Smart OMNI-Sampler™ Germanium ATR Sampling Accessory

Thermo Scientific™ Smart OMNI-Sampler is a good choice when you need to make fast and simple measurements but face a wide range of different sample types—solids or liquids. The Smart OMNI-Sampler is a single reflection Germanium ATR sampling accessory that fulfills a wide array of application needs. In addition to routine solids and liquids, it facilitates the analysis of difficult samples, such as dark carbon-filled samples, single polymer beads, hard rigid polymers, and coatings on glass substrates. The Smart OMNI-Sampler is a cost effective alternative to diamond sampling accessories. It is as easy to use as position, click, and scan.

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
