A method for the quantatitive determination of pethidine in human urine by liquid secondary ion and tandem mass spectrometry is presented. Quantification was carried out by using ketamine as internal standard. It was found that the collision-induced dissociation (CID) spectrum of the [M H] ion of pe

Quantitative analysis of the native oxide on silicon wafers has been investigated by secondary ion mass spectrometry (SIMS) combined with an encapsulation method. In the encapsulation technique, the sample surface is covered with a thin Γlm whose material is identical to that of the substrate of the
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
## Abstract Time of flight secondary ion mass spectrometry (ToFβSIMS) is an ideal technique for the analysis of adsorbed protein films because of its surface sensitivity and chemical specificity. In this study, we examined ToFβSIMS with the multivariate calibration method partial least squares regr
