| COLUMN CHROMATOGRAPHY & TLC SORBENTS |
The superior quality, reproducible sorbents suit any performance requirements. Bulk density 0.35g/mL for <40µm particle size. Bulk density 0.5g/mL for 40–500µm particle size. Extra pure silica gel (7754-1, 7754-3) is acid washed and contains <0.0005% lead, <0.002% iron, <0.0005% copper, <0.0005% cadmium, <0.0005% zinc, <0.008% chloride, <0.0005% phosphate, <0.003% sulfate, and <0.004% nitrate. Geduran* gel is an economical alternative to 9385-3, 9385-4, 9385-5, 9385-9, 7734-3, 7734-4, and 7734-7.
Key to code letters/numbers in column 1 of price table: Activity refers to Brockmann activity. Relative activity is directly related to the water content of the sorbent, most active being I and thereafter decreasing to the least active III.
NOTICE: Aluminum oxide chromatography sorbents will adsorb water from the air. It must be stored in air-tight containers or its Brockmann activity can change.
