Product Introduction

The SKC series products are excellent performance products provided by Bona Bio for HPLC, including different types of fillers and packed columns used for analysis. The SKC series chromatographic columns are classified according to chromatographic separation modes, including normal phase, reverse phase, ion exchange, hydrophobic interaction, volume exclusion, affinity, and chirality. This series of chromatographic columns has excellent solvent replaceability and durability, stable chemical and thermal properties, can withstand complex matrix analysis, excellent peak shape, high number of theoretical plate, and excellent repeatability between batches.

SKC - Normal phase chromatography column

mode	Group	Selective Features and Applications	Particle size	aperture	specifications
normal phase	silica gel	Made of high-purity silica gel, with high sample recovery rate and stable mechanical properties of porous fillers, it still has a large specific surface area at large sample loading, which can increase the resolution of sample separation	3um 5um 10um	120Å 200Å 300Å 500Å	4.6150 4.6250 10250 30250 50*250
	amino	The aminopropyl monomer is bonded onto a spherical silica gel carrier with high specific surface area, and can also be used for weak anion exchange separation
	cyan	Universal chromatographic column, providing selectivity for complementary fixation with C18. The intrinsic chromatographic column can be used for both normal phase separation and reverse phase separation.

SKC - Reversed phase chromatography column

mode	Group	Selective Features and Applications	Particle size	aperture	specifications
opposition	C18	A versatile reverse phase chromatographic column with high tolerance and stability to extreme pH conditions, as well as versatility for a wide range of compound types, has become an ideal chromatographic column for method development	3um 5um 10um	120Å 200Å 300Å 500Å	4.6150 4.6250 10250 30250 50*250
	C8	Fully sealed, with hydrophobicity lower than C18
	phenyl	Suitable as a method for developing columns that offer different selectivity, especially when it comes to aromatic compounds, as a phenyl bonded phase chromatographic column, it has unique pH tolerance compared to other phenyl column products.
	PS/DVB	The chemical properties of the polymer matrix reverse phase chromatographic column are stable in the pH range of 1-14, and can be operated under alkaline conditions. Strong acids and bases can be used for cleaning and removal of endotoxins.		100Å 300Å 500Å

SKC - ion exchange chromatography column/preparation column

mode	Group	Selective Features and Applications	Particle size	aperture	specifications
ion exchange	sulfonic acid group	A highly cross-linked cation exchange chromatographic column can be used for the separation of amino acids, amines, etc.	3um 5um 10um	100Å 300Å	4.6150 4.6250 10250 30250 50*250
	carboxyl	Cation exchange chromatographic column adopts innovative chemical bond to increase the carrying capacity and reduce the working pressure, which is suitable for the separation of proteins, monoclonal antibodies, etc.
	quaternary ammonium	Porous quaternary ammonium salt bonded polystyrene anion exchange resin allows gradient elution and is recommended for rapid analysis of physiological fluids such as urine and blood.
	Tertiary amino group	Anion exchange chromatography column can be used to separate sugars, carboxylic acids, and nucleotides.
