In chromatography flow mode, the Zetasizer Nano permits the coupling of dynamic light scattering with size exclusion chromatography.
Prominence high-throughput HPLC systems incorporate 2.2 μm packing materials and XR series columns. The columns generate less backpressure than other sub-2 micron columns.
This line of chromatography sorbents is available for protein separation and purification for biotechnology drug discovery, development and production. The media integrate with a portfolio of membranes, protein purification technologies and services.
Jupiter Proteo 90Å-pore HPLC column from Phenomenex is offered for the analysis of peptide maps. Peptide fragments produced in a tryptic digest of a protein often exhibit significantly complex patterns, differing markedly from protein to protein.
The PS-PPh3-Pd polymer-bound resin catalyst is used for Suzuki-Miyaura coupling reactions between aryl boronic acids and aryl halides. The resin simplifies the removal of residual palladium during workup and product isolation for active pharmaceutical ingredients.
Anion and cation standards are prepared from NIST Standard Reference Materials (SRM) and certified by at least two independent methods. The method used, the exact concentration, and the NIST SRM number are provided on every certificate of analysis.
Prevail C18 is water-wettable and does not require organic solvent preconditioning; it accepts aqueous samples directly. Eliminating the organic preconditioning step reduces the use of solvents.
NycoPrep family density gradient media is prepared from Nycodenz non-ionic, non-carbohydrate media. These products offer the benefits of good cell viability, few experimental artifacts, and low endotoxin levels. The full line includes NycoPrep 1.
