Mass spectrometry (MS) is an analytical technique that determines the molecular weight of compounds and can therefore identify specific elements. Additionally, MS can tell you if the compound contains certain elements such as bromine and chlorine. The presence of these halogens is easily detected by noting the intensity ratios of ions differing by two atomic mass units (m/z). When combined with other identification techniques such as carbon and proton NMR and IR spectroscopy, mass spectrometry can be very useful when attempting to identify an unknown compound.

We have plates with a 3 mm spot, nine 3 mm spots, or an 18 mm spot for imaging. We just recently came out with a 50 mm x 19 mm plate, which includes a spot for a calibrant. Additionally, we have a new plate for DESI (desorption electrospray ionization) as well as our blotting substrates mentioned above. DIUTHAME is for one-time use.
Kohta Katsuyama is a marketing engineer in Hamamatsu’s San Jose, CA, office. His expertise is in mass spectrometry components and PMTs, and he is researching infrared and terahertz technologies. His busy home life with three children forces him to sometimes spend time in the kitchen, and his cooking specialty is stewed Japanese cuisine. He loved ramen so much that he finally did all the steps at home to make a bowl of ramen from scratch.
