Dear Prof. Lederberg:

Dr. Allan Duffield of your department has informed me that you
plan to obtain additional apparatus that would provide high resolution
GC/MS as a service to the Stanford community.

We have in the past used the hospitality of your department in the
identification of metabolites and derivatives of phenothiazine drugs and
cannabinoids by GC/MS. Originally, we had the collaboration of Dr. B.
Halpern and more recently Dr. A. Duffield, who was instrumental in
helping us with some of our problems.

Our department would indeed be most interested in availing ourselves
of GC/MS analyses in the course of our current NIH projects which again
are concerned essentially with drug metabolism and the isolation and
characterization of unknown drug derivatives.

As a rough estimate, I would think that we may be interested in

the analyses of about five samples per month, two of which will require
high resolution MS.

I certainly hope that your project to acquire the sophisticated
new instrumentation you are seeking will be successful.

Sincerely yours,
