Abstract
A plasma spectroscopy analysis method includes a preliminary addition process in which a bonding agent that is an agent other than DMSA is added to the specimen collected from a living body to which meso-2,3-dimercaptosuccinic acid (DMSA) is administered, a concentration process in which the analyte heavy metal ions in the specimen at a vicinity of one of a pair of electrodes by applying a voltage to the pair of electrodes, and a detection process in which plasma is generated by applying a voltage to the pair of electrodes, and luminescence of the analyte metal ions caused by the plasma is detected.
Claims1
A plasma spectroscopy analysis method, comprising:
- a preliminary addition process including adding ethylenediaminetetraacetic acid which is capable of bonding with lead ions to a urine specimen collected from a living body, the living body having been orally administered with meso-2,3-dimercaptosuccinic acid before the preliminary addition process;
- a concentration process including concentrating the lead ions in the urine specimen at a vicinity of one of a pair of electrodes by applying a first voltage to the pair of electrodes;
- and
- a detection process including generating plasma by applying a second voltage higher than the first voltage to the pair of electrodes, and detecting a luminescence amount of the lead ions caused by the plasma and quantifying the lead ions in the urine specimen based on the luminescence amount of the lead ions.
