                                               guaranteed minimum.

Resolution:                              165 to 850 nanometers.

Wavelength range:                  Two exit slit and detector assemblies.

Exit slit/detectors:                    Hamamatsu R427 solar blind and Hamamatsu R889 IR    enhanced for fall wavelength coverage.

SYSTEM OPERATION:

Torch ignition and control:       Fully automatic under host Computer program control.

                                               Up to 100 lines selectable per analytical method.

Analytical line selection:          Greater than 20,000 lines in library. Cross referenced by   element, wavelength, intensity, detection limits, and

                                               interfering elements.

Line library:                              Up to six sets of internal.standards per method.

Internal standards:                  Operator can be instructed by Computer when to run certain        samples and standards according to a previously

                                               programmed protocol.

Prompted mode:                     QC sample can be checked against programmable QC tables     to quality or performance specifications. Corrective actions       (restandardization, alarms, rechecking, etc.) can be                                                programmed to occur automatically.

Quality control checking:         Reported data can be restricted to wavelengths within analytical   range.

Line switching:                        Analytical mode allowing single element determination for sequential scan data

Quickquant:                             Automatic calculation of higher order derivatives of sequential       scans. Quickquant analysis of derivative scans.
