TestAll Geo Mode

Using General Metals Mode

Thermo Scientific
Use this mode to analyze samples composed of potential metal ore - rock containing high
proportions of metal - and containing Ta and/or Hf. This mode will return an elemental
composition of the ore sample as analyzed. Ore Composition is output by default in terms of
percent of composition by weight.
See "Using Mining Ta/Hf Mode" on page 44.
Use this mode to analyze samples composed of unknown and/or mixed composition, such as
toys and consumer products. This mode will attempt to return a general Material
Identification by comparing the analysis with other general types of materials. It will select the
proper sub-mode for analysis and return an elemental composition of the sample as analyzed.
Material Elemental Composition is output by default in terms of parts per million.
See "Using TestAll Mode" on page 44.
Use this mode to analyze powder, mineral, and ore samples without first determining whether
the samples would best be analyzed with Mining or Soil Mode. This mode uses both the
Compton Normalization calibration (Soil) and the Fundamental Parameters calibration
(Mining) to determine whether the soil calibration is acceptable or whether the total metal
content is too high for Compton mode. It will then return an elemental composition of the
sample as analyzed. If the sample can be analyzed via soil mode, then the analyzer will display
results from both Soil and Mining Modes in one unified list. If both calibrations contain the
same element, then the mode that has the lower detection limit will be displayed. Material
Elemental Composition is output by default in terms of both parts per million (mg/kg) and
percent of composition by weight, with 0.10% being the cutoff point.
Note Due to the nature of this mode, your analyzer will only use factory calibrations. User
modified Cal Factors will not be available.
See "Using TestAll Geo Mode" on page 44.
1. Clean the sample to be analyzed so it is free of all surface contamination, grinding the
surface if appropriate.
2. Place the analyzer so that the sample covers the analysis window.
3. Select the Mode icon.
