Mass spectrometers, measuring the mass-to-charge ratio of charged particles to determine their molecular weight, have not quite become a routine acquisition for every lab that might benefit from them. Four parts are standard in all mass spectrometers: a sample inlet, an ionization source, a mass analyzer, and an ion detector.
Top 6 Questions You Should Ask When Buying a Mass Spectrometer
- What factors come into play when determining the MS specifications you require in terms of throughput, sensitivity, robustness, software control, ease of use, and ease of maintenance?
- What differentiates the vendor’s MS from others offered, in terms of performance and how easy it would be to upgrade?
- How do you validate the specification claims presented by the vendor?
- Has the data processing software been designed for enhanced analytics, with lab workflow in mind and does it support critical compliance requirements?
- What are important price points to keep in mind when selecting a MS?
- Laboratories need fast and effective services, including an effective distribution of spare parts, instruments, service personnel, and education/ training. How does the company serve these needs globally?

Nearly 60% of respondents are engaged in purchasing a new mass spectrometer. The reasons for these purchases are as follows:
|Upgrading older system||
|Require higher quality data||
|Setting up a new lab||
|Looking for more mass accuracy and resolution||
|Require shorter run times/increased lab throughput||
|Integrating MS from traditional HPLC to UHPLC||
|Trying to reduce operating costs||
|Looking to reduce the usage of solvent and waste||
|Require a smaller footprint for the instrument in the lab||
|Looking for a complete system that includes data handling and storage||
|We require more precise and accurate flow rates||
