Sample Preparation

SHIMSEN Styra AL-N is packed with neutral alumina (Al2O3) to retain or remove polar compounds. Similar to silica gel, neutral Al2O3 is a strongly polar sorbent. However, the neutral alumina tends to be slightly more stable under high pH conditions than silica gel. The neutralized surface allows interaction with compounds whose heteroatoms are electronegative (e.g., O, P, S) or with an electron-rich, highly aromatic structure. Retention mechanism: Lewis acid-base interaction, polar interaction and ion exchange interaction Adsorbent: Neutral AI2O3 particles with size of 125 μm pH ：7.5   Application: SHIMSEN Styra AL-N is used to extract polar or non-polar compounds from both aqueous and non-aqueous solutions, such as sample preparation of malachite green and crystal violet in aquatic products.

SHIMSEN Styra AL-A is packed with acidic alumina (Al2O3) to retain or remove polar compounds and acidic compounds. Acidic alumina is a typical Lewis acid with two electrons missing from the aluminum atom. Acid treatment enhances the Lewis acid property of alumina, and results in a weak cationic property, allowing strong interaction with electron-rich compounds and retention of polar compounds and anionic compounds. Retention mechanism: Lewis acid-base interaction, polar interaction and ion exchange interaction Adsorbent: Acidic AI2O3 particles with size of 125 μm pH ：4.5   Application: Retention of polar compounds and anionic compounds.   Part Number Specification Pack size 380-00867-01 500 mg / 6mL 30 380-00867-02 500 mg / 3 mL 50 380-00867-03 5 g / 20 mL 20 380-00867-04 2 g / 12 mL 20 380-00867-05 1000 mg / 6 mL 30 380-00867-06 100 mg / 1 mL 100 380-00867-07 10 g / 60 mL 10
