No.4 MS Technology for precise metabolite measurements
The process of glycolysis is closely involved in diseases such as diabetes and cancer. Using a particular GC-MS technology, researchers at a collaborative laboratory of Shimadzu and Osaka University are able to completely separate different sugar phosphates and precisely measure the isotope labelling ratio.
Which GC-MS technology is this?
- □ A PCI mode
- □ B NCI mode
- □ C SIM mode
- □ D EI mode
No.3 Shimadzu’s Unique UF Technologies For High-Speed Measurement
Shimadzu’s LCMS-8000 series comes equipped with UFMS (Ultra-Fast Mass Spectrometry) technologies which enable greater speed, sensitivity and ease-of-maintenance.
Which of the below Shimadzu technologies reduces the lower limit on the length of the collision cell while achieving high CID efficiency and ultra-fast ion transport speed?
No.2 Nobel Prizes in Mass Spectrometry
Which of the following Nobel Prize winners was not awarded the prize for contributions to the field of mass spectroscopy?
No.1 Measuring mass from time of flight: TOFMS
TOFMS works on the principle that it takes longer for larger molecules than smaller molecules to travel between the ion source and detector. The mass of the molecule is calculated from the time taken to traverse a certain distance.
In the Shimadzu TOFMS “AXIMA series”, molecules are accelerated by a 20 kV source, and the distance between the ion source and detector is 1.2 m.
So try your hand at our quiz questions below!
A Shimadzu engineer is using this TOFMS to measure an amyloid peptide with a molecular weight of 4,331 amu. What does this molecule travel at approximately the same speed as?
In this case, how long does it take for the molecule to travel between the ion source and the detector?
