dividual instruments for a chemical company, because the price would be too high. We can build an in dividual instrument only if it is to be a prototype for a later wide sale or if it gives us basic knowledge for some ultimate instrument. In gen eral, we cannot do a profitable busi ness making instruments for only one company's needs, because the number would be too small to war r a n t the development expense. Be fore we can embark on a first proto type, we generally must have some assurance on future wide sale. This is a decision we have to make our selves and the best way is a market survey. B u t the market survey may not be possible without violat ing some confidential aspect of the chemical company's project which gave rise to the instrument need. Incidentally, we have found one approach to the single instrument problem if the development is not confidential. We have on occasion agreed on a price for the first instru ment a t or somewhat below cost, if the customer will agree to help us sell a limited number of similar in struments. If this number is sold, a portion of the income is returned to the first customer to reduce his costs. However, such an approach is not always feasible. Therefore, as a first point, I do not believe a cooperative relation can exist at present whereby an in strument company or companies can supply all the instrument de velopment needs of a chemical com pany. The chemical company must carry some development capacity in this area and this fact must be recognized. A second problem that must be appreciated is t h a t the rate of de velopment and production by the instrument company will seem slow to the chemical company, and the more pressing the need of the chem ist, the greater this irritation. Here again, the problem is essentially t h a t of low cost for wide sale com bined with reliability. The chemi cal company is looking at its own need and its need is usually a small quantity of instruments. If a deci sion has to be made, say for a valve to be used in the device, the small lot aim would dictate t h a t one buy
