About Microsaic Systems

Microsaic Systems plc (AIM: MSYS) is a high technology company developing chip-based, bench-top and point-of-analysis mass spectrometry (“MS”) instruments that are designed to improve the efficiency of pharmaceutical R&D and manufacturing. The Company is working with established global life science companies to co-develop new solutions to improve productivity in the development of small molecule and novel biologic (peptides, antibodies) medicines. MS is a powerful method of analysis to enable earlier decision making relating to product identification, purity and bioactivity, and is the analytical technique of choice for biochemists across many industry sectors.

Microsaic’s core product, the 4500 MiD®, is a robust and compact MS system, retaining the functionality of larger conventional MS systems, is easier to use by non-specialists, consumes less energy and has lower running costs. For more information, please go to
