Trace elements in \(5-\mu\) l sample solutions deposited on a substrate were determined by secondary ion mass spectrometry employing the internal standard method. A simple sample mount made of copper was devised to restrict the sample residue within a small area. The absolute detection limits of 22
Secondary ion mass spectra and images were obtained from animal tissue samples using less than 10(13) primary ions/cm2. The mass spectra showed abundant peaks at m/z 184 and m/z 86. Tandem mass spectrometry (MS/MS) was used to identify the source of these ions as phosphocholine. Secondary ion images
