Sampling was made in TAC GIREDMET.
The determination of atomic fractions was made by Spark Source Mass Spectrometry. The JMS-
01-BM2 double focusing mass spectrometer manufactured by JEOL (Japan) was applied. The high
resolution mass spectra were photographed on Ilford-Q plates. Joyce Loeble (United Kingdom) MDM6
microdensitometer and NOVA 4 (USA) on-line minicomputer were used for the mass spectrum lines
identification. Quantity estimation was calculated by original MS Lab software. The relative standard
deviationi s 0.01-0.05f or isotopea bundancem easuring.
The results are presented in atomic percent.
Isotopic Abundance of Copper corresponds to natural
