PIKE Technologies NIR IntegratIR
A near-infrared (NIR) Integrating Sphere for quantitative and qualitative measurements of a wide variety of solids and paste materials. The NIR IntegratIR collects reflected energy from a spherical perspective and thereby captures complete and quantitative response from the sample. Using near-infrared chemometrics, qualitative product identification and quantitative analysis may be performed on pharmaceutical, nutraceutical, chemical, polymer, textile, food, agricultural and other samples. The NIR IntegratIR accessory features a 2″ high reflectivity gold-coated integrating sphere and a high-speed, low-noise indium-gallium-arsenide (InGaAs) detector, transfer optics and interface electronics.
The NIR IntegratIR fits into the sample compartment of most commercial FTIR spectrometers and its electronics interface as an external detector of the spectrometer. A 10 mm diameter horizontal sampling port makes the placement of samples onto the accessory very easy. An optimized borosilicate window serves as a sampling port at the top of the integrating sphere. The window is bonded and sealed to protect the sphere from corrosive materials and contamination.
Sampling of tablets, packaging materials and plastics is easily accomplished by placing the sample directly on the window of the upward facing sphere. Powders, creams, pastes or liquids containing reflective particles may be placed in disposable flatbottom vials – eliminating the need for any sample cleanup. The vials may be held in place by a sample-positioning vial holder, resulting in more repeatable measurements.
High quality spectra are produced quickly using the NIR IntegratIR – making qualitative and quantitative analysis of a wide variety of sample types efficient and reliable. For heterogeneous samples, PIKE Technologies offers a Rotating Stage for the NIR IntegratIR. With this option, one obtains an averaged result to eliminate variations in quantitative results for the chosen sample area.
The NIR IntegratIR comes complete with diffuse gold reference, sample holders and a removable general-purpose sample mounting plate. The NIR IntegratIR is configured for each specific FTIR spectrometer and includes a pre-aligned mount for your instrument. The NIR IntegratIR is a cost-effective, high-performance sampling option for laboratories with a standard FTIR spectrometer equipped with a near-infrared light source and beam splitter. The optional transmission tablet analysis stage for the NIR IntegratIR provides an automated tool for sampling 10 tablets of a variety of sizes. With this option you can measure formulation reproducibility or verify pharmaceutical composition.
