Coldspray-TOFMS : Analysis of Porphyrin Isomers by AccuTOF™ CS
Coldspray-TOFMS : Analysis of Porphyrin Isomers by AccuTOF™ CS

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.

Cold-Spray TOFMS: Effect of Retractable Flow Redirector
Cold-Spray TOFMS: Effect of Retractable Flow Redirector

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.

Direct analysis of stains on cloth caused by cosmetic
Direct analysis of stains on cloth caused by cosmetic

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.
