QUICKSORB
QUICKSORB (18 nm pore, 200 m2/g, 13% carbon), is suitable for high throughput HPLC separation. It reduces the actual analysis time in isocratic elution. In spite of shorter analysis time, the chromatographic performance is still maintained. In addition, the ultimate end capping and pure silica gel enable excellent peak shape for basic and/ or chelating samples.

CHEMCOBOND
CHEMCOBOND series packings are prepared from ultra pure silica gel that is obtained by sol-gel technology. Due to its narrow particle size distribution. CHEMCOBOND series give lower column back pressure than CHEMCOSORB. Peak shape for basic and chelateing solute are improved because of excellent endcaping
and metal free silica gel.

CHEMCOSORB
CHEMCOSORB, completely porous silica packings, is prepared from M. Nagel’s Nucleosil 8, 10 and 12 nm silica gel with our unique surface modification. Wide pore packings are also available for peptide and protein separation. All of packings are processed our careful end-capping treatment and give good peak shape for basic solute.

CHEMCOSORB U-series
CHEMCOSORB U-series packings are prepared from special silica with extremely large surface area (6nm pore, 600 m2/g). With this property of base material and our modification process, CHEMCOSORB U-series results in more retentive and unique phase than other bland column. Wide range of chemical phase, ODS, C8, Diphenyl, TMS, CN, NH2 and Si are available.
