“…This detector, called a segmented array charge-coupled device detector (SCD), employs over 200 small subarrays of 20-80 pixels each. (41) The subarrays are positioned along the two-dimensional focal plane of an echelle polychromator. The position of each subarray corresponds to one of the 236 most prominent ICP emission lines of the most commonly determined 70 ICP elements.…”

Inductively coupled plasma/optical emission spectrometry (ICP/OES) is a powerful tool for the determination of metals in a variety of different sample matrices. With this technique, liquid samples are injected into a radiofrequency (RF)-induced argon plasma using one of a variety of nebulizers or sample introduction techniques.The sample mist reaching the plasma is quickly dried, vaporized, and energized through collisional excitation at high temperature. The atomic emission emanating from the plasma is viewed in either a radial or axial configuration, collected with a lens or mirror, and imaged onto the entrance slit of a wavelength selection device. Single element measurements can be performed costeffectively with a simple monochromator/photomultiplier tube (PMT) combination, and simultaneous multielement determinations are performed for up to 70 elements with the combination of a polychromator and an array detector. The analytical performance of such systems is competitive with most other inorganic analysis techniques, especially with regards to sample throughput and sensitivity.

As a tool for screening large numbers of biological samples by means of amplification ͑e.g., Q␤ or PCR͒ we have constructed a thermocycler that includes optionally a 96-channel or 960-channel glass fiber fluorimeter ͑combined with a cooled charge-coupled-device camera͒. We briefly describe the system integration of all components like liquid handling, thermostats, an x,y,z robot arm, and the glass fiber fluorimeter. The integrated glass fiber fluorimeter allows sensitive on-line measurements in 960 channels within 5 s. Two different screening procedures were carried out. In a first experiment PCR reactions were done in the presence of the known PCR inhibitor hematin and its suppressor transferrin. The system was used to titrate the suppressor with the inhibitor hematin in order to determine the maximum inhibitor concentration tolerated at a given suppressor concentration. We processed 96 PCR samples in parallel with 11 different concentration steps. In a second experiment the 960-channel glass fiber fluorimeter was used to monitor on line the amplification of the Q␤ system in the presence or absence of an inhibitor ͑heparin͒. Since the doubling time of Q␤ RNA variants is about 20 s, on-line detection is crucial for the experimental setup. The evolution of new RNA species adapted to high inhibitor concentrations could be proved by comparison of the fluorimetric signal and electrophoresis.
