General purpose columns for FAMEs, flavor compounds, essential oils, solvents, xylene isomers, and US EPA Method 603 (acrolein/acrylonitrile). Resistant to oxidative damage. Temperature range: 40°C to 260°C. Equivalent to USP G14, G15, G16, G20, and G39 phases. The polar-deactivated surface tightly binds the Carbowax® polymer and increases thermal stability, relative to competitive columns. The bonding mechanisms produce a col…

With Raptor™ LC columns, Restek chemists became the first to combine the speed of superficially porous particles (also known as SPP or “core-shell” particles) with the resolution of highly selective USLC® technology. This new breed of chromatographic column allows you to more easily achieve peak separation and faster analysis times without expensive UHPLC instrumentation. SPP core-shell columns commonly employ traditional phe…

Separate a wide variety of polar analytes with a novel hybrid stationary phase

The mixer mill MM 400 is a compact versatile bench-top unit, which has been developed specially for dry, wet and cryogenic grinding of small amounts of sample.

The basis for quality and reproducibility of the analysis

The key to reproducible results by development under standardized conditions

High-end imaging and documentation system for white light and UV fluorescence detection

Application of up to 75 samples as bands onto HPTLC glass plates (20 x 10 cm).

The visionCATS software organizes the workflow of the HPTLC analysis, controls the CAMAG instruments, and manages data evaluation.

The TLC-MS Interface 2 enables users to directly analyze zones from TLC and HPTLC plates by mass spectrometry. A substance confirmation can be obtained in less than a minute.

The TLC Scanner 4 is the most advanced workstation for densitometric evaluation of TLC/HPTLC chromatograms and other planar objects.

ZipChip enables seamless CE/ESI-MS workflow and provides fast CE separation, nano-spray level sensitivity to obtain high-resolution separation and mass spec data from characterization of intact proteins, antibody drug conjugates (ADCs), antibody subunits, peptides, and nucleic acids.

The 1515 Isocratic HPLC Pump is an isocratic pump that offers the same performance as the 1525 Binary HPLC Pump. It features and integrated, high-pressure binary pump with on-board pulse dampening and efficient mixing. Its pulse-free solvent flow with analytical to semi-preparative flow rates are well suited for high sensitivity detectors Designed for use with 2 to 4.6 mm I.D. columns in routine HPLC applications, the pump has…

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,…

Protein/Peptide Columns

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.

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 sili…
