A schedule recording section (4) records a user's schedule. A SOC (state-of-charge) optimization planning section (5) plans the SOC of a rechargeable battery (21) based on the user's schedule. The planned control target SOC is optimized through a comparison between the continuous charging characteristic of the rechargeable battery (21) and the length of an operable period or the amount of electric power to be secured at the time of battery-powered operation. For example, a control target SOC is set at a full charge in the proximity of the period during which a battery-powered operation time is expected to be long. A control target SOC is set lower enough than a full charge in the period during which a connection to an external power supply (A) by the AC adapter (11) is expected to continue for a long time. A power-supply control section (3) controls the charge and discharge of the rechargeable battery (21) according to a plan for the optimization of the SOC.

Relative quantification of metabolites by Electrospray Ionization Mass Spectrometry (ESI-MS) requiring a mechanism for simultaneous analysis of multiple analytes in two or more samples. Labeling reagents that are reactive to particular compound classes and differ only in their isotopic kit facilitating relative quantification and providing tangible evidence for the existence of specific functional groups. Heavy and light isotopic forms of methylacetimidate were synthesized and used as labeling reagents for quantification of amine-containing molecules, such as biological samples. Heavy and light isotopic forms of formaldehyde and cholamine were also synthesized and used independently as labeling reagents for quantification of amine-containing and carboxylic acid-containing molecules, such as found in biological samples. Advantageously, the labeled end-products are positively charged under normal acidic conditions involving conventional Liquid Chromatography Mass Spectrometry (LC / MS) applications. Labeled primary and secondary amine and carboxylic acid end-products also generated higher signals concerning mass-spectra than pre-cursor molecules and improved sensitivity. Improved accuracy concerning relative quantification was achieved by mixing heavy and light labeled Arabidopsis extracts in different ratios. Labeling strategy was further employed to ascertain differences in the amounts of amine-containing metabolites for two strains of Arabidopsis seeds.

The present invention provides methods for enhancing the fragmentation of peptides for mass spectrometry by modifying the peptides with a tagging reagent containing a functional group, such as a tertiary amine, having a greater gas-phase basicity than the amide backbone of the peptide.
