What is RP column?

Updated on April 05, 2026
A reverse phase column, or reversed-phase HPLC columns, are chromatography columns that contain a non-polar stationary phase. A sample is placed into a reverse phase column and then solvent is added to flush the sample through the stationary phase.
What is Rp C18 column?
C18 columns are HPLC (high performance liquid chromatography) columns that use a C18 substance as the stationary phase. C18 simply means that the molecules contain 18 carbon atoms, so the other atoms in the molecule can vary, leading to significantly different substances.
What is l11 column?
Conventional HPLC column built to be the cornerstone for your lab; pressure rated for any 400 bar HPLC system. Solid and reliable—delivers the peak shape, reproducibility, ruggedness, and performance you demand.

What is the composition of C18 column?
YMC-Triart C18 is a multi-layer hybrid particle consisting of two types of layers: a silica based layer (inorganic) and a hybrid polymer based layer (organic). This layered structure contributes to Triart’s combined physical durability and chromatographic performance.
What is L3 packing HPLC column?
L3 USP columns are described as consisting of porous silica particles, 1.5 to 10 µm in diameter. Our L3 USP columns are produced to the highest quality standards to ensure reliable, reproducible results. A perfect example is: Purospher® STAR Si (5 µm).
What is polypolymerx™ RP-1?
PolymerX™ RP-1 consists of microporous (100 Å) polystyrene divinylbenzene (PSDVB), which is inherently similar to reversed phase chemistries, displaying similar selectivity characteristics as C18-bonded silica columns. Because bare PSDVB shows similar selectivity to a C18 column, no surface ligands are bonded to the polymer.
What is polymeric HPLC column?
Polymeric HPLC Columns. PolymerX™ RP-1 consists of microporous (100 Å) polystyrene divinylbenzene (PSDVB), which is inherently similar to reversed phase chemistries, displaying similar selectivity characteristics as C18-bonded silica columns. Because bare PSDVB shows similar selectivity to a C18 column, no surface ligands are bonded to the polymer.
What is the pH range of an rspak column?
Shodex ® RSpak ® columns are packed with porous polymeric material that are stable at a pH range of 2-12 and have a different selectivity from silica-based columns. The wide pH range makes the chromatography of basic compounds much easier because it is possible to chromatograph at a higher pH without ion-pairing slats.
