High Performance UNIPLATES provide high resolution separations in less than five minutes with migration distances as little as 5 to 7 cm. These plates are prepared with high efficiency silica gel having a 10 micron average particle diameter and narrow particle size distribution. The adosrbent layers are only 150 microns thick, resulting in a more rapid solvent migration. The adsorbent capacity is more than adequate for small samples used in high performance TLC techniques. Typically, sample volumes for high performance TLC are less than one microliter. Samples spots are normally smaller than one millimeter in diameter. Samples are spotted 1.0 to 1.5 cm from the bottom edge of the plate and 0.3 to 0.5 cm apart. Since smaller samples are applied, one 10 x 10 cm plate can separate as many samples as can be separated on a 20 x 20 cm plate using standard TLC techinques. The smooth homogeneous surface of HPTLC UNIPLATES gives high signal-to-noise ratios for densitometric scanning, this increasing sensitivity and precision.
