JEM-3300 (CRYO ARM 300 II) Cryo-Electron Microscope

CRYO ARM™ is an electron microscope for observing biomolecules such as proteins at cryo temperature. The microscope equips a cold field-emission electron gun, an in-column Omega energy filter, a side-entry liquid nitrogen cooling stage, and an automated specimen exchange system. The specimen exchange system can store up to 12 specimens in the specimen exchange chamber.

JEOL present at the 42nd ISCC & 15th GCxGC Symposium from May 13-18

JEOL will be present at the 42nd International Conference Symposium on Capillary Chromatography (ISCC) jointly organized with the 15th GCxGC Symposium, which will be held this year in Riva del Garda, Italy from May 13th-18th.

We will have a booth displaying our latest developments, which will be presented in detail during a seminar.

The last conference in 2016 was very successful with 830 participants, from all around the world, and with 41 exhibitors.

This year particular emphasis will be directed to all Comprehensive Separation Technologies and MS Hyphenation and to capillary chromatography and 2D GC with various forms of MS from unit-mass to high resolution, and from single to hybrid analyzers.

JEOL (Europe) BV introduces: Photo Ion-Source for JMS-T200GC AccuTOF GCx

Electron ionization (EI), generally used for GC/MS and GCxGC/MS analysis, produces fragment ions. Fragments are valuable for database search and compound identification. However, fragmentation adds an additional level of complexity in interpreting complex mixtures, such as crude oil. Some compounds (e.g. alkanes, alcohols) do not produce abundant (or any) molecular ions.

Since photoionization (PI) is a softer ionization method than EI, molecular ion can be easily distinguished using this technique. For some analytes, characteristic fragment ions may also be observed. Combining soft ionization with high-resolution exact-mass data and new software tools simplifies processing of complex GC and GCxGC data (e.g. petroleum type analysis).

PI provides clear molecular ions and elemental composition that can be combined with EI data to identify unknowns and also provides selective ionization of target compounds

The JEOL PI source is designed as a PI/EI combination ion source. Switching between PI and EI can be done without breaking vacuum of the ion source, even without breaking any vacuum. Also during an analytical run it is possible to switch between PI/EI and vice versa. The accurate mass will always stay available whatever ionisation technique is used with our JMS-T200GC AccuTOF GCx.

At this moment a PI source is available for our GC-TOF and GC-Quadrupole systems.
