| For Rapid Screening Analysis |
Energy Dispersive X-ray Fluorescence Spectrometer
EDX-720 |
 |
Energy Dispersive X-ray Fluorescence Spectrometer enables the simple, rapid analysis of metals, resins, powders and liquids at the ppm level without pretreatment. EDX-720 is also capable of rapid screening of total Cr and total Br. |

Atomic Absorption Spectrophotometer
AA-6300 |
 |
Dissolve the sample in purified water, weak acid or organic solvent and heat the samples is all that is required to perform high-sensitivity measurements of toxic metals. Measurement is possible not only of toxic metals that were added intentionally, but also of toxic metals contained within substances as impurities. |

| Hazardous Substances: Brominated Flame Retardants |
| |
| For Rapid Screening Analysis |
Fourier Transform Infrared Spectrophotometer
IRPrestige-21 |
 |
Using a single-reflection ATR accessory and a bromine flame retardant identification macro program enables the identification of plastics and brominated flame retardants in a matter of tens of seconds. The lower detection limit is of the order of a few percent (concentration) and so this method is used in screening applications. |

Gas Chromatograph Mass Spectrometer
GCMS-QP2010 |
 |
The constituents of brominated flame retardants are separated with a gas chromatograph and detected with a mass spectrometer. This makes it possible to analyze brominated flame retardants with a high degree of precision. In order to ensure high accuracy, however, samples must be treated beforehand to remove resins or other substances that may obstruct analysis. |

| Hazardous Metal: Hexavalent Chromium |
| |
| Hexavalent-chromium Selective Analysis |
UV-VIS Spectrophotometer
UVmini-1240 |
 |
The sample is placed in boiling water for sample pre-treatment. The hexavalent chromium is then extracted and measured with the UVmini-1240 and Water-quality Measurement Program Pack using diphenylcarbazide absorption photometry, and the amount of hexavalent chromium is obtained. (See note.)
Note: Although extraction using, for example, boiling water is necessary for measuring the hexavalent chromium (e.g., in screws), the total amount of hexavalent chromium cannot be extracted in this way. The concentration obtained with diphenylcarbazide absorption photometry does not necessarily reflect the total amount of hexavalent chromium contained in the sample. |
