MirrIR Microscope Slides
Kevley Technologies’ MirrIR microscope slides reflect 95% of mid-IR radiation with no interfering absorption or mathematical corrections. Solid, liquid, organic, and inorganic materials can be applied to the surface. Multiple samples can be easily distinguished on a single slide due to the high contrast between the samples and the visibly clear glass surface. Spectra are obtained in the reflective mode with a simple focus and scan procedure. The standard 1 x 3 inch slides are supplied in boxes of 25.
MashIR Flattening Tool
Kevley Technologies’ MashIR flattening tool is used for solid sample preparation. Samples can be pressed flat on the slides surface by simply rolling the tool over the sample while applying hand pressure. The MashIR flattening tool is compatible with fibers, minerals, polymers, organic, and inorganic solids. Intimate contact with the slide surface is necessary to produce quality spectra. The MashIR flattening tool provides diamond cell performance with simple preparation at a fraction of the cost.
Did you know?
MirrIR low-e microscope slides for reflective infrared studies have no interfering absorption from 4000 to 400 cm-1. This powerful sample preparation technique was featured in the June 1997 issue of “Spectroscopy” in the Sampling Solutions section. Infrared microscopy was never easier than with this simple, fast, and cost effective technique for organic and inorganic materials whether liquids or solids. Only microgram quantities are needed which makes it particularly useful for failure analysis and forensic investigations.
MirrIR low-e microscope slides are supplied in a standard 1 x 3 inch (25 x 75 mm) format. However, other sizes and shapes can be custom fabricated. There are no significant differences from slide to slide, so background spectra are not unique as with other sample preparation methods.
Low vapor pressure liquids can be applied to the low-e surface as a “smear” so that a thickness gradient is created. The spectrum can then be obtained at different sample thicknesses until the desired spectral intensity is observed.
Solid materials are most easily sampled by starting with small amounts of material and crushing or flattening the material against the low-e surface with the MashIR flattening tool. This technique makes sample preparation simple by ensuring a portion of the sample being scanned is in contact with the glass.
MirrIR low-e microscope slides can also be used on a standard IR bench with a specular reflectance accessory. When used in this way only liquids or coated samples can be used and larger samples are required. The original research was done on a bench before an IR microscope was used.
