The VideoMVP™ Single Reflection ATR Microsampler from Harrick Scientific

The VideoMVP™ is designed to provide the user with all the benefits of a high performance diamond ATR accessory as well as video imaging and optional force sensing features.

The VideoMVP™ is designed with convenient horizontal sampling consisting of an active sampling area measuring less than 500µm in diameter on its monolithic diamond, thus making it suitable for infrared spectroscopy measurements of exceptionally abrasive powders, hard samples, beads, fibers and even corrosive materials.

The video imaging unit offers a magnified view of the sample in real-time via the ATR crystal. This image can be viewed either on the integrated display or digitally stored for a future reference.

Using the integrated pressure applicator, solid samples are packed together against the ATR crystal.

The pressure applicator is fitted with a slip clutch to avoid over-pressurization. An optional force sensor designed with digital read-out is provided if required for accurate measurement of the force applied to the sample and to reproducibly apply lower force than supplied by the built-in slip clutch.
