SunArmor C18
Further Evolution of Surface Modification
Combination of novel end-capping reagent with an ethylene chain and sunniest end-capping leads a silica C18 column to be stable under pH12 condition. SunArmor C18 can be used at pH range of a mobile phase between 2 to 12. This is almost same durability to compare with a hybrid C18s column. Furthermore SunArmor C18 shows better shape for acidic, basic and metal chelating compounds than the other hybrid C18 because of little residual silanol groups.

High durability under basic pH condition
SunArmor showed almost same durability or more to compare with the other hybrid C18 columns.
 |
Duration test condition Mobile phase: Methanol/10 mM Ammonium bicarbonate (pH 10.5, Adjust with ammonia water) = 30/70 Flow: 0.8 mL/min Temperature: 60 ºC Measurement condition Mobile phase: Acetonitrile / water = 60/40 Flow: 0.2 mL/min temperature: 60 ºC Sample: Butyl benzene |
High durability under neutral pH and high temperature condition
SunArmor C18 showed much more durability under neutral pH and high temparature condition than the conventional C18 and AQ C18 columns.
 |
Duration test condition Column size: 50 x 2.1 mm Mobile phase: Methanol / 10 mM Ammonium acetate (pH 6.8) = 30/70 Flow: 0.2 mL/min temperature: 80 ºC Measurement conditions Mobile phase: Acetonitrile / water = 60/40 Flow: 0.2 mL/min temperature: 60 ºC Sample: Butyl benzene |
Sharp peak sharp in the acidic, basic and metal chelating compounds

< tR : retention time, TF : tailing factor > |
Condition (formic acid) Column dimension: 150 x 4.6 mm Mobile phase: CH3CN/0.1% H3PO4=2/98 Flow rate: 1.0 mL/min Temperature: 40 ºC Detection: UV 210 nm Sample: 1 = Formic acid 2 = Acetic acid 3 = Propionic Acid
* Hybrid C18s showed a very poor peak shape for formic acid. It is doubted that some amines as a byproduct remained on the surface of packing materials. |

< tR : retention time, TF : tailing factor > |
Condition (oxine) Column dimension: 150 x 4.6 mm Flow rate: 1.0 mL/min Temperature: 40 ºC Detection: UV 250 nm Sample: 1 = 8-Quinolinol (Oxine) 2 = Caffeine |
