Silicone based SPE Bond Elut SI (Polar Positive Phase Silicone Column)
Positive phase adsorbents are polar and used to retain (extract) polar analytes. For positive phase adsorbents, the retention decreases with increasin
Product details
*Highly polar stationary phase, retaining polar molecules from non-polar matrix
*High purity silicone gel
*Compounds with very similar separation structures
It is generally believed that natural silicone is the most polar material currently availableSPE adsorbent. Bond Elut SI is particularly suitable for separating compounds with very similar structures. Dissolve the analyte in a non-polar solvent, and then increase the concentration of polar modifier (such as THF or ethyl acetate) to increase the polarity of the solute, which can achieve effective separation
