Using a robust design, highly sensitive array detectors with permanent wavelength calibration, and minimal maintenance requirements make array-based, online spectroscopic instrumentation the ideal solution for many process applications.
The speed of analysis in process is critical and array systems are capable of generating actionable results in milliseconds. A typical scanning based UV/VIS/NIR system could require a minute or more for the same measurement information.
- Blend uniformity and concentration validation
- Incoming raw material inspection
- Fast kinetics
- Dissolution testing
- Moisture concentration
- Final product verification
- Cleaning validation
The measurement of the concentration of various solutes in liquid solutions is a well-known and widely used measurement technique in chemistry, pharmacy, petro-chemistry, and many other fields. Solute materials may interact with light over a wide spectral range, from the deep UV to the IR. Beer’s Law is used to define the absorption of the light passing through a sample of fixed path length, thus the measurement of light transmitted through a liquid allows not only the identification of the chemical content but also a quantification of the concentration.
