Details are presented for the construction of photodiode array (PDA) measurement systems from commercial components. The PDA systems described include the Hamamatsu S2304–1024Q, a Reticon 1024S using the RC1000 and RC1001 circuit boards, and a Reticon 1024S using the RC1024S circuit board. Detals are presented for computer-controlled clocking and timing circuits, ADC sub-systems, and Peltier cooling subsystems. The measurement characteristics (sensitivity and detection limits) for all arrays are intercompared with the use of analyte emission signals from an inductively coupled plasma.
