This has to be the ultimate for analysing liquids. This
technique is very under rated and consists of a packed column with high
pressure pumped eluent and a sensitive detector.
One column will separate all the anions such as metal
Another column will detect all the cations, such as nitrate, nitrite etc.
A different column will detect all the pesticides
Lots of other columns, designed to detect any type of material
as long as it is a solution, we can test it with incredible accuracy, quickly
and efficiently
