应该是聚苯乙烯。
影子用的红外是什么牌子的?
以iS10为例,称之为validation wheel,包括聚苯乙烯薄膜和NG11玻璃,
是内置于仪器内部的,仪器运行系统适配性时自动调用。
The 1.5 mil polystyrene is traceable to NIST SRM 1921a, and the NG11 glass is traceable to NPL Schott NG11. Analysis methods are based on ASTM E 1421-99 (2004) Standard Practice for Describing and Measuring Performance of Fourier Transform Mid-Infrared (FT-MIR) Spectrometers: Level Zero and Level One Tests.
