Rapid Scan Software and IRTracer-100


The new IRTracer-100 Fourier Transform Infrared (FTIR) spectrophotometer is a highly versatile instrument in combination with the new LabSolutions IR software. Combining high speed, sensitivity, and resolution with enhanced expandability and easy-to-use software, the IRTracer-100 quickly and easily obtains high-quality data for samples in such fields as pharmaceuticals, foods, chemicals and electronics.

Using the additional ‘Rapid Scan’ software, the IRTracer-100 demonstrates its advantages in fast kinetics analyses. Up to 20 spectra per second are recorded and are evaluated in terms of signal intensity, area, ratio of two signals according to intensity and area, as well as the TAC (Total Absorbance Curve). These values are basic requirements for kinetics analyses.

The resolution, the number of measurements and the mirror velocity are parameters that affect the measurement speed. A resolution of 16 cm-1 and a mirror velocity of 40 mm/s results in an acquisition time of 0.05 seconds per spectrum.

‘Rapid scan’ is suitable for far-infrared (FIR), middle-infrared (MIR) and near-infrared (NIR) measurements. In the NIR, measuring range data points affect the speed of measurement.

Figure 1 shows the fast kinetics of the changes in a resin under the influence of UV light. The spectra are recorded at 50 ms intervals. Below is the corresponding signal analysis at 1,400 cm-1 and the absorption profile over time – 30 seconds in the present case. The ‘Rapid Scan’ software is therefore recommended for fast kinetics analysis within a time frame of less than one second.
