LPI Science Labs and Equipment

The LPI hosts a variety of experimental and analytical equipment, facilities, and laboratories that are available to LPI science staff in support of their research.

Scanning Electron Microscope

The LPI maintains a benchtop SEM, a Phenom XL from Nanoscience Instruments. It is intended for imaging, elemental mapping, and semi-quantitative chemical analyses of planetary samples as a precursor to detailed analyses with the dedicated instruments at ARES/JSC. The Phenom has a CeB6 electron source, which provides a tight, bright electron beam for high-resolution imaging in secondary electrons (SEI) and high contrast imaging by backscattered electrons (BEI). The Phenom carries a large-area SDD X-ray detector, which permits the rapid collection of elemental maps and low-noise EDS spectra for semi-quantitative chemical analyses.

Raman Spectrometer

The LPI has a benchtop Raman spectrometer system, a Raman-HR-TEC-785 system from StellarNet, Inc. The spectrometer is suitable for lab and field office use and is intended to provide quick mineral analyses and mapping of planetary and planetary analog samples. The system uses a laser of 785 nm wavelength (near-infrared) to suppress fluorescence and a spectrometer covering Raman shifts of 200–2650 cm–1 with a resolution of 4 cm–1. The system’s dedicated software includes a Raman spectral library and a search tool.

Petrographic Microscope

The LPI maintains a research-grade petrographic microscope, a Leica DMX-R, which includes transmitted and reflected light optics. Attached to the Leica is a SpotFlex camera, which produces publication-quality images, up to 64 megapixels, with true 24-bit color on each pixel (no Bayer mask).

Rock Preparation Laboratory

The LPI maintains a rock preparation laboratory to allow sample splitting and preparation of mounts for a variety of applications. The lab has a rock splitter, wafering saws, grinding and polishing wheels, a vacuum impregnation system, an ultrasonic bath, hot plates and an oven, a petrographic microscope, and binocular microscopes.

Laboratory for the Astrobiological Exploration of Subsurface, Subaqueous, and Salty Environments (LASSSE)

LPI maintains a research staging and storage space that hosts –80°C and –20°C freezer units and a standard refrigerator and freezer for sample and consumables storage. This space also houses the growing Planetary and Astrobiology Analog Field Research Toolkit. This toolkit provides LASSSE team members and other LPI researchers the necessary tools to execute planetary and astrobiology-related field science successfully. Several of the major instruments are also capable of laboratory-based analyses (see below). Note: All equipment in the Field Research Toolkit is available to all LPI researchers for both field and lab-based analysis.

Spectral Evolution oreXpress portable Visible Near-Infrared Spectrometer
The oreXpress portable spectrometer has a spectral range of 350–2500 nm and a spectral resolution of 2.8 nm @350–1000 nm, 8 nm @1500 nm, and 6 nm @2100 m. The spectrometer has a handheld contact probe combined with a high signal-to-noise ratio and a portable handheld, sunlight-readable display to make in situ field analysis fast and efficient. The entire system fits into a specially designed backpack to make field deployment easy. The system at LPI also comes with a Benchtop Reflectance probe and powder sample holders to make the spectrometer capable of laboratory analyses.
