High Sensitive Analysis of Metal Bonded Amino Acids (2)

The investigation for metal bonded amino acid is remarkable study for metabolising metals is human body. Selenized amino asid is analyzed using GS320A-M5D and ICP/MS. The sensitivity of the analysis using micro column is higher than that using conventional type column.
Please refer to the page regarding the comparison of micro column and coventional type column.
