The Smart OMNI-Sampler accessory is ideal when you need to make fast and simple measurements but face a wide range of different sample types such as solids or liquids.
The Smart OMNI-Sampler is a versatile, single-reflection ATR sampling accessory that fulfills almost all application needs. In addition to routine solids and liquids, it facilitates the analysis of difficult samples, such as single polymer beads, hard rigid polymers and coatings on glass substrates.
The Ge crystal is extremely hard with excellent chemical resistivity. Ge is attacked only by Aqua Regia and hot sulfuric acid, making it well-suited to a variety of applications.
The Smart OMNI-Sampler accessory's domed sampling surface and choice of two fail-safe pressure devices provide good spectra on the first try, an unprecedented feature in ATR.
The unique, optional liquid holder extends the usefulness of the accessory. It can be attached easily, requiring no modifications to the accessory. The "swimming pool" design is optimized for small volumes and ease of cleaning.
Applications
Single, polymer beads
Formed, rigid polymers
Single fibers
Paint chips
Carbon-filled materials
Contaminants in paper
Liquids: aqueous solutions, corrosives and caustics
Features
Spectral range: 4,000 - 675 cm-1 (Ge)
Standard pressure device tip is 2mm diameter, which defines the effective spot size
Dome-shaped crystal design concentrates energy to a smaller spot size, allowing the analysis of smaller samples
Liquid holder allows small volumes of liquid to be sampled
