Can anyone give feedback about the performance of Perkin Elmer ICP OES 8000 series .
kind regards,

We are planning to buy new ICP OES . We are analytical lab dealing with food, dairy, animal feed samples.
We need to check major elements such as Ca, P, S, K, Na, and minor elements such as Cu, Zn, Mn, Co, Cr etc. We also want to check Heavy metals such As, Pb, Cd, Hg, Al, Sn, Se, Mo. The concentration of these metals in digested sample solution would be around 5 ppb to 200 ppb. Can we achieve this detection level on ICP OES. Kindly advice.

Depends on the way you calculate your LOD/LOQ, but realistically, you'll never reach 5 µg/L LOQs for As, Se, Hg, Pb and Sn with the normal setup on real-life samples - this is the truth for most, if not all, ICP-OES machines.

Be sure i have give my suggestion...
The Optima™ 8x00 series is more than just an evolution of the world’s most popular ICP-OES… it’s a revolution. Built around the proven design of the Optima platform, the 8x00 series delivers breakthrough performance through a series of cutting-edge technologies that enhance plasma stability, simplify method development and dramatically reduce operating costs:
The Optima 8x00 is available in two models:
Optima 8000
Optima 8300

Dear Sir,
Thanks a lot. Which model you have been using? and what is lowest level of As, pb, Se you can detect in digested sample solution. Is it less than 50 ppb ?

Realistically, on digested samples, you'll be able to achieve LOQs (expressed as 10*sR) of between 10 and 20 µg/L in solution for the metals you mentioned.

You can easily meet these requirements, even lower as suggested by Sven1982. Normally in the range of 2-6ppb.You can optimize the integration times for these analytes. For As and Se you can also consider to use hydride generation. PerkinElmer has an own hydride kit, basically from the FIAS/FIMS unit and can directly be coupled on the Optima. Also ESI onffers very nice solutions for hydride generation.
