Available Instrumentation
One of the best aspects about the sciences at Trinity is how we share instrumentation between departments and programs. Here are few of the instruments that the ENVS program faculty maintain.
Chemistry
PanAlytical X’PertPRO X-Ray Diffractometer (XRD) – XRD in combination with powerful analytical software (HighScore Plus) provides chemists, geologists and engineers with state of the art solid phase identification.
Milestone DMA-80 Total Mercury Analyzer (DMA-80) – Housed in the environmental science lab, the DMA-80 analyzes solid and liquid samples for total mercury to ppb levels.
ThermoScientific (Dionex) Ion Chromatography (ICS-1100) – In the fall 2012 we updated the IC and auto sampler in the environmental science lab. The IC-1100 is set up for major anions: (fluoride, chloride, nitrite, bromide, nitrate, phosphate and sulfate). For cations we use the ICP-OES in the Chemistry instrumentation lab.
Elementar vario EL cube CNS analyzer to analyze C,N and S concentrations in sediment and soil samples.
The Chemistry Department has an entire building full of instruments that are available for research. A list of equipment can be found here.
Geophysics
AGICO JR6 Spinner Magnetometer – capable of measuring the magnetic remanence of rock specimen with a resolution up to 10-6 A/m.
AGICO KLY-4S Susceptibility Meter with CS3 Furnace and CL3 Cryostat Attachments – measures magnetic susceptibility of natural samples at room temperature and anywhere from -194⁰C up to 700⁰C.
AGICO MFK-2 Multi-function Kappabridge – measures magnetic susceptibility at various frequencies and anywhere from -194⁰C up to 700⁰C. Could also measure anisotropy of susceptibility/
