Cleanert (R) Florisil Solid Phase Extraction Column

Product Description: How to Translate

Cleanert Florisil is a highly selective adsorbent. This adsorbent mainly consists of three components: silica (84%), magnesium oxide (15.5%), and sodium sulfate (0.5%). It is a commonly used solid-phase extraction filler with good performance and cost-effectiveness. Specifically designed for AOAC, EPA and other methods, it is used for the purification, separation, internal secretion and oil separation of pesticide residues PCBs，PAHs， Separation of nitrogen-containing compounds and antibiotic substances in hydrocarbons. Commonly used for removing pigments in pesticide residue analysis, it is an essential sample precursor in the NY761 analysis method

Product Parameters:

Average particle size: 60-100 mesh

Average pore size: 80 A; Specific surface area: 290 m2/g;

Recommended operating procedures for pesticide residue detection in fruits and vegetables:

Conditionalize the Cleanert Florisil (1000 mg/6 mL, Cat. No. FS0006) column with 5.0 mL of acetone+n-hexane (10%+90%) and 5.0 mL of n-hexane in sequence. When the solvent level reaches the surface of the column adsorption layer, immediately pour in the sample solution, receive the eluent in a 15 mL graduated centrifuge tube, rinse the beaker with 5 mL of acetone+n-hexane (10%+90%), rinse the Florisil column, and repeat once. Place the centrifuge tube containing the eluent on a nitrogen blower, and under the condition of a water bath temperature of 50 ℃, evaporate the nitrogen to less than 5 mL. Use n-hexane to accurately determine the volume to 5.0 mL. Mix well on a vortex mixer and transfer into two 2 mL automatic sampler sample bottles for testing.
