Description of the business
Microsaic Systems plc is a high technology company developing and marketing next generation mass spectrometry instruments. MS is widely accepted as one of the most reliable methods for identifying substances, and MS systems are used to accurately identify the chemicals that make up gaseous, liquid and solid samples.

Although fast and sensitive, typical MS products are large, heavy, energy intensive and expensive to acquire and operate. The company has successfully integrated the key MS components onto patented chip technologies called ionchip®, spraychip® and vac-chip™. Due to physical scaling laws associated with the miniaturisation of MS components, the vacuum and power requirements for systems based on Microsaic’s technology are not as great as for larger, conventionally-manufactured MS systems. Consequently, Microsaic’s MS products are substantially smaller, lighter, consume less energy and have lower running costs.

Microsaic Systems plc was established in 2001 as a spin-out from Imperial College London and based at headquarters in Woking since September 2004. The company has successfully developed chip-scale MS technologies. In April 2011 the company was listed on the AIM, and raised £4M before expenses. Microsaic has a large portfolio of 88 patents, of which 36 are granted.

Microsaic partners with customers to deliver products incorporating its MS and other MEMS based technologies.
