Dynamic range ?

hello ! im trying to find out what is dynamic range for this instrument ?

running EPA 300.1 method for bromate and bromide any idea were I can find

 this info ? so far I find out that is up to 15000  uS/cm how to relate this to mg/l or ppb ? any help grealty appruciated !

Thanks will tray go for 1ppm to be on safe side.

You can go for multipoints calibration linearity will not get affected. one thing that never inject 100 ppm to column. less than 50 ppm. because some time column will get overloaded.

I have a idea but I do need numbers like I think lowest will be about 2-5 ppb but what about high end?

Any idea 10, 100 or more ppm before affecting linearity when starting with 5 ppb ?

if you go for PPM concentration you will get 0.999 linearity and in same plot if you go for ppb linearity will get affected

But any ideaat what concentration  linearity will be affected ?

you can go for ppb& ppm linearity in conductivity. nice reponds in detector and calibration plot in linear .
