Variable Angle Horizontal ATRMax II Accessory
The ATRMax II is a unique Variable Angle Horizontal ATR accessory permitting investigations over a range of incident angles from 25° to 65° with adjustable 1° increments. With the use of a flat or trough top plate, optical alignment is maintained at all angles of incidence.
Using the precision angle adjustment, the angle of incidence can be increased or decreased depending upon the sensitivity requirements of the solid or liquid sample. As the angle of incidence changes the number of reflections, depth of penetration and absorbance intensity; the angle is selected to optimize sensitivity. Measured absorbance is directly related to depth of penetration controlled by the angle of incidence. A depth of penetration from 0.50 to 10μm can be achieved by varying the number of reflections between 3 to 12 while dependent on the crystal material, the angle of incidence, the sample’s refractive index and the infrared wavelength. Sensitivity can be further enhanced with the use of either a
manual rotating wire grid polarizer or a
automated wire grid polarizer.
The ATRMax II can be configured as an automated accessory. The automated option offers high performance and conveniently selects incidence angles that are programmed independently or simultaneously. Software is integrated to control motion and data acquisition.
Scroll below for order details. ATRMax II systems can include a flat or trough top plate or both (each assembled with a 7 reflection 56 x 10 x 4mm, 45° ZnSe trapezoid ATR element), flat plate clamp, volatiles cover, powder press and purge kit. Top plate assemblies with optional ATR materials (Ge, Si, KRS-5 and AMTIR) ) and a choice of incident angles (30°, 45° and 60°) are also available.
Add-on features include flow through top plates, heated top plates and a removable crystal top plate for analysis of coatings, monomolecular layers, or bio-films deposited directly upon the HATR crystal which can be easily cleaned for repeated usage.
