Harrick Praying Mantis DRIFTS

Introduction: The Forerunner in Spectroscopic Excellence

The Harrick Praying Mantis™ was the first generally available diffuse reflection attachment and remains the undisputed forerunner in the field. Its iconic design incorporates two 6:1, 90° off-axis ellipsoids that form a highly efficient diffuse reflection illumination and collection system. Designed specifically for the analysis of rough or powdered materials, the Praying Mantis™ maximizes diffuse reflectance collection while minimizing unwanted specular components, providing researchers with superior spectral quality.

Applications

The Praying Mantis™ is a versatile powerhouse used across diverse scientific disciplines:

• Catalysis Research: A fundamental tool for studying heterogeneous catalysis, gas-solid interactions, and adsorption/desorption mechanisms. It enables in-situ and operando monitoring of interactions between reactants and catalysts.
• Material Science: Ideal for characterizing MFI Zeolites (titanium incorporation), Metal-Organic Frameworks (MOFs), and semiconductors.
• Reaction Dynamics: Used to investigate photochemical reactions, oxidation mechanisms, and chemical kinetics under controlled environments.
• Astrochemistry: Analyzes the spectra of molecules like fullerenes (C60, C70) at extreme temperatures to understand cosmic matter.
• Electrochemical Integration: When used with specialized adapters, it allows for in-situ spectroelectrochemical studies of solar cells, fuel cells, and electrodes.
• Complementary Spectroscopy: Extends beyond FTIR to support Raman spectroscopy studies, offering complementary insights into catalytic processes.

Key Features

• Minimal Sample Preparation: A non-destructive, no-optical-contact technique requiring minimal prep work.
• High Surface Sensitivity: Highly sensitive to surface species, making it essential for characterizing complex surface reactions.
• Broad Spectral Range: Supports FTIR, UV-Vis, and NIR regions, compatible with advanced systems featuring automated source and detector switching.
• Extreme Environment Flexibility: Integrates with specialized chambers to control temperatures from -150 °C to 910 °C and pressures from high vacuum to 4 MPa.
• Efficient Workflow: Features PermaPerge™ for rapid sample exchange with minimal interruption to the system's nitrogen or dry air purge.
