日本住友化学 SUMICHIRAL色谱柱 OA-SHELL P1
Core-shell type chiral stationary phase
SUMICHIRALTM OA-SHELL P1
SUMICHIRALTM OA-SHELL P1 is our first chiral stationary phase using optical active polymer. It is effective for chiral separation of compounds without amino group or carboxyl group，which are generally difficult to separate with conventional chiral stationary phases. Especially, it shows excellent resolution for aromatic chiral alcohol compounds. Core‐shell silica is used as a support and coated with poly (diphenylacetylene) derivative (optically active spiral polymer).
【Advantages of SUMICHIRALTM OA-SHELL P1】
Chiral stationary phase using core-shell silica support
★ Analysis time could be shortened with conventional HPLC ★
- Effective for chiral separation of compounds without amino group or carboxyl group ★
- Easy method development with simple mobile phase compositions ★
- Excellent durability, lot-to-lot repeatability ★
Unlike full porous particles, the core-shell particle has a non-porous core in the center and a thin porous layer outside of the core.
【Method development 】
SUMICHIRALTM OA-SHELL P1 makes it easy to set the conditions of mobile phase. The scheme of the general method development is shown in the right figure. For neutral compounds such as aromatic alcohols, it is not usually necessary to add special modifiers. For acidic compounds, add trifluoroacetic acid.
- Do not use the following solvents as they will cause the column to deteriorate : tetrahydrofuran, 1,2-dichloroethane, chloroform, ethyl acetate, acetone, etc.
Standard mobile phase n-hexane/2-propanol（95/5）
Change the concentration of 2 -propanol and adjust the retention time
（concentration of 2-propanol 0～20％）
Change 2-propanol to ethanol
（concentration of ethanol 0～10％）
For acidic compounds etc., add trifluoroacetic acid
|【Durability test】||（concentration of trifluoroacetic acid||0.02～0.1％）|
SUMICHIRALTM OA-SHELL P1 has excellent durability despite the use of optically active polymers as chiral selectors. The mobile phase was continuously fed to the column, and the stability was evaluated under the following conditions. As a result, almost no change was observed in separation factor, resolution, retention time, and column pressure.
mobile phase：n-hexane / ethanol（95/5）
flow rate：0.2 ｍL/min detection：UV254 nm
