Apecialty Sorbents

Polyamide is based on Nylon 6. Due to its activation process it exhibits a constant selectivity toward flavones, chalkones, anthraquinones, aromatic nitro compounds, DNP amino acids, phenols, carbonic acids, acid amides, sulphonic acids and amides of sulphonic acids as well as towards amines and quinones. Forces which contribute to the separation involve hydrogen bonding between the nitro groups, the phenolic protons, the carboxyl groups etc. of the sample and the free amino groups of the adsorbent.

Florisil PR is a new selective adsorbent, specially processed to give consistent results when used for column cleanup and separation of chlorinated pesticide residue prior to identification and measurement of the pesticide by gas, thin layer or paper chromatography. This material is packed in Alumina Bottles to ensure purity during storage, shipment, use.
