Microsaic Systems PLC has appointed Andrew Darby as Finance Director, with effect from April 16.

The developer of miniaturised chip-based scientific instruments said Darby is replacing Malcolm Bateman who is stepping down from the company and board after eight years.

Bateman will continue as a consultant for a short period in order to support a smooth transition, said the firm.

Darby joins Microsaic on Wednesday April 16 from Active Risk Group PLC, a former AIM-listed company at which he served as Chief Operations Officer and CFO.
