Say goodbye to the limitations of traditional columns. Break free from the constraints of your Liquid Chromatography instrument. With Brownlee Superficially Porous Particle (SPP) columns, you can achieve sharper peaks and faster separation results without changing instruments, worrying about high backpressure or compromising column longevity.

With their unique particle composition, only Brownlee SPP columns offer you the freedom to push your process farther.

Excellent phase for significantly increasing the retention and selectivity of acids, for symmetrical peak shapes of bases, zwitterions and other polar compounds. A base-deactivated phase with a polar group within thealkyl bonded phase. Provides unique selectivity and a high level of base deactivation while reducing or eliminating the need for mobile phase additives.
