Apex IV FT-ICR
The Apex IV FT-ICR is a Fourier-transform ion cyclotron resonance
instrument with a 7.0 Tesla superconducting magnet. It was originally
installed in the Biochemistry department in 2002, but was moved to the
Mass Spectrometry facility in 2005 and had a new magnet installed. The
instrument runs a combination of high-resolution service work and
high-end research driven analyses.
