An improved mass spectrometry method comprises the analysis of ferrocenyl boronate derivatives of compounds of interest. The TMR read sensor has an AFM layer recessed from the air bearing surface, providing a reduced shield-to-shield distance. The lateral wall outside panel can have secured to it an end cap, which at an end lying in the longitudinal direction of the sillboard profile exhibits a floor section that is essentially indentation free in relation to the transverse direction of the vehicle and spaced apart in the vertical direction of the vehicle from a bottom side of the lateral wall outside panel. Requested modulation method deciding section 207 decides a modulation method to be requested to the base station using the reception quality of pilot signals and the detected Doppler frequency.
