Separations is a fundamental scientific discipline focused on the isolation and purification of components from mixtures. Through techniques such as chromatography, distillation, and filtration, separations scientists separate substances based on their physical or chemical properties. This field plays a crucial role in various industries, including pharmaceuticals, food and beverage testing, environmental science, materials research, and more. Explore how separations techniques enable precise analysis, quality control, and the development of innovative products.
Dispersive SPE (dSPE), often referred to as the "QuEChERS" method (Quick, Easy, Cheap, Effective, Rugged, and Safe), is modern sample prep technique that is becoming increasingly popular in the area of multi-residue pesticide analysis in food and agricultural products. Using the QuEChERS method, food/agricultural samples are first extracted with an aqueous miscible solvent (e.g., acetonitrile) in the presence of high amoun…
Introducing the Supel-Select SCX SPE Tube from Sigma Aldrich
The SilverQuest™ Silver Staining Kit provides a rapid and easy method to silver stain proteins and DNA in polyacrylamide gels. Silver staining allows detection of most proteins since it is 30-fold more sensitive than staining with colloidal Coomassie® G-250. The SilverQuest™ Silver Staining Kit is specifically designed to provide sensitive silver staining compatible with mass spectrometry analysis. Ideal for rapid preparati…
To successfully separate trityl-off, deprotected oligonucleotides, you need columns that have high resolving power and are robust enough to withstand challenging conditions.
Synthetic chemistry is seen by some students as a complicated issue. How about changing the perspective? What about simplifying the work of students, teachers and chemists in general?
Detection to trace levels of some metabolites, such as histamine, some amino acids, some steroids and catecholamines, is quickly and simply achieved, with Cecil Electrochemical Detection Adept HPLC.
Stainless steel fittings remain the most popular fitting used on standard HPLC systems today, due to their high temperature resistance and high-pressure holding abilities. Our durable and strong 316 Stainless Steel Fittings are rated to 20,000 psi (1,380 bar) when wrench tightened. You can choose our Standard Fittings, or select from other manufacturer-compatible offerings.
MX Series II™ actuated valves are designed to be added to your existing instrument or to work optimally with stand-alone lab configurations. Our valves can be controlled remotely or operated manually using the push-button front panel with LED position indicator. They easily connect to your instrument or PC through contact closure, BCD, serial port, or USB. Commands can be sent to the MX valves using your chromatograph…
We offer an innovative line of Very High Pressure (VHP) fittings, designed to withstand extreme pressures. This patent-pending line of ground-breaking fitting systems is perfect for use within the increasingly demanding requirements of today’s UHPLC high performance analytical systems.
Precise, high-speed elemental analysis for process control in metal production
The Ascentis Express biphenyl phase chemistry offers alternative selectivity for pharmaceutical analytes and drug metabolites that are not well retained or difficult to resolve on traditional alkyl (C18) and phenyl bonded phases. Ascentis Express HPLC columns, through the use of Fused-Core® particle technology, can provide you with both the high speed and high efficiencies of sub-2 ?m particles while maintaining lower backp…
