Description of C8/C18 Reverse Phase HPLC Columns

Hawach Scientific EChroma HPLC Columns with type B ultra-high purity full porous spherical silica gel (purity > 99.999%) as the matrix, have an extremely good peak shape and the economy of low-pressure chroma to the graphic column. The packing is the sorbent with C8 and C18 column in HPLC.

For non-polar samples (such as small molecule aromatic hydrocarbons) or weakly polar samples (such as parabens), C18 and C8 HPLC columns are the easiest choices. What is the difference between c8 and c18 column? For this type of sample, the main difference between the C8 C18 HPLC columns is the retention ability and polarity. However, there is only a slight difference in selectivity. C8 and C18 column in HPLC is quite difficult to choose a column for polar and mid-polarity samples. For example, pharmaceutical compounds containing amino or acidic groups.
