VideoMVP™ Single Reflection ATR Microsampler

The VideoMVP™ offers all the advantages of a high performance diamond ATR accessory plus video imaging and optional force sensing capabilities. The VideoMVP™ features a convenient horizontal sampling with an active sampling area of less than 500 µm in diameter on its monolithic diamond. This makes it ideal for infrared spectroscopy measurements of extremely hard samples, abrasive powders, fibers, beads, and even corrosive materials. The video imaging system provides a real-time magnified view of the sample through the ATR crystal. This image can be seen on the built-in display or digitally captured for a permanent record. Solid samples are compressed against the ATR crystal using the built-in pressure applicator. The pressure applicator features a slip clutch to prevent over-pressurization. An optional force sensor with digital read-out is available for precise measurement of the force applied to the sample and to reproducibly apply lower force than delivered by the built-in slip clutch.

VideoMVP

The VideoMVP is a high performance diamond ATR microsampler with real-time imaging of the sample. This makes it ideal for examining fibers and other small samples via infrared spectroscopy. Not only is positioning minute samples simple and straightforward, but the imaging system allows observation of the ‘wetting’ of the crystal as pressure is applied in addition to photographic documentation of the area sampled.

The VideoMVP comes with a diamond ATR crystal with a 500 µm sampling area. This ATR crystal is mechanically retained in a chemically resistant sample holder. The integrated LCD display provides a 120X magnified image of the sample and the display tilts for easy viewing. The imaging system can be connected to a computer using the supplied adapter to record and store the image.

The basic configuration comes with a built-in slip clutch which is designed to apply sufficient force for quality spectra with a over-pressurization limit. An optional force sensor is available for more accurate and repeatable pressure application.

Sample spectra recorded with the VideoMVP are shown in Figure 1 through 3. Figure 1 shows the spectrum of cotton fibers, recorded with the maximum pressure applied by the VideoMVP. From the imaging system, it is possible to see the fibers compress against the crystal as pressure is applied. Figure 2 shows the spectrum from a ridge on a plastic bag. From the spectrum, it is clear that the ridge is composed of polyethylene. Figure 3 features spectra recorded from two different locations on a credit card. The two sections are visibly different, but the spectroscopic differences are small.

Figure 2. ATR Spectrum of a Ridge on a 2”x3” Ziplock Bag.

Figure 3. ATR Spectra from two locations on a credit card. The inset photographs are bordered by the color of the corresponding spectrum.

As demonstrated, the VideoMVP is ideal for examining a wide variety of small samples in addition to focusing in on details on larger samples.
