Markets Served
WITec products are delivered worldwide to academic and industrial research labs focusing on high-resolution chemical imaging and materials characterization. Areas of application for WITec's confocal Raman imaging systems include polymer sciences, pharmaceutics, life science, geoscience, thin films and coating analysis, semiconductors, and nanotechnology.
Major Products/Services
WITec alpha300 Confocal Raman Microscope: The alpha300 R is a Raman imaging system focusing on high-resolution as well as high-speed spectra and image acquisition. The acquisition time for a single Raman spectrum is in the range of 1 ms or even below; thus, a complete Raman image consisting of tens of thousands of spectra can be obtained in 1 min or less. Differences in chemical composition, although completely invisible in the optical image, will be apparent in the Raman image and can be analyzed with a resolution down to 200 nm.
WITec alpha500 Automated Confocal Raman & Atomic Force Microscope: The alpha500 is an automated confocal Raman and atomic force microscopy system incorporating a motorized sample stage for large samples and customized multi-area/multi-point measurements. It allows nondestructive chemical imaging with confocal Raman microscopy as well as high-resolution topography imaging with AFM using the integrated piezo scan-stage. Both modes can be run fully automatically, guaranteeing the most comprehensive surface inspection possibilities for systematic and routine research tasks or high-level quality control.

This column shows that a Raman plate reader paired with partial least squares regression can simultaneously quantify glucose, fructose, sucrose, and ethanol in yeast fermentation samples, using turbidity-matched calibration standards to correct for yeast-induced turbidity, and offers a rapid, label-free, high-throughput method for tracking sugar consumption and ethanol production in strain screening, media optimization, and process development.
This column, the second installment on highly substituted benzene rings, shows that tri- and tetra-substituted substitution patterns can be distinguished by whether the ring bending peak is present and by the position of the in-phase aryl C-H wagging peak, which shifts according to how many adjacent hydrogens the ring carries.
