Single or multi-component analysis and concentration measurement.

Tec5 is a leading supplier of industrial fiber optic UV-VIS-NIR spectrometer systems for analyzing solutions in industrial processes and in the laboratory. Process spectrometers are based on Diode Array detector technology (PDA) and uses Tec5’s new MultiSpec®Pro software.

Lisco Analytical partners with Tec5 on projects and support, and uses their technology to solve specific applications.

Real time in-line measurement and recording of spectra provides information about the process medium composition, concentration, and other chemical parameters in liquids and gases. Process spectrometers provide a “fingerprint of the process,” which is used for monitoring and controlling the process, trace analysis, quality control, environmental control, etc.

Process Analytical Technology (PAT)

Pharmaceutical production uses spectroscopic techniques in the implementation of PAT (Process Analytical Technology). The measurement of critical process parameters with in-line spectrometers helps to ensure optimal process monitoring and safety in production units, which leads to reduced production costs, improved product quality, and improved safety in the production environment.

Delivery Program

  • MultiSpec® UV-VIS-NIR Systems
  • MultiSpec® Raman Spectrometer System

Spectrometers

CompactSpec® II is a fast and robust UV-VIS-NIR spectrometer system in a cabinet of stainless steel (IP54) with an integrated PC and TFT touch screen. The system is available with different spectral ranges and wavelength resolution. The integrated spectrometer modules are high performance long-term stable optical components from Carl Zeiss, which have high reliability and no moving parts. Fast and robust multiplexer technology allows for the measurement of up to 8 channels without losing speed and stability. A separate reference channel guarantees drift free measurements. Fiber optics combined with insertion probes and flow cells allow for direct measurement in pipes or reaction vessels. By default, the Compact Spec® II is equipped with a vortex cooling device to withstand the high temperatures of the surrounding enviornment.

CompactSpec® II EExp is a pressurized EEx-version for mounting in hazardous production areas. This means that it can use short optical fiber cables to prevent loss of light by attenuation.
