AccuTOF™ LC, Mass Spectrometry (MS), MS Application Notes |

Dr. Furuta of Kyushu University has been studying membrane transport of proton and specific anions using porphyrin compounds. He has reported that multiple N-confused expanded porphyrin, which combines rotating and expanding characteristics of intramolecular pyrrole ring in N-confused porphyrin (NCP), an isomer of porphyrin, is effective for membrane transport.

AccuTOF™ LC, Mass Spectrometry (MS), MS Application Notes |

In 2003 JEOL announced the JMS-T100CS AccuTOF CS, incorporating a new ion source designed to support cold-spray ionization. The new ion source features a retractable flow redirector designed to switch the direction of spray between vertical and coaxial. We analyzed proline in an AccuTOF CS, studying the effect of the retractable flow redirector.

AccuTOF™ LC, Mass Spectrometry (MS), MS Application Notes |

Foundation is one of the essential cosmetics for women. At the mean time, it often makes a stain on clothing. We directly analyzed foundation stains on cloth (Fig. 1) without sample preparation by using DART (Direct Analysis in Real Time) ion source installed on AccuTOF™ LC series. Foundation from 3 manufacturers were measured and compared.
