Want current fluorometric data in a cumulative handbook?

If y o u do, we'll be glad to put y o u r n a m e o n o u r distribution list to get the f o l l o w i n g i n f o r m a t i o n as we p u b l i s h it : • data sheets o n decay t i m e s • application n o t e s • instrumentation techniques • digests of pertinent papers Direct decay time measurements of fluorescent properties, only calculated by older methods, are being generated by TRW Nanosecond Spectral Source System users in physical, chemical, biological, and medical labs and by our applications research staff. This material is yours for the asking, pre­ punched to fit an attractive 6 x 9 stiff binder. Clip the coupon below and mail it to us.
