Diode array detector location

Fast chiral separations were carried out in a quartz chip using a linear imaging UV detector. Figure 6.11 shows the chiral separation of a tocainide derivative (an antiarrhythmic drug). UV imaging with a diode-array detector located along the 25-mm-long separation channel reveals the separation between the two enantiomers. Another chiral separation of pseudoephedrine was achieved in 13 s. The... [Pg.148]

A photocell or other detector determines the intensity of transmitted radiation. In a single-beam instrument, the cell containing the sample substance and a blank cell not containing this substance are placed alternately in the beam. In a double-beam instrument, the beam is divided and passed simultaneously through the sample cell and the blank cell. In a diode-array instrument, a number of detectors in different locations are used, and the entire spectrum is taken at one time. [Pg.956]
