We have a new electrometer especially for lab chromatographs.
how much impurity do you want? Few people want or need really PURE water. Although IWT can engineer a mixed-bed water system which delivers pure water (.000000043 ppm impurity) it probably wouldn't be practical for you. A funny thing happens to pure wateron the way—itscavenges any material it touches to satisfy its solvent hunger. It won't stay pure.
(Check the linear dynamic range.) The linear dynamic range of our new electrometer is 10 7 . And the total range is 10 1 0 (from 1 x 1 0 1 4 A. to 1 x 10- 4 A . ) . You'll find its junction field effect transistor circuitry highly reliable. It's c o m pletely solid state, has extremely low noise and is steady as a rock —drift less than 1 0 1 3 amperes a day. The input attenuator has five positions, five decades. The recorder output attenuator has 16 positions with a total range of 10 5 ( 1 0 0 , 0 0 0 times). Can your integrator handle the linear dynamic range of this electrometer?

To get it pure and to keep it pure costs too much. So, it becomes a matter of which and how much impurity you can accept. When it comes to producing volumes of almost pure water economically, that's where IWT sparkles. We can engineer a system that makes the most of your impurities.
