Accuracy and Precision

[Wintergreen]

Hello all!

Newbie here - Please help.

I'm using Dionex AS11 (for F,MSA,Cl,Br,NO3,SO4,PO4) and CS17 (for Na,NH4,K,Mg,Ca) columns for analysing environmental samples. I have standards for all the mentioned ions seperately. Can someone share their knowledge on Accuracy and precision of the instrument/study (im not clear here with the usage of both the terms). What is instrument error? How would i determine them for my studies?

Please post back soon.
Thanks
