Analytical Instrument Documents

In this work, we analyzed the SAAF from a ciona intestinalis by using a JMS-S3000 SpiralTOF™ equipped with the optional TOF-TOF analyzer to generate a high energy CID product ion spectrum for this compound.

In a previous application note, we reported the analysis of bovine serum albumin (BSA) by Spiral and Linear modes. In this work, we show the analytical result for BSA by using the JMS-S3000 "SpiralTOF" with the TOF-TOF option.

This application note shows that FI is a suitable technique to determine the molecular weight of compounds which are not producing molecular ions in EI or CI.

We have compared FD and desorption electron ionization (DEI), which are both direct sample introduction methods, for the analysis of an organic electroluminescence material with many aromatic rings.

This application note shows the result of a commercial lube oil by GC/FI and the elemental composition determination by FI.

This application note shows the results of the qualitative analysis for sulfur-containing substances in diesel oil by GC x GC-TOFMS.

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.

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.

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.

In this application note, we report on the analysis of pigment component in polymer by using DIP-MS/MS.
