How do you prepare ppm standard for aas?
To prepare AA (atomic absorption) standards, it is sometimes necessary to prepare double dilutions from the original standard bottle, but not always.In order to obtain accurate results, it is very important to always do these two things: 1) Ensure that the standards being used are "NIST Traceable." The primary standards being used should have the phrase "NIST Traceable Standard for AAS," or "This AA Standard traceable to NIST." Or a phrase similar to these two.NIST stands for National Institute for Standards Technology. It is a US federal governmental agency that works with industries to develop and apply technology, measurements, and standards. As it applies to your question, NIST maintains the most accurate and precise standards for calibration of AAS instrumentation. 2) If you plan to prepare multi-element standards, it is important to refer to the information that came with the AA primary standards you plan to use. Better is to purchase the needed multi-element standards in the first place, even if they contain a few elements in which you are not interested. This is because the soluble salt of one element that was used to prepare its primary standard may not be compatible with the soluble salt of another element in its primary standard. For example, let's say that you want to make an AA standard containing silver and copper, so you add the appropriate volumes of NIST-traceable copper chloride and silver nitrate standards. If someone prepared a standard this way, then it is likely that he will not even be able to calibrate the AA instrument for Ag, depending on the relative Ag and Cu concentrations. If the AA is calibrated for Ag, then the reported results will biased very high since AgCl is completely insoluble for AA purposes.To prepare a standard from a primary standard bottle, simply use the equation:V1·C1 = V2·C2 where V and C represent Volume and Concentration respectively. Thus, if you wish to make 1.00 L of a 2.00 ppm solution and the concentration of the primary AA standard is 100 ppm, then the only unknown term in the equation is V1, the volume of the primary standard needed. V2 is 1.00 L or 1000 mL, C2 is 2.00 ppm, and C1 is 100 ppm. Solving the equation for V1 = (1000 mL)(2.00 ppm)/(100 ppm) = 20 mL. Therefore, you need to add 20.0 mL of the primary standard to a 1000 mL volumetric flask and carefully add enough deionized water, shaking occasionally, so that the final volume is 1000 mL, not 1002 mL.
What are the best ways to prepare you child for college?
Encouraging your child to take Advanced Placement courses in high school will better prepare them for the harder academic standards of a college. To prepare them for dorm life/making responsible life choices, talk with them about the dangers of drug and alcohol abuse often.
What are the steps that are necessary to prepare the work area according to health and safety standards?
The answer to this question depends entirely on what work is to be performed, where it is to be done, and with what tools.
