General Spectroscopy - Differences between ICP and AA standards

 
Can an ICP single element standard be used for AA techniques? What is the main difference between and ICP and AA standard? Is it that AA standards are less pure?

It is better for the one who knows it well and is an expert to explain the difference between ICP and AA. It's not like an Intex Coupon Code, So not everyone should comment It has to do with people's health. Anyway, Google is getting tough on what is being medically commented on.

Inorganic ventures have a forum about general Spectroscopy with differences in ICP and AA standards. And now you can get help from assignmentmasters to manage the quality tasks. You can get the critical teams for standard equipment. The AA standards are generally certified as 1000 ug/mL. Join it for more details.

Yes, an ICP standard can be used for AA methods. Purity for AA standards is not as critical as it is for ICP methods, but for many of our products the AA purity is the same as that of the equivalent ICP standard. The biggest differences are related to the certification. Industry practice is for AA standards to be certified with nominal concentrations and fixed uncertainties, and 1000 ppm AA standards are generally certified as 1000 ug/mL +/- 10 ug/mL regardless of the lot or element. That’s our practice at IV; 1000 ug/mL +/- 10 ug/mL (nominal concentration +/- 1%) is the certified value for our stock 1000 ppm AA products.  The certified values for ICP standards vary (are specific to a lot) and result from more rigorous testing. They represent specific test results, calculations, or both, and account for factors such as stability and homogeneity when assigning the final concentration and uncertainty. As a result ICP standards are both more accurate and precise.
