Indeed, we are the official sole distributor of Alltima & Alltima HP columns in Switzerland. We are a technical company that offers fast and uncomplicated service and delivery lead times.
The Alltima HPLC column range
Was originally developed by Alltech.
Hichrom acquired the entire range from Grace. 2015 Hichrom was acquired by VWR. By 2017 Antor acqiured VWR.
Alltima phases are acid and base-deactivated, giving excellent peak shape for acids, bases, and
neutrals in a single run.
Polymerically bonded and double-endcapped for long column lifetimes,
Alltima columns are great general purpose “workhorse” columns.
- Base deactivated silica
- Stable bonding for long column lifetime
- Symmetrical peak shape
Alltima HP HPLC Columns
The Alltima HP range of HPLC columns was developed by Alltech.
Hichrom acquired this range from Grace. 2015 Hichrom was acquired by VWR. 2017 Antor acquired VWR.
Alltima HP columns offer a range of different phase chemistries based on high purity silica.
The Alltima HP product family combines the selectivity and performance needed to
overcome the most challenging separation needs.
The low column bleed makes these columns ideal for microbore applications.
- High purity silica
- Excellent column stability
- Low to no detectable column bleed
- pH stability from 1 to 10
- Multiple selectivity options
Alltima HP Phase Specification
|Phase||Particle Size||Endcapped||Properties||Application||USP Code|
|C18|| 3, 5||Yes||Classic reversed-phase retention and selectivity||Routine applications||L1|
|C18 EPS||3, 5||Yes||Greater retention and enhanced peak|
symmetry for polar compounds. Alternative
selectivity to traditional reversed-phase
|Reversed-phase applications where C18 is too|
|C18 High Load||3, 5||Yes||Highest carbon load for superior retention and|
|High resolution for complex samples||L1|
|C18 AQ||3, 5||Yes||100% water wettable||Applications requiring high aqueous mobile phases||L1|
|C18 Amide||3, 5||Yes||Polar-embedded phase with extremely low|
bleed. Compatible with microbore
|Basic compounds in neutral to alkaline pH, MS|
|C8||3, 5||Yes||Lower retention compared to C18 phases||Reversed-phase applications where C18 is too|

|Silica||3, 5||No||Highly polar phase||General purpose normal phase applications||L3|
|HILIC||3, 5||Hydrophilic Interaction Chromatography uses|
small amounts of water for increased sensitivity
with microbore applications
|Very polar analytes that are difficult to retain by|
