Fourier-transform infrared spectroscopy (FTIR) can be used to obtain an infrared spectrum of absorption or emission of a solid, liquid or gas.

The Shimadzu IRTracer-100 has great sensitivity, speed and resolution.

The IRTracer-100 features the SN ratio of 0.25cm-1 resolution, and high-speed scanning capable of 20 spectra/second.

High-Sensitivity Measurements, with the highest SN Ratio
Trace a mounts of silicone oil in paraffin oil were measured using the IRTracer-100 and a single-reflection ATR accessory.

Even the very weak peak (1260 cm-1) from the silicone, with a mere 0.00015 Abs, was measured with a high S/N ratio.

Measured with a resolution of 4 cm-1, using the DLATGS detector

Highly accurate quantitation and identification can be achieved with 0.25 cm-1 resolution. For example, this resolution is suitable for the detailed analysis of each peak in a gas sample. When ammonia gas was run at 0.25 cm-1 resolution, peaks in the 805 – 810 and 785 – 790 cm-1 ranges were clearly resolved.

The rapid scan function allows a maximum of 20 spectra per second to be obtained. This makes the IRTracer-100 suitable for fast reactions that occur within a few seconds and for kinetic studies occurring in less than one second. Rapid, high-sensitivity analysis is available.

The IRTracer-100’s interferometer is optimized and stabilized using a combination of a smooth moving mirror system and the Advanced Dynamic Alignment. To assure that the IRTracer-100 is always in the optimum operating condition, a self-diagnoses routine monitors the operation of the system at initialization and constantly during operation In addition, standard EP/CHP/JP/USP/ASTM validation programs are provided to evaluate the FTIR performance.

Incorporation with Advanced Dynamic Alignment

The smooth moving mirror system monitored by the Advanced Dynamic Alignment system allows the IRTracer-100 to provide optimum and stable quality spectra after only a short warm-up time. Sampling at over 5000 times /second the Advanced Dynamic Alignment keeps the IRTracer-100 in optimum operating condition. In addition, the Advanced Dynamic Alignment system automatically aligns the interferometer when the beam splitter is changed for NIR or FIR analysis.

Four Benefits of Advanced Dynamic Alignment

■ Removes the influence of environmental variations
■ Shorter warm-up times and enhanced stability

Beam splitters used in FTIR interferometers are susceptible to humidity. In order to maintain the long-term stability of the interferometer, the beam splitter must be protected from moisture. To address this issue, the IRTracer-100 has been engineered with an airtight interferometer that incorporates a unique internal Automatic Dehumidifier.
