Lux™ Cellulose-1 and -2, complementary chiral stationary phases, are now available in 10-micron particle size for batch-preparative chromatography. The 10-micron particles are available both in Axia™-packed preparative columns, and in bulk, enabling customers to pack their own columns for purification methods. Lux chiral phases Cellulose-1, -2, -3, and -4 are already offered in 20-micron bulk media for use in batch-preparative and simulated moving-bed chromatography.
