摘要： An optical resolver comprising an optically active substance made of tris-(2,3-epoxypropyl)isocyanurate, is presented. The optical resolver comprises an optically active tris-(epoxyalkyl)isocyanurate or its derivative, or an optically active derivative of a tris-(epoxyalkyl)isocyanurate. Particularly, the optical resolver comprises optically active tris-(2,3-epoxypropyl)isocyanurate or its derivative, or an optically active derivative of tris-(2,3-epoxypropyl)isocyanurate. Having supported on a carrier, an optically active tris-(2,3-epoxypropyl)isocyanurate or its derivative, or an optically active derivative of tris-(2,3-epoxypropyl)isocyanurate, can be made to be a packing for use in high-performance liquid chromatography, whereby efficient optical resolution can be carried out.

摘要： An indicator system provides a visual indication of the cumulative level of an airborne contaminant. The indicator is a transparent sheath with support medium having an acidic surface and treated with a color pH indicator. As a basic contaminant is adsorbed by the medium, the medium color changes. As additional contaminant is adsorbed, the color front progresses the length of the indicator. The indicator system may be used with an adsorptive filter system to predict the life of adsorption bed assemblies. A sample flow is taken upstream of the adsorption beds and is passed through the indicator. Preferably, the flow rate is calibrated so that the rate of the color change in the indicator is proportional to the rate of depletion of the adsorption bed. By monitoring the indicator, an accurate prediction of adsorption bed life may be made.
摘要翻译：指示器系统提供空气污染物的累积水平的视觉指示。指示剂是具有酸性表面的支持介质并用彩色pH指示剂处理的透明护套。由于基本污染物被介质吸附，介质颜色发生变化。随着附加的污染物被吸附，颜色的前沿会延长指示器的长度。指示剂系统可以与吸附过滤系统一起使用以预测吸附床组件的寿命。在吸附床的上游进行样品流动并通过指示剂。优选地，校准流量，使得指示器中颜色变化的速率与吸附床的消耗速率成正比。通过监测指标，可以准确预测吸附床的寿命。
