SunArmor

Product Description

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. Although Sunniest end-capping leaded to stability under pH10 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.

Technical specifications

High durability under basic pH condition

Duration test condition

• Column size: 50 x 2.1 mm
• 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

SunArmor showed almost same durability or more to compare with the other hybrid C18.

 

High durability in a neutral and high temperature conditions

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

SunArmor C18 showed much more durability under neutral pH and high temparature condition than the conventional C18 and AQ C18.
