Description of Echroma Series C8/C18 HPLC Columns
The Echroma series C8 and C18 HPLC columns are an economical column from Hawach with excellent peak shape and low column pressure. Selecting B-type ultra-high purity fully porous star silica gel (purity >99.999%) as the substrate, using the company’s unique new phase-bonding technology and complete sealing technology, the new generation of HPLC column products developed and introduced to the market for the majority chromatography users offer different options for method development. The series of columns is an excellent peak shape and a low column pressure, is a C18 reverse phase column. Economy column. Select type B ultra-high purity fully porous spherical silica gel (purity >99.99%) as the matrix A new generation of stationary phase bonding technology and complete tailing technology, developed and marketed to the next generation of HPLC column products provide a wide range of options for the development of methodologies for a wide range of column users. C8 has a slightly smaller column than C18.
