMPARA ESTA MUERTA DEBES CAMBIALA
Sir AAS 240 instrument - abs Vs con ?
Do you guys have any advise how to fix no peak detected error under 30610 code?
Tengo 2 de esos equipos en mi trabajo.. crees que puedas responder a una duda?
En que trabajas? yo alomejor puedo ayudar, tambien trabajo en esto.
Pregunta lo que quieras... yo te lo explico facilmente. Conozco este instrumento de adentro para afuera.

Does anyone know how much the 200 AA cost? Please
"the flame is gonna be lit" heh ;-)
LOL I thought the same thing. it's lit!!
nice
so nice for explanation, but record not good!
Great explanations though buh I don’t seem to really understand
It's problem lamp blink
Please change lamp with new one.
