    Sammanfattning : Despite valuable advantages of mass spectrometry (MS) techniques they still have drawbacks that need to be overcome, notably their sensitivity to various kinds of interfering substances and associated difficulties involved in detecting signals from analytes present in trace quantities. Thus, high quality analytical data could be acquired by improving sample pre-treatment techniques and/or ionization methods to increase ionization yields and/or avoid the generation of unwanted ions.

    Sammanfattning : Mass spectrometry imaging (MSI) has emerged as a valuable approach for mapping multiple molecular species in sections of diverse tissues. It enables simultaneous detection of numerous compounds (from neurotransmitters to small proteins) in the brain at relatively high lateral resolution (>5 μm) on a routine basis. LÄS MER
