GC liners - Hints and tips - Chromatography /
GC liners For most chromatographers poor sample reproducibility and mass transfer onto chromatographic column are generally the most critical issues in the method developement. Among others poor reproducibility and mass transfer can be caused by the degradation of the compounds by the glass inlet liner or by means of insufficient vaporization.

Luna HPLC Columns - Phenomenex UHPLC, HPLC, SPE,
Luna C18(2) phase is an octadecyl silane with ligands bound to the silica surface,resulting in a C18 HPLC column with very hydrophobic stationary phase that offers great methylene selectivity. The non-polar endcapping of the Luna C18(2) column phase virtually eliminates silanol interactions resulting in a reversed phase HPLC column that can be used for USP methods or general LC
