extracts of urine and fertilizer. Therefore without a confirmation of
the presence of trace amounts of urea nitrate, a conclusion can not

evidence. Such a confirmation technique is not known to this

Specimen Q23 was also analyzed with solid probe mass
spectrometry to determine the presence of residues of urea
nitrate. The results of this analysis were consistent with the
presence of urea and nitric acid. However, these materials are
also found from this analytical method following analysis of other
materials such as extracts of urine and fertilizer. Therefore without
a confirmation of the presence of trace amounts of urea nitrate, a
conclusion can not be rendered concerning the presence of this
material on the evidence. Such a confirmation technique is not
