The Sample Preparation Service groups several laboratories for the preparation of samples of different nature, to perform various types of analysis. Each laboratory has specific technical personnel and scientific advisors.
This laboratory prepares thin sections, polished thin sections and polished blocks for study using transmitted and reflected light microscopy and electronic microprobe, transmission electron microscopy and laser ablation. Furthermore, doubly polished sections are also prepared for study of fluid inclusions, and sections and blocks of mineral concentrates are also prepared.
The laboratory is equipped with a Struers Planopol – V polishing wheel, a Microtec automatic thin sectioning system, a Petro-Thin sectioning system by Buehler, two microscopes (one transmitted, the other reflected light), complementary apparatus, etc.
Responsible technician: Sonia Sánchez Librero
Scientific advisor: Fernando Gervilla Linares
The laboratory is equipped with apparatus for sample preparation for subsequent analysis using a number of techniques:
The laboratory includes a disk mill Retsch DM200, a vibratory disk mill Retsch RS200, a sieve shaker Retsch AS200, jaw crushers Retsch BB200, Wilfley shaking table, a Frantz isodynamic magnetic separator, tungsten carbide, steel and agate mortar grinders.
Responsible technician: Inmaculada Martínez Segura
Scientific advisor: César Viseras Iborra
This laboratory is used for sample preparation, in particular for preparation of fused beads and pressed pellets of powdered samples for X ray Fluorescence analyses, for digestion of samples for analysis by atomic absorption (AA), Inductively coupled plasma mass spectrometry (ICP-MS) and Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES), and for mineral separation by sequential chemical leaching.
The laboratory is equipped with two fume hoods for the acid attack of samples and the use of different types of reagents, as well as with precision balances, ovens and furnaces, ultracentrifuges and an accessory laboratory material.
