shimadzu vibrating mill for mix sample with kbr

APPLICATION Shimadzu News 2/2007 Solid analysis

with a vibrating mill and mixed with 200 mg of IR grade KBr (around 1 % of pellet weight), a KBr pellet is formed. in the sample may no longer be apparent as it was found when using dry ashing. Separation with heavy-liquid shows the benefit of the treat-ment: see result of the top right spectra in comparison with the SRM Chrysotile (lower right).

Measurement Methods for Powder Samples : SHIMADZU

Add one or two drops of liquid paraffin and mix to distribute the sample powder in the liquid paraffin. Apply the paste to a liquid cell (KBr crystal plate, etc.) and sandwich it under another cell plate. Since liquid paraffin exhibits absorption near 3000 to 2800 cm-1, 1460 cm-1, 1375 cm-1, and 730 cm-1 as shown in Fig. 1, hexachlorobutadiene is used to confirm the sample absorbance in these

Specamill FTIR + DRIFTS Sample Mill Specac

The Specamill grinding accessory is designed to mix a solid sample with an excess of KBr powder for the preparation of powder samples prior to compression into KBr pellets for infrared study, such as FTIR. It can also be used to prepare samples for diffuse reflectance spectroscopy. The target particle size of the sample is at least 25 microns. Adjust grinding set for sample hardness. There are

Application of Diffuse Reflectance Infrared Fourier

Background spectra were collected using grade IR KBr ground by a Shimadzu vibrating mill. The spectral resolution was 4cm"1 and 240 interferograms per sample were collected. A Happ-Genzel apodization function was used. The mirror scan speed was 9 mm/sec. The signal was adjusted with the beam attenuator up or down to about forty percent of background throughput count. A layer of air-dried

Potassium Bromide an overview ScienceDirect Topics

The alkali-halide disk technique is another traditional transmission sample presentation method, in which an intimate mixture of the finely ground solid sample and dry powdered alkali-halide, most commonly KBr, is pressed into a self-supporting disk. Finely powdered dry potassium bromide will coalesce to form a clear disk with high transmission when it is pressed under high pressure in an

IRAffinity-1S FTIR Spectrophotometer from Shimadzu

It can also work with transmittance readings but it takes a lot of work to prepare the samples (pressing the KBr disk) so from our experience it was better to work with the diffuse reflectance accessory (you only need to mix the KBr with your sample). We have employed it mainly for the analysis of coffee samples (solid and liquid) targeting adulteration and quality evaluation. It has also been
