Direct Analysis of a Methanol Flame by using a Compact High-Resolution Multi-Turn Mass Spectrometer

The InfiTOF™ is a compact high resolution time-of-flight mass spectrometer (TOF-MS) that has a unique multi-turn ion optics system capable of providing a variable-length ion-flight path (up to 200m) in a very compact analyzer (20cm x 20cm). As a result of this, the InfiTOF allows the user to choose a resolving power based on path length in order to separate similar mass gas components like carbon monoxide and nitrogen as CO+ (m/z 27.9949) and N2+ (m/z 28.0062).

Analysis of Reaction Gases in a PECVD Chamber: Reaction Analysis using a High-Resolution Mass Spectrometer

Plasma-enhanced chemical vapor deposition (PECVD) is an evaporation technique that forms various thin films on a substrate using a material gas in a low-vacuum chamber. PECVD, which decomposes the material gas via plasma, is widely used to develop silicon, silicon oxide, and silicon nitride films in semiconductor device fabrication.

Comprehensive 2D GC coupled with JEOL GC-HRTOFMS: GCxGC Applications

Diesel Fuel Analysis by GCxGC/EI (Hydrocarbon Classification); Biomarker Analysis by GCxGC/PI (Target Analysis using 2D EICC); Type Analysis by GCxGC/FI (Hydrocarbon Type Analysis); Synthetic Polymer Analysis by Pryolysis GCxGC/EI and FI (Unknown Compounds Analysis in Nylon 66); Additives Analysis by Pyrolysis GCxGC/EI and FI (Targeted Additives Analysis in Nitrile Butadiene Rubber); Natural Polymer Analysis by Pyrolysis GCxGC/EI and PI (Powerful Separation of the Main Components in a Japanese Lacquer Film); Soluble Organic Fraction Analysis by GCxGC/EI (Analysis of PAHs in Exhaust Gas); Electronic Waste Analysis by GCxGC/EI and Negative CI (Halogenated Compounds Analysis); Aroma Oil (Fragrance) Analysis by GCxGC/EI and FI (Molecular ion detection for Alcohol compounds); Sebum Analysis by GCxGC/EI (Pharmaceutical application)

Analysis of Pesticides in a Hemp Matrix

Hemp is a strain of Cannabis sativa that has multiple industrial uses including paper, plastics, woven goods, and even food. While certain strains of Cannabis sativa are well-known for their use as a recreational drug due the presence of the psychoactive compound tetrahydrocannabinol (THC), hemp strains are defined by the U.S. federal government as those that contain less than 0.3% THC.1 Additionally, hemp strains typically contain more cannabidiol (CBD),2 which was recently approved by the FDA to treat certain types of epilepsy, and is currently being investigated as a medical treatment for other afflictions.

Learning Polymer Materials Analysis from Natural Lacquer (Urushi)

Introduction: In recent years, polymer materials have become more complex due to increased composition and diversification so that a one-sided analysis is insufficient and multifaceted observations and analyses are required. In response to this need, JEOL has engaged in applied research under the keyword of "YOKOGUSHI" (multifaceted cross-instrumental) using various instruments organically. In this Urushi Note, multifaceted analysis methods for polymer materials are illustrated using the examples of natural lacquer (urushi) analysis.

Structural analysis of PET combining an on-plate alkaline degradation method & tandem TOFMS - MSTips 311

We investigated the structural analysis of the polyethylene-terephthalate (PET) polymer exposed to the on-plate alkaline degradation method by using the JMS-S3000 "SpiralTOFTM-plus" with TOF-TOF option. The SpiralTOFTM-plus uses an ultra-high resolution TOF for MS1 which allows monoisotopic precursor selection and a reflectron TOF for MS2 to analyze the product ion spectra produced from high energy collisional induced dissociation (HE-CID).
