FIND REFERENCE : Mahin and Lofberg; Anal. Biochemistry; 16, page 500 (1966)
   This reference is similiar to the above. It also includes perchloric acid.
   Both methods, given the strong oxidizing agents, can loose sample
   (exploding vials/caps). Both methods will produce chemiluminescence
   (extreme). 
   A common technique for the past 10 years has been elution using commercially
   available solubilization reagents. With the elution technique, approx. 82%
   or better recovery can be obtained, which is only slightly less than the 
   Mahin Lofberg technique.
