Supelco - Supel Sphere Carbon/NH2 SPE Tubes
FromSigma-Aldrich
The demand for SPE cartridges with improved flow characteristics and reduced susceptibility to the formation of fines has led to the development of a family of SPE tubes packed entirely with spherical, non-friable particles. The Supel Sphere Carbon/NH2 dual layer SPE tube contains both spherical carbon particles and spherical aminopropyl (NH2) modified silica . It was developed to offer superior flow characteristics when conducting cleanup for multi-residue pesticide analysis from food.
