Uvasol® solvents from Merck Millipore are specially designed for spectroscopy and other applications that demand solvents of the highest purity. By avoiding trace contamination, they prevent misinterpretation of your results caused by traces of ultraviolet (UV), infrared (IR) and fluorescence active contamination and eliminate the need for repeat analyses.  Accurate analytical results and minimal risk of misinterpretation d…

ZIC®-HILIC HPLC columns for the separation of all classes of polar and hydrophilic compounds. What is HILIC? HILIC or Hydrophilic Interaction Liquid Chromatography is a straightforward chromatographic technique for separation of many types of polar and hydrophilic compounds. To put it simple one can say that HILIC is a normal-phase (NPLC) type of separation but uses reversed-phase (RPLC) type eluents. In HILIC one has: A c…

The base silica of Purospher® STAR columns is 99.999 % pure. Furthermore, meticulous care is given to quality control over all aspects of silica structure and chemistry. The excellent converge of the surface and the purity of the material ensures excellent peak symmetry for acidic, basic and even for chelating compounds. Accurate results with excellent peak shape for all types of analytes Outstanding resolution due…

High purity solvents for LC-MS and trace analysis with UV and fluorescence detection: 0.2 µm stainless steel filtered – perfect for use in UPLC and UHPLC. Very high UV-transmittance. Excellent baseline stability in gradient elution. Very low total ionic current (TIC) in LC-MS. Low level of ionic background and ion suppression. High ionization efficiency in all ionization methods (electrospray ionization/atmospher…

The WITec alpha300 R leads the industry in speed, sensitivity and resolution. 

True Surface Microscopy - Confocal Microscopy Along with Large Area Optical Profiling WITec´s new True Surface Microscopy option (patent pending) allows confocal Raman imaging guided by surface topography. Confocal microscopy is often desirable due to its suppression of out-of-focus light but can be challenging when analyzing large or rough surfaces. In these cases, only those points that are in focus contribute to the image.…

Scanning Probe Microscope Series WITec alpha300 The WITec microscopy series features scanning probe as well as high resolution optical and Raman microscopy techniques in either a single instrument or combined system configurations for the highest flexibility throughout a wide range of microscopy applications. For example, it is possible to start with Confocal Raman Microscopy and upgrade later to Atomic Force Microscopy or vic…
