Analytical HPLC expertise
At EMD Millipore, we use analytical HPLC everyday for high throughput analysis, method development, process monitoring and QC to deliver the consistently high quality products you rely on. By staying on the cutting edge of chromatography technology, we’ve gained a lot of experience in both product and method development. We’re committed to supporting your success by sharing that expertise.
Comprehensive USP methods compilation – just a click away
Our chromatography experts have compiled an extensive collection of analytical HPLC application notes and methods. Of special importance are the new methods for commercially successful pharmaceutical molecules we’ve developed according to USP (United States Pharmacopeia) guidelines and regulations. Using these USP methods, in combination with EMD Millipore’s HPLC columns and high purity solvents, one can quickly establish reliable QC processes for pharmaceuticals. Whether you’re developing new methods or optimizing existing processes, you can take advantage of this wealth of information. Just visit the EMD Millipore website and click on ‘Application Finder’.
Universal column delivers outstanding separation performance
Purospher® STAR RP-18 endcapped HPLC columns are made from high purity, metal-free silica. A special derivatization and endcapping process ensures best over-all chromatographic properties of the column and excellent symmetrical peaks. Purospher® STAR RP-18 endcapped HPLC columns deliver outstanding performance in almost all common HPLC applications, including LC/MS.
Methods can be developed over a wide pH range from pH 1.5 – 10.5. Suitability for use with 100% aqueous mobile phases gives high flexibility in choosing eluent conditions.
Whether analyzing neutral, acidic, basic or chelating compounds, one column produces the best results. Flexibility, sensitivity and highest reproducibility make Purospher® STAR RP-18 endcapped HPLC columns the ideal choice for method development.
Easy method development
One column type delivers excellent results for most applications.
High purity silica particles
Superior separation and excellent peak symmetry for reliably accurate results.
Extraordinary pH stability from pH 1.5 – 10.5
For an extremely wide application range.
Compatible with 100% aqueous mobile phases
Well-suited to a range of eluent conditions without phase collapse.
Outstanding batch-to-batch reproducibility.
HPLC solvents in application specific quality grades
High-purity OmniSolv® Solvents eliminate misinterpretation of analytical results commonly seen with inferior quality HPLC solvents. OmniSolv® Solvents are available in different grades optimized for specific HPLC methods. Low UV absorbance, low particle count, low evaporation residue level, combined with low acidity and alkalinity make OmniSolv® solvents especially well-suited for reliable, high resolution separations using isocratic or gradient elution.
LC-MS OmniSolv® solvents are designed to meet the requirements for LC-MS ionization methods with low ion suppression, low level of ionic background and high ionization efficiency.
From standard sizes to EMD ReCycler® returnable stainless steel containers, our innovative packaging safeguards the quality of OmniSolv® Solvents. A broad range of dispensing systems provides you flexibility and eliminates the risk of solvent contamination during use. EMD Millipore also offers custom packaging tailored specifically to your needs.
Less time spent analyzing and investigating peaks that you may have to report in your product analysis.
Reduced baseline drift
Avoids peak misinterpretation and repetition of analysis.
Application oriented specifications
Solvent quality matches HPLC application for superior performance.
Outstanding batch-to-batch consistency
Highest reproducibility of final results.
Flexibility in packaging and dispensing systems
Available in package sizes from 1 L to 1250 L, custom packaging also available.
