What is smallest mass spectrometer?

A micro mass spectrometer is the smallest mass spectrometer that is designed to be compact and portable, making it suitable for field analysis and point-of-care diagnostic applications. It can detect and analyze smaller quantities of samples, taking as little as a few microliters, and can provide fast and accurate results within minutes.

Micro mass spectrometers use a range of ionization techniques including electron impact, electrospray ionization, and laser desorption/ionization. They are equipped with mass analyzers, such as quadrupole, time-of-flight, and ion mobility spectrometry, to separate and identify ions based on their mass-to-charge ratio.

Some advantages of micro mass spectrometers include their sensitivity, specificity, and versatility. They can be used in a variety of fields such as pharmaceuticals, environmental analysis, food safety, and forensic science.

Examples of commercial micro mass spectrometers include the Agilent 5977B GC/MSD and the Waters SYNAPT G2-Si HDMS.
