The molecular ion M+· was observed when the liquid sample of butyrophenone was supplied using atmospheric pressure corona discharge (APCD). In contrast, the vapor supply resulted in the formation of the protonated molecule [M+H]+. The mass spectrum obtained with the liquid supply showed two distinctive fragment ions at m/z 105 and 120, resulting from α-cleavage and McLafferty rearrangement (McLR), respectively.

Rapid Analysis for α-Tocopherol and Its Oxidative Products in the Pisum sativum L. Leaf Using Supercritical Fluid Chromatography-Medium Vacuum Chemical Ionization Tandem Mass Spectrometry
Toshinobu Hondo, Yumi Miyake, Michisato Toyoda
A method for the rapid determination of α-tocopherol (α-T) and its oxidative products in plant tissue has been developed using supercritical fluid extraction (SFE) coupled with supercritical fluid chromatography (SFC) and medium vacuum chemical ionization (MVCI) with tandem mass spectrometry. The method is

Quantitation of Host Cell Proteins by Capillary LC/IMS/MS/MS in Combination with Rapid Digestion on Immobilized Trypsin Column Under Native Conditions
Ryota Tomioka, Kosuke Ogata, Yasushi Ishihama
Host cell protein (HCP) impurities are considered a critical quality attribute of biopharmaceuticals because of their potential to compromise safety and efficacy, and LC/MS-based analytical methods have been developed to identify and quantify individual proteins instead of employing enzyme-linked immunosorbent assay to assess total HCP levels.

Comprehensive Membrane N-Glycoproteomics Using Human Breast Cancer Cell Line Pairs
Daisuke Takakura, Haruka Yoshida, Shoko Ohashi, Nana Kawasaki
Aberrant glycosylation of membrane proteins is a hallmark of cancer and a useful molecular marker for the diagnosis of breast cancer (BC). However, the molecular mechanisms by which altered glycosylation affects the malignant transformations associated with BC are poorly understood. Accordingly, we performed comparative

Identification of Negative Ion at m/z 20 Produced by Atmospheric Pressure Corona Discharge Ionization under Ambient Air
Shiho Fujishima, Kanako Sekimoto, Mitsuo Takayama
The negative ion at m/z 20 observed at atmospheric pressure corona discharge ionization mass spectra has been identified by supplying the vapors of deuterium oxide (D2O) and H218O.

A Short-Term Time-Series Data Analysis Algorithm for Flavor Release during the Start of Eating
Takehito Sagawa, Motoshi Sakakura
“Retronasal aroma” refers to the aroma released from food during consumption and traveling through the nose after leaving the mouth. It is closely related to the behavior of odor compounds released from food into the mouth and plays a crucial role in our overall perception of flavor. As a result, research focusing on measuring the behavior of retronasal aroma has gained attention for exploring the relationship between sensory perception and flavor.
