Random Cuttings & Spectroscopic Powders

(27)
KBr powder is graded solely by purity standards that are relevant to infrared spectroscopy. We do not use such terms as 5 9s (99.999%) , 6 9s (99.9999%) as the means used to test material for such certifications, such as emission spectroscopy, do not detect the types of contaminants that produce absorption bands in an infrared spectrophotometer. In the industry, the highest specification for transmission optics is beam splitter grade material which is generally specified by FTIR spectrophotometer OEMs as material having absorption bands due to impurities of less than 1% measured at 4 wave resolution between 4400cm-1 and 450cm-1. The cut off for commercial grade KBr crystal optics at ICL is material having absorption bands due to impurities ...

Magnetic Film & KBr Pellet Holders

(4)
Magnetic holders are convenient for holding KBr pellets or thin polymer films. They are also useful for mounting a 13mm crystal that has been used as a microscope slide in a standard spectrophotometer sample compartment. The film sample, pellet or optic is held in place by a magnetized rubber plate. These holders fit the universal 2" x 3" slide mount in all spectrophotometers. Use of paper inserts facilitates mounting small samples.

Econo Cards

(2)
ICL’s popular Econo Cards are an ideal vehicle for mounting KBr pellets and polymer films or for use with disposable polyethylene IR transmission windows. They are available with 19mm and 9.5mm circular apertures. Econo Cards have a pressure sensitive adhesive on the inside surface, but the adhesive is kept away from the aperture and outside of the path of the spectrophotometer beam to avoid spurious absorbance peaks. The sample is mounted on the adhesive surface and the card then folds over into a 2" x 4" card that can be inserted in the slide mount in any spectrophotometer or used to store the sample for future reference.

Agate Mortars and Pestles

(8)
ICL’s agate mortars and pestles are the ideal tool for grinding a matrix of a solid sample with KBr powder in preparation for making a transparent pellet free from spurious absorption peaks.
