Abstract
A carrier for use in preparing samples for spectroscopic analysis comprises a layer of abrasive material, e.g. sandpaper, created with a highly reflective material e.g. aluminium. The novel carrier reduces the effect of unwanted spectral components generated by the grit particle of the abrasive.
Claims9
A method of forming a sample of solid material for purposes of spectroscopic analysis, comprising the steps of:
- providing a carrier including a layer of an abrasive material, said layer being coated with a relatively thin coating of a highly reflective material;
- and
- abrading the solid material with the carrier to deposit a quantity of the solid material on the thin coating on the carrier.
