PerkinElmer's Diffuse Reflectance Accessory (L1200351/L1600111/L1280323) comes with abrasive sampling tools that allow you to collect ready-to-analyze dust samples from hard-surfaced solid materials. The Diffuse Reflectance Multi-Purpose Sample Holder (L1201865), designed to hold either an abrasive stick or pad, easily slides into the diffuse reflectance accessory. The holder can accommodate up to two sticks or two pads; the first tool with the sample dust goes in its sample position, the second tool, in its reference position.
