About Microsaic Systems

Microsaic Systems develops and sells chip-based scientific instruments for the chemical identification of substances. The Company's products are based on the 'gold-standard' scientific technique of mass spectrometry.

Microsaic Systems has developed a miniaturised mass spectrometer based on its patented, chip-based technologies (ionchip(R), spraychip(R) and vac-chip(TM)), that is smaller, lighter, quieter, more energy efficient and cheaper to run than conventional mass spectrometer systems.

Mass spectrometry is used across many industry sectors, including government, energy, utilities, pharmaceutical, diagnostics and healthcare, environmental, food and drink, security and defence, and industrial chemicals - a combined market of $3 billion in 2012.

Microsaic Systems was established in 2001 by a team including founders from Imperial College London, and was admitted to AIM in April 2011 under the symbol MSYS.
