THE AUTOMATIC TITRATOR THAT GIVES YOU THE ANSWER WITH THE FLIP OF A SWITCH Introducing the newest, most accurate analytical technique for automatic coulometric titration, the Petrolite® Ion Trak™ Analyzer from Petrolite Instruments. This compact, highly versatile analytical instrument eliminates standardization and the need for prior knowledge of the end point potential. Utilizing the "Rate Controlled Titrimetry" technique, this easy to use, low cost instrument automatically regulates the coulometric generation of a titrant in such a manner as to linearly control the rate of potential change at the sensing electrodes and automatically ceases the titration at the equivalence point. The answer is then read out directly on the integrator display in equivalents, grams of NaCI , or grams of Chloride.
Typical sequence for a routine analysis : 1. Add Sample. 2. Place Mode Select switch in AUTO TITRATE position. 3. Read result on intergrator display. 4. Repeat above steps for your next sample.
