The human blood serum has often been used as a medium for diagnoses of various diseases based on elemental composition. In this paper, elemental identification and analysis of human blood serum have been performed using a standard LIBS technique utilizing 355 nm Nd: YAG laser under He surrounding gas. Experimentally, human serum was homogeneously dropped on a copper metal plate to produce a thin film. The film was then evacuated in a sample chamber, which is filled with He gas at 5-3 torr. A Nd:YAG laser was bombarded on a film to produce a breakdown plasma. Some elements in the serum from the normal and tuberculosis (TB) patients have successfully been identified, including C, H, O, Ca, and Na. The analyte intensities from the human serum of TB patients have good stability with laser shot dependence in different positions. A preliminary test to distinguish the TB patient from normal patient was made based on Ca elements in the blood serum. Namely, the Ca intensities from TB patient is much higher than the case of a normal patient. [ABSTRACT FROM AUTHOR] |
