Introduction and System Description Matched to the customers need The PerkinElmer AS-93plus autosampler is a computer-controlled, multi-purpose sampling system for flame AA, ICP-OES and ICP-MS. The AS-93plus automates standard and sample introduction for instrument calibration and sample analysis, extending the spectrometer’s capabilities to those of a fully automated analytical workstation. The AS-93plus is computer-controlled using PerkinElmer AA WinLab, ICP WinLab or ELAN ® software. The autosampler is operated from the keyboard and screen of the spectrometer system; the autosampler itself does not have any operating controls. The autosampler does not incorporate any device for active sample aspiration but merely moves its sampling probe into the individual containers with the calibration and sample solutions. For solution aspiration the sampling probe must be connected via a sample tube to an active module. An active module can, for example, be the nebulizer of an AAS burner, the pump of a flow injection system, or the pump of an ICP nebulizer assembly.

Key benefits: • fast, accurate random access • large, flexible sample capacity • standard rack configurations • corrosion-resistant sampling components • automatic rinsing Fast, accurate random access An advanced drive system moves the sampling arm of the AS-93plus in the X and Y coordinates simultaneously, minimizing changeover time between samples. High precision digital stepper motors move the AS-93plus sampling arm to its programmed X-Y-Z coordinates quickly and accurately. Random access programming gives the user exceptional flexibility in locating different samples and calibration solutions. Large, flexible sample capacity Sample capacity with the AS-93plus is up to 200 samples per sample rack. Sample racks are easily interchanged, reducing analysis set-up times and giving the user the flexibility to use differently sized sample vessels matched to his analytical needs. Standard rack configurations In addition to the variety of sample racks offered by PerkinElmer, the AS-93plus is also compatible with commonly used laboratory sample rack configurations from other manufacturers, such as Scienceware or Gilson. Corrosion-resistant sampling components The sample probe assembly, including the sample transport capillary tubing, is made entirely of acid- and solvent-resistant PTFE. Automatic rinsing The autosampler includes a flow-through rinsing port so that the sampling probe is always rinsed with fresh rinse liquid, significantly reducing the risk of carryover. This is especially advantageous when samples with very different element concentrations have to be analyzed. Rinse liquid is pumped in a stream through the rinsing port by a peristaltic pump that is built into the autosampler. The pump operates during the rinse phase of the measurement cycle (i.e. every time that the sampling probe enters the rinsing port) and is idle during other phases of the cycle. You can select or change for how long the rinse pump is switched on via the Rinse download utility. AS9N010B.STB 5 of 68
