COSMOSIL 5C18-AR-II

The COSMOSIL 5C18-AR-II packed column feature a polymeric and near-perfectly end-capped type of C18 reversed phase material that employs an ultra-pure silica gel low in metal impurities. The highly acidic resistance COSMOSIL 5C18-AR-II column is especially effective for the separation of chelating compounds as well as both acidic and basic compounds. This series of columns is also highly recommend for a wide range of applications particularly in situations where monomeric-type columns (i.e. COSMOSIL 5 C18-MS) is not as effective.

MATERIAL CHARACTERISTICS
 
COSMOSIL 5C18-AR-II

Silica gel

totally porous spherical silica gel

Average particle size

5 µm

Average Pore size

approx. 120 Å

Specific surface area

approx. 300m2/g

Stationary phase

polymeric type octadecyl group

Carbon content

approx. 17%


ACIDIC RESISTANCE

BASIC PERFORMANCE

There is no difference in the separation patterns between the COSMOSIL 5C18-AR-II and COSMOSIL 5 C18-MS. It proves that the combining volume between silica gel and ODS in both packing material is almost the same.

SEPARATION OF CHELATING, ACIDIC, BASIC COMPOUNDS

The COSMOSIL 5C18-AR-II employs ultra pure silica gel low in metal impurities. Thus, chelating compounds such as Hinokitiol and Oxine-copper are separated sharply as shown in the chromatograms below.
