What is Synapt?
The SYNAPT G2-Si High Definition Mass Spectrometer from Waters is a hybrid quadrupole, ion mobility, orthogonal acceleration time-of-flight (oa-ToF) mass spectrometer that combines high resolution mass spectrometry with high efficiency ion mobility-based measurements and separation (IMS).
How does ion mobility mass spectrometry work?
In an ion mobility spectrometer, organic molecules are ionized and driven by an electric field against a counterflow of neutral drift gas. In their way to the detector, the ions collide multiple times with the drift gas, which reduce their speed. After each collision, ions are accelerated again by the imposed field.

Are mass spectrometers expensive?
Cost to Buy Mass Spectrometers Depending on your needs and purposes, purchasing a mass spectrometer for your lab can be alarmingly expensive. Units can range from under $10,000 to nearly $100,000. If you’re working on a budget, this one piece of essential equipment can really break the bank.
What do you mean by ion mobility?
Ionic mobility (μ) is the ability of charged particles to move through a medium in response to an electric field that is pulling them at a specified temperature and pressure. It is the drift speed acquired by the ions per unit applied electric field or potential gradient.
What type of evidence is ion mobility spectrometry used for?
Ion mobility spectrometry (IMS) is widely used for national security and law enforcement, placed at key transportation checkpoints such as airports and border crossings for the trace detection of drugs and explosives.
What is the most common mass spectrometer in the world?
The most popular type of mass spectrometer used for imaging involves a time-of-flight (TOF) analyser, which accelerates the ionized molecules along a straight path to a detector with an electrostatic field.
Where are mass spectrometers used?
Specific applications of mass spectrometry include drug testing and discovery, food contamination detection, pesticide residue analysis, isotope ratio determination, protein identification, and carbon dating.
Can mass spec be used alone?
These two components, used together, allow a much finer degree of substance identification than either unit used separately. It is not possible to make an accurate identification of a particular molecule by gas chromatography or mass spectrometry alone.
What is mobility of an electron?
In solid-state physics, the electron mobility characterises how quickly an electron can move through a metal or semiconductor when pulled by an electric field. There is an analogous quantity for holes, called hole mobility.
