Simple cross injector

FIGURE 15.7 Subsecond chiral separation of DNS-norleucine achieved using a simple cross-injector quartz microchip. The separation was performed in a 1.5-mm-long channel, using an electric field of 2012 V cm and 1% highly sulfated y-cyclodexlrin, 25 mM triethylammonium phosphate buffer, pH 2.5, as the separation buffer. (Reproduced from Piehl, et al. Electrophoresis 25, 3848, 2004.)... [Pg.459]

Various injector geometries (simple cross, double-T, triple-T) were investigated on a glass microchip. The triple-T injector allowed for a selection of different injection volumes. For instance, a triple-T injector allowed injection of three different volumes depending on whether a cross, double-T, or triple-T configuration was used (see Figure 4.6) [529]. Pinched injection has been used consecutively to inject two samples into the same separation channel (see Figure 4.7) [557]. [Pg.108]

The typical layout of a microchip electrophoresis (both a simple cross T-injector (A), and a twin-T injector (B)) has been already depicted in Fig. 21.5. It has a network of channels with widths varying from 10 to 100 pm with typical straight separation channels between 3 and 10 cm. In a typical set-up, buffer solutions are introduced on sample (S), running buffer (RB), and waste (W) reservoirs. The... [Pg.634]
