Leading the way in material characterization Multi-Sample UV Irradiator Multi-Sample UV Irradiator (UV-1048E) is an option for Micro UV Irradiator (UV-1047Xe). This system can simultaneously irradiate a maximum of 18 polymer samples in the irradiation chamber for increased efficiency in accelerated deterioration tests of polymer samples using UV/Py-GC/MS system. The sample cup holder is rotated under the irradiation of UV light for uniformed irradiation. The temperature of polymer samples are controllable from 40 to 80 ºC. Features • Simultaneous irradiation of multiple samples Up to 18 samples can be simultaneously irradiated by UV light . • Small size and easy handling This bench-top size system offers simple and easy handling. • EGA or flash pyrolysis of irradiated samples Using UV/Py-GC/MS system, the irradiated polymer samples can be analyzed by EGA (Evolved Gas Analysis) or Py-GC/MS analysis.

Comparison of deterioration rate between UV-1048E and UV-1047Xe by UV irradiation Sample temp. under UV irradiation : 60 ºC Sample : 200 μg (thin film) Upon UV irradiation, the thermal property of HIPS changes as the peak shape of EGA thermograms becomes broader by UV irradiation than that without UV irradiation. The peak shape of HIPS under 12 hours UV irradiation using UV-1048E is the same as that under 1 hour UV irradiation using UV-1047Xe. This indicates that the rate of deterioration by UV1048E is about 1/10 of that by UV-1047Xe. The figure on the left compares EGA thermograms of high impact...
