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…
A New Class of Spectrophotometers for Water Analysis.
The ONE camera to capture 16 MP images and video in all your TEM applications.
Automate sectioning and image capture of your 3D ultrastructure using serial block-face scanning electron microscopy.
Ideal for low energy surface preparation for your SEM cross section viewing.

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…
