Sample Preparation

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

SHIMSEN Styra GCB is packed with planarized graphitized carbon, mainly used to remove pigment components from crops. The polarity and ion exchange property of this cartridge are used to purify all kinds of sample substrates. The typical application of this cartridge is the analysis of pesticide residues in agricultural products. Plant samples often contain various pigments, such as chlorophyll, lutein, carotenoids, etc, which need to be removed in order to eliminate its interference with the analysis results and experimental instruments. Retention mechanism: Surface adsorption Adsorbent: graphitized carbon with lamellar structure Particle size: 120-400 mesh   Application: Sample cleanup in pesticide residue analysis of vegetables, fruits, tea and plant products.
