Place your order directly with the manufacturer.
The XSelect Premier Peptide HSS T3 Columns are designed for separations where silica-based selectivities are desired or when increased retention of hydrophilic peptides are required.
Expand your detection range with a detector purposefully built for Empower Software
Delivering up to 4× faster runs with half the sample, the omniDAWN™ multi-angle static light scattering (MALS) photometer is purpose-built for UPLC™ and UHPLC systems for non-destructive absolute molar mass and size characterization of macromolecules and nanoparticles in solution.
Run samples and produce meaningful results without downtime with Empower Software Solutions, comprised of Waters industry-leading Empower Chromatography Data System (CDS) and Empower Lab Management System (LMS).
The patented RapiGest™ SF Surfactant is a reagent used to enhance enzymatic digestion of proteins, both in-gel and in-solution. RapiGest SF helps solubilize proteins, making them more susceptible to enzymatic cleavage without inhibiting enzyme activity.Unlike other commonly used denaturants, such as SDS or urea, RapiGest SF does not modify peptides or suppress protease activity. It is compatible with enzymes such as Trypsin, Lys-C, Asp-N, Glu-C, PNGaseF and other enzymes.Compatible for LC and MS analysisImproves efficiency and speed of digestionDegraded at low pH and removed from the sampleSimplifies preparation protocols and improves throughput of analysisUS Patent No: 7,229,539 and US 8,580,533
Most chromatographers have experienced problems retaining and separating polar compounds using conventional reversed-phase chromatography. These difficult-to-analyze compounds either pass through the column unretained or, if retained at all, co-elute at the beginning of the chromatogram. Waters AtlantisTM columns are designed for these types of challenging separations and are available in two chemistries: dC18 and HILIC silica. AtlantisTM dC18 columns are a fully LC/MS compatible line of difunctionally bonded C18 columns that exhibit superior retention of polar compounds under reversed-phase conditions. AtlantisTM HILIC silica columns are designed for high throughput LC/MS applications where the high organic mobile phase conditions used in hydrophilic interaction chromatography (HILIC) are desired. The use of HILIC mobile phases yields improved LC/ESI-MS response, direct compatibility with SPE solvents and complementary selectivity as compared to reversed-phase HPLC. New Atlantis™ Intelligent Speed (IS) columns are powerful tools for the LC/MS scientist who is looking for faster methods and increased sample throughput.
LC/GC Certified vials are tested by LC/UV for residues of chemicals used in processing and packaging vials. The septa are tested by headspace GC to ensure low levels of low molecular weight polymer. These vials are suited for analyte concentration in the µg/mL concentration; typically detectors like UV and RI.
