Abstract
The analytical chemist is ever eager to improve and expedite present analytical methods.. In the past ten years considerable interest .has been elicited in the field of high frequency oscillators and their application to analytical chemistry. One of the main reasons for this interest is the uniqueness of the apparatus. No direct contact is made between the measuring instrument and the solution. Credit tor this interest must be given primarily to Jensen and Parrack of Texas A & M University. Their article in 1946 described a simple tuned plate-tuned grid electronic oscillator, operating in the high frequency range. A solution was exposed to t he electromagnetic field or the plate coil. During the titration the electrical characteristics of the solution changed. These changes were reflected in measurements of the electrical constants of the oscillator. Upon analysis the constants clearly showed the end point and yet no physical contact had been made with t he solution. Since the instrument of Jensen and Parraok many modifications have appeared and even entirely new instruments. However they still keep the one common feature: no contact with the solution. In addition to titrations, the instrument has been used to advantage in many other fields of analytical chemistry. After ten years it has clearly established itself as a valuable tool rather than just a laboratory curiosity.
The object of this present research was to build an original instrument and test its effectiveness in as many fields as possible.
