The Praying Mantis Diffuse Reflectance accessory, for use with the Evolution 300 and Evolution 600 UV-Visible spectrophotometers, provides the ability to characterize very small quantities of solid materials or powders. Traditional diffuse reflectance accessories require large volumes of powders or solids appoximately 1/2" in diameter. The Praying Mantis, allows a diffuse reflectance measurement on samples as small as 3 mm in diameter.
Product Detail
High-Performance Design
The Praying Mantis accessory uses all-reflective optics rather than traditional integrating spheres in its design. Integrating spheres limit the wavelength range in the ultraviolet region. With an all-reflective optical system, you can use the full wavelength range of the instrument. In addition, the Praying Mantis is available for use on the Evolution 300, which has an upper wavelength range of 1100 nanometers. This means you can have the advantage of the extended wavelength coverage in the NIR region without having to purchase a more expensive UV-Visible-NIR instrument.
Flexible Sampling Options
The sample chamber can be purged with an inert gas such as dry nitrogen, which allows the characterization of samples that may be oxygen- or moisture-sensitive. Optional reaction chambers are also available for the study of samples at a wide variety of temperatures and pressures. Temperatures can be controlled from –150°C to 600°C, and variable vacuum control is available.
Convenient Analysis
The Praying Mantis accessory was designed so you can use it with the sample compartment open. This feature provides an extra level of convenience for mounting and removing samples. It also makes it convenient for mounting the low/high temperature reaction chamber for temperature studies.
