Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) ESI New Wave NWR193 laser ablation system coupled to an Agilent 7500cs ICP-MS The Museum’s dedicated laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) system is capable of low-level trace element determinations in most solid materials, with minimal sample destruction and spatial resolutions of 1-150 microns. central air conditioning units compare brandsPrecise uranium-lead (U-Pb) age determinations can be obtained in zircons and other accessory mineral phases.hvac unit heat pump The instrument used for analysis is an ESI New Wave NWR193 Laser Ablation system coupled to an Agilent 7500cs Inductively Coupled Plasma Mass Spectrometer.carrier heating and cooling wall unit

a laser beam is focused and fired at the surface of a sample held in a chamber the energy of the laser beam is transferred to the sample and causes material to be removed (ablated). the material removed is picked up in a flow of gas passing through the sample chamber and transported to an inductively coupled plasma mass spectrometer (ICP-MS) as the material passes through the inductively coupled plasma it is ionised the ions are separated in the mass spectrometer according to their mass-to-charge ratio and then counted on a detector To fully quantify data the concentration of an internal standard must be known prior to laser analysis. The purpose of the internal standard is to correct for the differing physical properties and ablation characteristics of samples and reference materials. Typically the concentration of a major element as determined by electron probe microanalysis (EPMA) is used as an internal standard. Samples do not need surface preparation, but data quality is improved considerably if the samples are polished.

Samples should be clean, dry and where possible any carbon coating from previous electron probe microanalysis should be removed. Any gold coating on samples previously imaged by scanning electron microscopy or ion probe analysis must be removed thoroughly. Residues of gold coating can severely affect LA-ICP-MS data quality. Samples that need to be prepared (cut, mounted and polished) should be presented to the preparation laboratory at least four weeks prior to the LA-ICP-MS booking. Sample sizes that can be accommodated Prepared materials: these are normally presented in the form of 25mm diameter polished blocks or polished thin/thick sections of 48mm x 26mm (typical probe size).  Tissue section sizes and 25mm circular sections can also be accommodated. Odd section and block sizes may also be accommodated. Please contact for further information Unprepared samples: oddly sized and shaped samples may be accommodated up to the size of the sample chamber (100mm x 100mm x 20mm).

LEO 1455 VP SEMZeiss EVO 15LS SEMZeiss Ultra Plus Field Emission SEMFEI Quanta 650 FEG SEMCameca SX100 electron microprobeThe ICTA-ICP building, located in the UAB Campus (Universitat Autònoma de Barcelona), is a research centre in environmental sciences and palaeontology. In accordance with the research fields of the building users, they chose, from the beginning, a building prepared to give an ambitious response to the challenges of sustainability. The building, an isolated volume of five floors of 40x40m2 and two basements, contains the following program: on the ground floor the hall, bar, classrooms, meeting rooms and the administration area; the next 3 floors hold the offices and laboratories; on the roof there are vegetable patches together with the resting areas. The semi basement holds the parking and the engine rooms while the basement contains the warehouses and other laboratories. Both offices and laboratories are spaces with a lot of internal load and therefore tend to be hot.

The building has been designed to take profit from this internal situation in winter while it tends to dissipate it in summer. It has been thought as an adaptable and flexible infrastructure able to suffer changes of use, developing several simultaneous strategies that work complementarily. A long life and low cost concrete structure with a lot of inertia has been chosen as the main structure, contributing directly to the passive comfort of the building. The quantity of concrete has been optimized distributing its mass in favour of the thermal exchange. It uses a post-stressed concrete slabs with pipes in the central area where the air circulates, in order to build a lighter structure. At the top and bottom of the slab the thermal mass is activated by geothermal energy. The concrete structure is wrapped and protected by a low cost exterior bioclimatic skin. By installing a greenhouse industrialized system that opens and closes its mechanisms automatically, the solar gain and ventilation are regulated.

This way, it is possible to raise the interior temperature naturally and guarantee a base of comfort in the circulation spaces as well as in the in-between spaces. In the middle of the building four patios, with stairs that connect the different levels at certain points, guarantee light and ventilation in all workspaces reducing the consumption of artificial lighting. These patios, as well as the in- between spaces and the perimeter gallery, contain several plant species that allow to improve the comfort through the adjustment of the humidity gradient. The building also takes advantage of the contact of the two basements with the terrain to pre-acclimatize the air renovations of the building through two air chambers: one generated by “PI” beams that make up the retaining walls and the other, the air chamber underneath the basement floor. Inside this improved climate there are well-insulated wooden boxes, with practicable glass openings that help to achieve the comfort conditions of the workspaces.

The distribution of these boxes is different on each floor depending on the needs of each user creating generous and indeterminate interstitial spaces. These spaces link with the circulations generating more informal meeting and resting areas. The building has been designed to host three types of climates associated with different intensities of use: Climate A: in-between spaces, that are exclusively acclimatized/heated by passive and bioclimatic systems; Climate B: offices, that combine natural ventilation with radiant and semi-passive systems; Climate C: laboratories and classrooms that have a more hermetic and conventional functioning. Each type of climate has its own associated systems. The behaviour of the building is monitored and controlled by an automatic computer system that processes and manages an important set of information in order to optimize both comfort and energy consumption. The system has been programmed in favour of the maximum passive behaviour of the building and to minimize the use of non-renewable energy sources.
