Instruments & Resources

The Environmental Molecular Sciences Laboratory (EMSL) is home to the user facility’s 150 instruments that can be leveraged for biological, environmental, and computing research needs. The instruments and resources are available to researchers who are awarded funding through EMSL’s open call for proposals. The categories below reflect instrument groups for specific research areas. When selected, the instrument group is filtered by the instruments that fall under that category. By reviewing the instrument pages, researchers can learn how the instrumentation can be applied to research. The instrument and resource pages can also be used to identify the instrument owners and Integrated Research Platform area leads to follow up with questions before submitting an abstract to a call for proposal.
