Description

  • Sample preparation is usually minimal or not required.

  • Analyzes up to 79 elements from Boron to Americium or their oxide compounds.

  • For each analysed element, UniQuant reports the Standard Deviation (Sigma) in ppm.

  • Supports analysis of samples in variety of physical forms, including multi-element solids, pressed powder with binder, small samples on supporting film, liquids or filter aerosol samples, and others.

  • Reports in weight percentage along with an estimated error for each element with reliable results.

  • For trace analysis, corrects for background, spectral impurities, spectral line overlaps, matrix effects and certain physical effects.

  • At high power analyses are done in less than 14 minutes; samples belonging to a known family, requiring fewer measuring channels, may be analyzed in 5 minutes.

  • For specific applications where very high accuracy is required, UniQuant Software may use a specially-calibrated data set.

Thin Layer Samples

  • Mono-layer samples: UniQuant Software can calculate the sample mass along with its associated standard deviation concurrently with the composition of the layer; if the layer is on a substrate with elements that are also in the layer, UniQuant Software can take their effect into account.

Interactivity

  • User interface designed for minimum number of key strokes or mouse clicks to perform an operation.
  • Facilitates rapid changes in assumptions (e.g. sulfides v. oxides) for composition determinations of an unknown sample.

Batch Modes

  • For evaluation of calibration (set-up) samples as well as for evaluating a suite of unknown samples.
  • Samples are “tagged” in a directory and the process is started.
