Breath analysis and cancer

As you know I LOVE Mass Spectrometry. In previous posts I told you what mass spectrometry is, how I use it to analyze coffee and how it was used in breath analysis to follow the menstrual cycle. Today, I want to explain how mass spectrometry, in particular PTR-MS, was used in cancer research. Scientists canContinue reading “Breath analysis and cancer”

What is mass spectrometry?

Previously I wrote about some applications of mass spectrometry and in particular of proton transfer reaction – mass spectrometry (PTR-MS). You can read old articles here (1, 2, 3, 4). Today I want to explain in details how PTR-MS works. PTR-MS is called a “non-targeted approach”. Non-targeted approaches are used to investigate samples when markerContinue reading “What is mass spectrometry?”

In a previous post I wrote about the fact that mass spectrometry is one of the tools used by food chemists. Now, I want to share with you a scientific article I recently published regarding coffee aroma. The story started when Nicky, a Thai student, came to our lab in Italy. She arrived with thousandsContinue reading “Something about mass spectrometry”
