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.

In this study, we report on the simultaneous analysis of TSCA and RoHS by using GC/MS/MS.

We introduce an analysis example in which the hydrogen generated when steel pins are heated using a pyrolyzer is directly detected by a mass spectrometer.

In this study, we compare the results of various cold splitless injection methods using MMI to improve GC-MS/MS detection sensitivity by suppressing adsorption and thermal decomposition of the target pesticides in the GC inlet.

In this study, the results of using the EPIS as an ion source on the detection sensitivity in an analysis similar to MSTips No. 413 (application of cold splitless injection method) are presented.

In this study, the results of a comparison of the detection sensitivity enhancement effect by an analysis combining the cold splitless injection of an MMI as the GC sample injection method and the enhanced performance ion source (EPIS).

In this MSTips, we will introduce an example of applying group analysis to the analysis of vinyl acetate resin.

In this MSTips, we will introduce additive compounds analysis results using this group analysis function with "additive list".
