About Microsaic Systems

Microsaic Systems plc is a high technology company developing and marketing next generation mass spectrometry (MS) instruments for the analysis of gaseous, liquid and solid samples. Microsaic has successfully miniaturised mass spectrometry into a desktop instrument by integrating the key MS components onto patented chip technologies (called ionchip®, spraychip® and vac-chip™). Microsaic's MS products retain the functionality of larger, conventional MS systems but are substantially smaller, lighter, consume less energy and have lower running costs. The Microsaic 4000 MiD® is the world's smallest MS system.

Mass spectrometry is a 'gold-standard' analytical technique used across many industry sectors, including pharmaceutical, diagnostics and healthcare, government, energy, utilities, environmental, food and drink, security and defence, and industrial chemicals - a combined market of $3.9 billion in 2013. Microsaic aims to introduce compact, deployable MS products, based on its core technology, into a series of these target markets.

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.
