Chromolith® HighResolution: High resolution separations without ultra high pressure. The revolutionary monolithic Chromolith® HighResolution columns are made from a single rod of high-purity monolithic silica, rather than from particles. Their unique bimodal pore structure allows the chromatographic performance to be improved significantly. Speed of analysis (separations up to 9 times faster if required) Separations two…

UHPLC columns require less solvent, but they need the highest quality there is. Merck Millipore’s LiChrosolv® solvents are optimized for UHPLC instruments. They can substantially improve the performance of your separations, particularly in combination with our proven Purospher® STAR UHPLC and Chromolith® HPLC columns. LiChrosolv® Solvents for Liquid Chromatography Benefits: Gradient grade and hypergrade qualities are suita…

The Spectroquant® analysis system includes photometers with cell tests and reagent tests which can be identified by barcodes pre-diluted standard solutions in various concentrations for increased reliability requirements residue-free cleaning agents Three-stage concept for internal controls Photometer Check - AQA 1 Easy to perform with certified color standards and/or Certipur® UV/VIS standards. System Check - AQA 2 R…

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 MAS-100 CG Ex® is the only microbial air sampler that enables you to test compressed gases in Zone 2 explosion hazard areas – safe, easy and accurate. Active air sampling is reliable and safe method for identifying microbial contamination in compressed gases. At numerous points in production compressed gases can come into contact with a product. Air sampling ensures a realistic total bioburden count.Microbial contaminatio…

Safe, Ecological, Waterproof.In order to protect the extraordinary quality of our SeccoSolv® dried solvents, we offer a fully sealed stainless steel barrel system for extremely water-sensitive applications that keeps water out even more effectively. Unlike our standard stainless steel barrels, the fully sealed barrel system requires no adapters but uses fast connectors that fit onto the rim of the barrel quickly and easily.…

This new zwitterionic stationary phase with phosphorylcholine functional group provides you with complementary selectivity for easier method development for substances that have been difficult to separate by previous types of HPLC columns operated in reversed-phase or HILIC mode. The selectivity features of SeQuant® ZIC®-cHILIC are especially beneficial for negatively charged polar compounds such as nucleotides and organic…
