Stable Isotope and Environmental Laboratory

stable isotope ratio mass spectrometerThe Stable Isotope and Environmental Laboratory (SIEL) is located in the Department of Geology and Geological Engineering at Colorado School of Mines and provides analytical training and services relevant to geosciences and (paleo)environmental studies to students, faculty, and other researchers at Mines, other universities, federal agencies and industry.

The centerpiece of the facility is an IsoPrime Isotope Ratio Mass Spectrometer (IRMS) currently measuring the stable isotope ratios of carbon and nitrogen of solid organic samples. The laboratory also offers analytical methods for the characterization of organic, carbonate, and volatile-rich soil and rock samples (loss-on-ignition analysis).

SIEL also conducts pollen-based research which represents an important tool in stratigraphy, paleoenvironmental studies, archaeology, and forensic investigations.

  • EuroVector Elemental Analyzer

The SIEL is also equipped with a fully operational sample preparation facility. This includes dry and wet lab facilities.

THERMO SCIENTIFIC THERMOLYNE BENCHTOP MUFFLE FURNACE

The furnace has a heating area of 2 L and can be operated over a temperature range of 100 to 1200°C.

DRYING OVEN

FISCHER SCIENTIFIC FS30H ULTRASONIC BATH

Ultrasonic precision cleaning bath for small- and medium-sized objects that can also be used for sample preparation and degassing of liquids. The bath is equipped with a stainless steel basket.

FRITSCH PULVERISETTE 23

The ultra-compact mill is ideal for fine comminution of smallest quantities of medium-hard, brittle and moist samples (wet, dry, or cryogenic). Its special spherical grinding bowl ensures a high performance in grinding, mixing, and homogenizing.

ROTANTA 460 CENTRIFUGE

This high performance centrifuge has a maximum capacity of 4×750 ml, with a maximum of 15,000 rotations per minute and a maximum relative centrifugal force of 24,400 g.
