Description
For Use With (Equipment): Nicolet FT-IR Instruments
Type: OMNI-Sampler, Lightning Viewer
Unit Size: Each
Performance Features
• Extremely rugged germanium ATR crystal has a spectral range of 4000 to 675cm^-^1
• Domed crystal design produces a nominal 2x reduction in the beam diameter to provide: enhanced sensitivity, the ability to run smaller samples and the ability to ensure optimal contact by exerting more pressure on the sample Point-to-point contact facilitates the analysis of hard, rigid, unyielding, and difficult-to-analyze samples Germanium crystal gives a shallow depth of penetration that is ideal for highly absorbing carbon filled samples, and thin surface analyses
• Tilt back pressure tower for easy access to crystal for cleaning and sample positioning Slip-clutch mechanism ensures that the correct pressure is applied every time
• Liquid holder can be attached easily and is optimized for small volumes and easy cleaning Specifications Crystal Material: Germanium; spectral data down to 675 cm^-^1 Sampling Area: 2mm diameter Crystal Angle: 45° (single reflection) Depth of Penetration: Approximately 0.67μm at 2000cm^-^1 Useful pH Range: 1 to 14 Sample Volume: 1.86mL Pressure Device: Tilt-back pressure tower or Lightning Viewer, both with fail-safe mechanism to prevent crystal damage The optional Lightning Viewer allows precise positioning of very small samples on the germanium surface. The Lightning Viewer features a sapphire surface and allows application of the same “turn and click” slip clutch pressure as the standard pressure device. Recommended for:
• Single polymer beads
• Single filaments
• Formed, rigid polymers
• Paint chips
• Printed circuit boards
• Paper/contaminants
• Carbon-filled materials (o-rings)
• Liquids, including aqueous solutions, corrosives, and caustics
