Top 6 Questions You Should Ask When Buying a mass spectrometer
1. 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?
2. What differentiates the vendor’s MS from others offered, in terms of performance and how easy it would be to upgrade?
3. How do you validate the specification claims presented by the vendor?
4. Has the data processing software been designed for enhanced analytics, with lab workflow in mind and does it support critical compliance requirements?
5. What are important price points to keep in mind when selecting a MS?
6. 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?
